Surge Protection and Safety Capacitors

The industry’s widest range of surge and safety multilayer ceramic chip capacitors, with full certification to UL (UL and CSA) and TÜV (IEC and EN), protect equipment specified to IEC60950. Syfer’s Surge Protection (SP) series of Y2/X1 and Y3/Y2 devices offer case sizes from 1808 to 2220, with an extended capacitance range of up to 1nF in a standard 1808 case.

The PY2 family of Y2/X1 and X2 safety capacitors has case sizes of 2211, 2215 and 2220, with capacitance values up to 4.7nF for Y2 versions in the 2220 case. All versions are available with FlexiCap™ terminations which reduce susceptibility to cracking due to mechanical stress during assembly.
