Re: Aishi capacitors
I've just replaced an [B]Aishi CD288Z 105°C[/B] (470uF/10v) because it drawed down a 1.5v supply.
[COLOR="Navy"]
It's in a DSL router (Sagem 1201), and this cap was inserted in the filtering part of 1.5v supply voltage for the main processor.
A chain reaction on the 3.3v and 5v had the Power Supply Supervisor chip to reset main processor. So DSL router lost frequently ADSL carrier.[/COLOR]
diagnostic was the following:
- AISHI cap was bulged
- capacity of 297 uF instead of 470
- measured leakage...

Do you think there were bad caps in there ?Re: New Members - please post your introductions here
