I'd have no hesitation in us= ing the poly caps.

Some ceramics are terrible.

The proo= f of the pudding comes in whether or not they heat up, but at 10W...

Hi all.

I'm trying to select some 8n2 capacitors for= use in a low pass filter at 630m
They need to handle about = 10 Watts maximum but I can't d= ecide if I should
avoid or accept Polyester (PET),  Multi la= yer ceramic or Polypropylene.

The polyester isn= 9;t one I've worked with before with= RF, but it seems available in 5%
and with voltages around= 250V DC at reasonable cost.

Any thoughts??
