Series PPF ALPHA
AudioCap Polypropylene & Aluminum Film & Foil PPF Alpha

The PPF Alpha AudioCap is an excellent film & foil capacitor for all audio circuits and power supplies, a fine upgrade from metalized film. It provides low distortion and long-term reliability and exhibits excellent electrical and environmental characteristics. Its sonics are clear and clean, the choice wherever accuracy is important. Its superior build quality provides the designer with high-quality, stability, and long-life in a film & foil cap seldom available in this price range. The gold-plated OFHC leads provide long-term high reliability and excellent solderablility, superior to silver wire owing to gold�s non-oxidizing properties.
