Hey Guys so, I am replacing some old caps on a Kenwood Amplifier,
There are two caps I am replacing.
0.01 uF Ceramic +100% -0%
0.15 uF Mylar +- 10%
Now all was fine until I bought the replacement caps and noticed both are incredibly smaller than the old ones, here is a photo of the two side by side of the new ones
The top ones are 0.15 uF.
The replacement I bought is rated at 100V 10%
The bottom ones are 0.01uF (103), the big blue one is rated @ 3kV and the small blue one is rated at 100v 10%
Now looking at where they are located on the circuit the 103 caps are for some high frequency filtering of some sort, I have no idea why the caps that were put there are so big since the output on the TF is 50V RMS
On the other hand the 0.15uF caps look like some sort of snubber from the output of the `power transistors there is a 2 Watt resistor before the cap.
Here are the diagrams for both.
The parts sheet for this amp mentions nothing about the rated voltage for these capacitors only the tolerance.
Basically will the small capacitors be fine in this situation ?
Regards
Byron
