    Look up "DAC-19M015" in Google and go to the ShopJimmy.com result.

    If you don't see it in the small pic, use the enlarge function...

    Comes with pre-blown cap!!




    Send me a dozen, will ya?!?
    I emailed and asked if all his parts come with pre-bloated caps like that one.

        Not unless your real name is Pythagoras and you're really, really old.


        But then I never called it your equation, I called it the equation which you used, meaning the equation which you used in your explanation of the circumstance under which ESR is effectively equal to impedence.

            I didn't realize Pythagoras knew anything about ESR and reactance.

                    Yes. They sold the pre-blown ones to ShopJimmy.

                    Of course, at the lower price you can always buy the caps and still be less than SJ.


                    Two on ebay for $54.

                        Well, somebody angered one of the caps gods, and he visited a bad electrolyte plague upon us all.

                            Is it no harm to replace with capacitor without ripple current rating?
                            by chth96
                            When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


                            Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
                            But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
                            Rubycon YK DataSheet (b...

                            Capacitor Diarrhea - Nichicon PL Series
                            by DrewPhillips
                            Hello All, I have on the bench a couple of PSU's which have some failed Nichicon PL series caps. They didn't "puke" their guts through the top, but instead "diarrhea'ed" corrosive brown electrolyte through the bottom, down the legs and onto the board. On one cap, the electrolyte rotted the cap right off the board leaving 2 little stubs, and also corroded a trace on the foil side.

                            The PSU's are Power-One MAP series and are ringing-choke topology. The semiconductors have date codes in 1993. The PSU's were used in a commercial application, fan-cooled. They had failed...

                            Repair of Sign WiFi Smart Plug PCB: SA-P302A v1.2 due to bad caps - with schematic
                            by Per Hansson
                            I have repaired a Sign WiFi Smart Plug with model number: SNSM-WASINGLE sold by Spares Nordic AB in Sweden.
                            The fault condition was that the device gave no signs of life: pressing the push button did not cycle the internal relay and the blue LED did not come on and it was not seen on the WiFi network.
                            The fault was very simple, capacitor C3 on the PCB with writing "KSJ" and "LOWESR" had literally blown its top off, after replacing it the device works fine again!

                            As I find linear high voltage regulator designs interesting I drew up the attached schematic...

                            by Prolog
                            Hi people, I hope this is the correct spot to post this, I'm new to the forum.

                            I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

                            I hope these photos make it clear which component I am referring to:
                            (yes, the soldering is a bit botched from removing the blown one, I know)

                            I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

                            Cyberpower 1500AVR UPS repair
                            by quickname
                            I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

                            Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

                            I decided to verify that the batteries were...
