Re: 4700uF 6.3v and 3300uF 16v in a 10mm Diameter

I disagree with this characterization. I think SMG uses better materials than KMG. I believe they do better in the long term (at standard temperatures that is).

The reason for my logic is that...

Re: 4700uF 6.3v and 3300uF 16v in a 10mm Diameter

I think SMG is overall superior to KMG for general purpose applications. True, SMG is 85c and KMG is 105c, but IIRC, SMG is 2000h @ 85c while KMG is 1000h @ 105c. I use SMG in wall warts where I...

Re: 4700uF 6.3v and 3300uF 16v in a 10mm Diameter

Our forum member Behemot (https://badcaps.net/forum/member.php?u=15285) sells custom made UCC KZN 16V 3300uF capacitors which are 10mm and quite tall and I highy recommend them.

He sells them...

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

It's been some time, finally making some progress with old projects here...

I found the diode, it tests fine. It comes after a resistor marked 01B (1Kohm) which tests fine. There is a 0.2V...

Re: Panasonic FC series - leaking? quality gone?

Huh, PM? PW is supposed to be a miniaturized analog of PM.... That's not very reassuring. Don't they both use the same non-aqueous electrolyte?

It would be nice to use only LXZ, but NCC caps...

Re: Very old Sanyo OS-CONs. Safe to use?

I would certainly not use old OS-CON caps. They do in fact deteriorate. Just open it up and see for yourself. The polymer dielectric should be a moist, glossy black but you will often find in old...

Re: Panasonic FC series - leaking? quality gone?

A bit late to the conversation, but the obvious question would be about Nichicon's FC equivalent which is PW.

Re: Capacitive dropper supplies not lasting

Very informative and constructive post Per! Just to make a small correction the cap you reference is Kemet, not EPCOS.

Re: Question about bipolar electrolytics

Mr. Carlson on Youtube also has a video on how film caps really are actually polar caps.

Newer PSUs will (or should?) come with a four wire SATA power connector instead of the usual 5.

Re: BUDGET 4K graphics cards

I think the highest 3xxx AGP series card is faster than the 4670.

HDMI, no, but DisplayPort yes.

Re: CH341a SPI / IC programmer

The shorter connectors with the fine pitch are also common in LCDs, and are often used as interconnects. I reckon a USB3 header cable would also be suitable.

You can also either take the leads...

Re: [HOWTO] Fix/Repair "Chassis Intruded Fatal Error System Halted" on Asus P5QL

I have a P5K-E that basically ignores the CMOS battery... If power is disconnected from the system completely, it loses all the BIOS settings. Is this also because of a weak transistor?

Thanks

You're saying that the chip reads differently before and then after you soldered and desoldered it?

Re: bios chip problem after 100% programmed using CH341A!

DIFFICULT WAY
You have to apt-get install dependencies first. Don't ask me what they are, I just did them on-the-fly, I don't remember.

Then you have to tell git to fetch from the latest...

Weelcup -

Try flashrom in Linux. It usually succeeds where the Windows CH341A software fails. Make sure you pull the latest snapshot with git.
