Sold in complete kits or individually, Electrocube’s pfc Precision Film Capacitors and Standards are stabilized silvered mica and polystyrene dielectric capacitors. They feature a wide application for calibration standards, breadboard components, circuit simulation devices and precision components in stable frequency or timing networks. The kit is a close-to tolerance, stable capacitor set with calibration traceable to the National Bureau of Standards.
Obtain a capacitance value of four significant figures with an accuracy of ±0.1% by quick and easy insertion of pfc Standard Capacitors into adapter fixture.
