HIGH VOLTAGE CAPACITORS

Unencapsulated Mica Paper Capacitors

You can make your own capacitor assembly to uniquely fit available space using unencapsulated capacitor windings potted in place. Wound with high grade mica paper, pressed flat and impregnated with a polymer, unencapsulated capacitors allow you to supply the final package. Use them where weight and size are of concern as in applications like satellites, transmitting power supplies for EMCs and in Foil Initiators.
