Johanson Dielectrics Type SC ceramic chip capacitors are
designed for AC voltage surge and lightning protection in line-
to-ground interface applications in computer networks, modem,
facsimile and other equipment.
Johanson’s safety capacitor offering includes four different case
sizes and NPO and X7R dielectric materials.
These devices are surface mount ready with barrier terminations
and tape and reel packaging.
Information on capacitor safety ratings and certification details
