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 high-quality stable, long-term performance not usually found in this price range. The gold-plated OFHC leads provide long-term high reliability and excellent solderability, superior to silver wire because of gold's non-oxidizing properties.
