Polycarbonate capacitors are capacitors that have a polycarbonate dielectric.
Polycarbonate capacitors range in values from 100pF to 10µF, and have working voltages up to 400V DC.
Their tolerance levels are 5% and 10%.
Their temperature coefficients are about 100ppm/°C, and are fairly constant over the operating range
of 55°C to 100°C. This makes them preferred to polyester capacitors for filtering and timing circuits.
