Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

------------------------------------

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures. You may do so in a thread if the off-site link you're posting is relevant to the topic, but otherwise, don't do it. If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

      I think this would be in relation to storage in that case (I.e. when the caps have never been used)

        Right, just like they last longer in a circuit.

          Alluminum caps rarely short out in service. Usually they just dry out or bloat.
          Never had one explode or bulge even if it was old, but that is 5years top.

          However, tantalums are a completely different story. Those suckers will burn a hole in your board for no reason at all.

              Because at the time they still thought thought KZG was good. Once KZG had been out a few years we figured out that they had issues.

                Re: The Good Capacitors Photo Thread

                Quick question here! I got some presumably Panasonic FR capacitors off some dead motherboard, but i am not sure if they are real. They have the usual T shaped vent and they look like Panasonics, but there is no [M] logo on them. They are rated for 16V 100uF and the printing quality is somewhat questionable (big print). 16V 1000uF 105c FR 23IDA.
                I can put text here?!

                  Re: The Good Capacitors Photo Thread

                  Panasonic FR series doesn't have the M logo on them, and it's plain white ink on black plastic.

                  I actually have some 100uF 16v panasonic FR capacitors, here's how they look:



                  btw, the 100uF shouldn't have a T vent at all, the size is too small for the capacitors to do any real damage or have enough gas to explode, so usually such small capacitors don't have any vent.

                    I know small caps don't have vents I meant 1000uF not 100uF They are probably real ones. Thanks for a quick reply mariushm!

                        Here are some caps i have, that i do not think they have pictures of them posted here.

                        Panasonic FZ: Dark blue, light golden stripe.


                        Panasonic HFQ: Got them from a Compaq branded psu (probbably Delta). Dark blue, white stripe.


                        Philips M series? Not sure. Got them from an old monitor. They seem fine, i use them for psus. Blue, black stripe.


                        Panasonic FJ: Black, golden stripe. Very good caps.


                        Panasonic FR: Black, white stripe. NB! They do not have the [M] logo, but they are genuine! (thank you Mariushm for the info!)


                        Rubycon W: Very old caps, from an old monitor. I use them for psus, probably not low enough ESR for boards. Light blue, dark blue stripe.


                        Fujitsu M: Yellow, black stripe. Not sure of the quality, should be ok. Vent is like the Sanyo K vent, but different from Rubycon K vent.


                        Panasonic FL: They look like polys (4v, 680uf, tiny, flat top, no vent) Black, golden stripe.


                        Sanyo CZ: Light green, white stripe.


                        Nichicon RZ: Not sure if genuine, they have a generic round (circles) bung. Black, white stripe.

                          Can anyone give light onto good Ceramic caps? What brands should I go for and what rating for motherboards/gpus?

                            As for SMD ceramics, the best is X7R electrolyte, I think it does not really depend from which manufacturer but maybe somebody will correct me.

                            As for radial ceramics, not really sure, I usually buy whatever they sell me in shop if I need something and don't have it "on stock" digged from already dead and dismounted HW.

                              There are loads of types of ceramic capacitors... and there's several temperature ratings for such resistors, X5R, X7R and C0G/NPO being some of the best. NPO is actually above x5r and x7r as it's not as sensitive to vibrations (piezoelectric effect).

                              But these ratings are loosely defined... a x5r build with some specific components by a manufacturer could have the same performance as a capacitor rated as X7R by another company.. you can't be 100% sure.
                              Or, for example, a 2.2uF X5R in 0805 package may have the same performance as a 2.2uF X7R in 0402 or 0603 package (or footprint, whatever).

                              It's just safe to not go lower than X5R.

                              Read this article for some info about how ceramic capacitors are affected by voltage and temperature : http://www.maximintegrated.com/app-n...ex.mvp/id/5527
