Series PPMF

AudioCap Metalized Polypropylene Capacitor PPMF
The PPMF AudioCaps are metalized polypropylene, useful as upgrade from
Mylar or inferior film caps, and available in values large enough to be
ideal for speaker crossover networks. They are built of the best
materials and exhibit excellent electrical and environmental
characteristics. Their superior build quality and high capacitance
values provide a highquality stable, longterm performance not usually
found
in this price range. The goldplated OFHC leads provide longterm high
reliability and excellent solderability, superior to silver
wire because of gold's nonoxidizing properties.
