Polystyrene Film Capacitor 20pF 50V
The Polystyrene Film Capacitor 20pF 50V is a precision, low-loss film capacitor using a polystyrene dielectric (Styroflex / PS) and foil electrodes, designed for timing, RF tank circuits, and precision analog applications where low dielectric absorption and long-term stability are required. Supplied in radial through-hole packages and is rated for operation to 50V DC.
Features
- Polystyrene (PS / Styroflex) dielectric with foil electrodes for very low dielectric absorption and high Q.
- Nominal capacitance 20pF with typical tolerance ±5%.
- Rated voltage 50V DC.
- Extremely low dissipation factor and leakage.
- Radial through-hole leaded package for easy hand-wiring or PCB mounting.
