What is this capacitor

Please could you help identify this type of capacitor. I Just it out of a Rotel RCD-965BX position C202. Numbers on it are 120P, F630, CN KS.
Thanks
Tom

DEAD - VERY DEAD.

L.O.L.

It looks like a 120pF/630V Polypropylene but can you give us an idea of its size.

More to the point - HOW has a 630V cap got into that state ?

Polyprops are usually pretty reliable unless they are overheated.

10mm long about 3.5mm diameter

KatieandDad 6th April 2012 11:15 AM

That sounds about right. The larger diameter is because of its high voltage rating.

Might be worth waiting to see if anyone has the schematics to confirm the value.

There isn't a C202

Purely from its voltage rating I would guess that its C001 - across the mains switch. I am guessing though.

It is a Philips polystyrene capacitor of 120pF/1% 630V.

it's in the bottom right hand corner of U112 between 0AR0 and 0AR1-

Beat me to it.

Philips 120pF F=+/-1% 630V CN= Date KS= polystyrene (Unlacquered version)

I agree with ELVEE - my mistake polystyrene not polypropylene.

If you can ascertain where it is in the circuit we can offer a suggestion for a replacement.

I guess this would do as a replacement
