Telecom PTC Devices
Data Sheets »

Telecommunications and Networking PTC Devices are available in surface mount and radial leaded configurations. These devices are designed to protect telecom equipment against short duration high voltage fault currents generated from lightning and power cross conditions. Holding currents range from 0.055 amps to 0.400 amps. Maximum operating voltages range from 60 to 250 VDC and maximum interrupting voltages range from 250 to 600 VAC. The telecom PTC Devices help telecom equipment meet the protection requirements specified in Telcordia GR-1089 and UL 60950/EN60950/IEC60950 standards plus the ITU K.20, K.21 and K.44 requirements. All series are lead free and RoHS Compliant.
