Jantzen 0.15uF 1200V Z-Silver Capacitor Jantzen Silver capacitors are possibly the most detailed caps on the market. These caps are constructed of a specially wound metallized polypropylene to minimize inner vibration, which keeps microphonic effects as low as possible. Silver Series caps also feature high purity silver leads for the absolute best signal transfer, resin-sealed end caps to protect against humidity, and flame-retardant tape wrap. The result is a reliable and consistent product that facilitates the construction of high quality, precision crossovers. Silver Series caps are natural sounding without audible coloration of the audio signal, delivering an authentic soundstage and neutral tonal balance. Sonically, they behave more like a fine piece of wire than a capacitor. Truly, an outstanding audio component! Rated at 1200 VDC, 2% tolerance.
