Aishi capacitors

[Coconuts 500]

Hello!

I often buy Aishi caps, and use it in various projects (nothing computer-related) and they've worked well for me, over the years. When googling around, I can hardly find any info about people using them. How come? Are these caps really that rarely used?

Any experience with Aishi caps?

Sounds like a cheapo crap brand... But that's just me.

I wouldn't worry too much if it's in basic, low-load projects.

You never did say where you lived - do you buy in electronic shops or on line.
There is only a handful of mentions in all the posts on this site. I guess there are only
a few or one or two of these on a board. If replacing the others, the few cents/pence more to replace these unknowns makes more sense than having to reorder if they are no good.

I have seen quite alot of Aishi capacitors before, and have never seen one failed.
Although saying that, they could have failed without any visible signs.

Or they were in a low-stress environment...

All I gotta say is stick a capxcom in a cfl and see how long it lasts compared to an aishi...

My Antec Earthwatts 430D (first version) has Aishi caps on the primary, with APFC, and it's been running for years, with an overclocked P4 and 880GT, so it pumps out a decent amount of power

Re: Aishi capacitors

They´re also used in CFL´s, like the GE 9W one I just disassembled. 450V 2,7 uF, not bulged but the lamp doesn´t work. Not going to fix it though, was just curious how it looked inside

Re: Aishi capacitors

Aishi seem okay... they claim a rather optimistic 12,000 hours for their caps used in CFLs... pulled one with an ESR of about 4.5 ohms, so not so sure about that claim!

Re: Aishi capacitors

Hehe yeah, I got loads of these 10uF 200v ones from cfls, I dont have an esr meter but I bet a few are bad. Only one is bulged, but thats because the cfl was used on a dimmer

depending on the circuit, it might supposed to have an impedance that high

The CFL was buzzing and flickering, I think it was causing at least half of the problems.

I can imagine, and we got this cheapy cfl that my dad bought, I bet it wont last a year, it buzzes when turned on and is very very very dim at startup, I bet its got say a 1uF cap or likely inside xD

I've seen them a lot in cheapo LED lamps (the ones with 20+ regular 3mm or 5mm LEDs).
They seem to just dry out instead of bulge.

My general rule is that if you haven't heard of a brand, then assume it's bad.

Re: Aishi capacitors

Just figured out that my sneezing sounds like "Aishiii" (I´m having a boring cold at the moment), so you can actually "hear" the brand .... Kind of ... But that doesn´t make it any good though

Re: Aishi capacitors

Now that must be where Aishi get their electrolyte from - the employees with colds sneeze into the cans

Re: Aishi capacitors

that type of led bulb is junk regardless of mfr/brand.even cheap caps will outlast china 5mm led's.
