Just to be fully advised, the Panasonic ECQ-E capacitors being mentioned on
this list utilize metallized polyester (Mylar), not polypropylene, as a
dielectric. The polyester dielectric has a much higher loss factor at RF
frequencies than the polypropylene.

To avoid disappointment, anyone contemplating the use of surplus Panasonic
capacitors should visit their website to confirm the construction of the
caps before purchase:
