SAFETY CERTIFIED CAPACITORS
Johanson Dielectrics Type SC ceramic chip capacitors are
designed for AC voltage surge and lightning protection in
line-to-ground interface applications in computer network,
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.
Additional information on capacitor safety ratings may be
