Polystyrene Film Capacitor 20pF 50V

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. Specifications Parameter Value Dielectric Polystyrene (PS) Capacitance 20pF Tolerance ±5% Rated Voltage 50V Dissipation Factor typ. ≤0.1% at 1kHz Mounting Radial through-hole Body Size 5.5mm x 10.5mm Operating Temp. Range −40°C to +85°C Construction Polystyrene film + foil, epoxy/polyester wrap. Applications Precision oscillator and timing circuits (LC tank capacitors). RF circuits and filter networks where high Q and low loss are required. Sample-and-hold, ADC front-end, and low-drift analog conditioning. Vintage audio and synthesizer modules requiring original-style polystyrene caps.
