HIGH VOLTAGE CAPACITORS

Wrap and Fill Mica Paper

Wrap and Fill Mica Paper

For the final package with the least additional space and cost specify wrap-and-fill type KVx capacitors. Wound with high grade mica paper, pressed flat and impregnated with a polymer, they are wrapped with Mylar or fiberglass tape, and end-potted with epoxy. The tape and epoxy provide excellent resistance to moisture. Wrap-and-fill capacitors are in applications like power supplies for radar transmission, TWTs, pulse forming networks, jet ignition starting systems, and are great for breadboarding.
