Re: KZG - KZJ - Same Electrolyte
I don't know if the origin (manufacturing plant) of the electrolyte and foil have a bearing on reliability, but it seems that some batches of KZGs don't fail as much as others. KZE and KZN also...

Re: Tethering for smartwatch phones
The capability has existed for maybe 10-15+ years in phones, either through Bluetooth Dial-Up Networking (commonly found in Nokia 2G and later phones) or through Wi-Fi hotspot functionality (aka...

Re: The 2017 Operating System Thread
Nobody using Fedora? I'm at F25 x86_64 on most of my daily-use Core 2 laptops, with F21 or F24 on a few. Of course, I got rid of the stock UI/WM and replaced it with XFCE or LXDE. Lower-spec and...

Re: Carbon film vs metal film resistors
Correct - the greatest contribution to resistor inductance probably comes from the leads and end-caps. If they contain any ferromagnetic material (iron, steel, nickel, cobalt, etc.), their relative...

Re: Observations on cap composition and stability
I suppose it's a bit early to take a call on reliability, but Samyoung seem to have some claimed 5000 hour, 105c, moderate/high ripple-current, high-voltage electrolytics. I have some Samyoung NFK...

Re: Problems with trying Ubuntu 16.04 LTS
May be true of the stock Debian distro, but there are derivative distros which don't require any shell use at all. For a newbie, Knoppix 7.4 (which is basically a read-only live DVD Debian-derived...

Re: motherboard cap question
Panny FL doesn't fail easily unless there is a combination of heat *and* high ripple current, in which case it can bulge and spill some thick black goo. If they look OK, I'd leave all the FLs alone,...

Re: Recapping of Asus P5B
At first glance, they looked like polymers of either Nichicon or some lesser-known off-brand. On second glance, it looks like it could be Panasonic FL (electrolytic) in clear lacquer finish. If so,...

Re: KZG 6.3v 820uf replacement
It has now completed several hours of burn-in running Memtest86 without a single bit-error - previously, it used to throw up a random error or two on every pass. I'd recommend KZV as an 8mm...

Re: KZG 6.3v 820uf replacement
11 years on the shelf, while still retaining spec., is no mean feat. For at least part of that time, it has been stored in sideways position, when the electrolyte no longer seals the lower bung and...

Re: KZG 6.3v 820uf replacement
It's possible that there have been failed KZVs in hot Prescott SFF VRMs, but I haven't actually seen any failed KZVs first-hand so far, but then again, I haven't seen too many KZVs at all. They were...

Re: Ltec LZG
Size may not fit, but film capacitors like Wima MKS02 and MKS2XL will handily exceed the specs and durability of any electrolytic of value 1uF/50V.

Re: KZG 6.3v 820uf replacement
Has anybody found the datasheet of NCC KZV? The only ones I've found are references from KZG and KZJ datasheets that show KZV as being lower impedance than those two. It also seems to be a 2000-hr...

Re: Led lamp - won't work in cold enviroment
You probably don't want to use aqueous electrolytics (ultra-low ESRs) in which the water is likely to freeze. Older non-aqueous electrolytics like NCC LXV/LXY/LXZ or Nichicon PJ/PW or Panasonic FC,...
