Ceramic capacitor 331K. Value??

[Jan Dupont]

One of my TV’s, a Philips 28PW6322/11, crashed with a loud “Bang” the other day.

I found that the main fuse (4A) was blown, one of the rectifier diodes was shorted, and one small blue ceramic cap marked 331K 1 KW was “exploded”.

As I am normally not into TV’s, I am not sure about the precise value of the cap.
As I recall, 331K means 330pF x 1000 = 330nF….

Is this correct?????

By the way!
Has some of you experienced the same problem????

I think K is for tolerance ...

So I think it is probably 330 pF, +/- 10%

But, that begs the question ... what would a 330 pF cap be for in the power supply. A snubber I would guess, but it seems like a small value for that purpose.

Yup, 331 = 33*10^1

Thanks a lot for the help

I guess this capacitor is used against reverse current. If the the diode was shorted, it may explain why this capacitor was blown.
I had the same doubt about the value...I really thought it was 330nf.
