What is a telecom PTC device? Telecom PTC devices are designed to protect telecom equipment against short duration high voltage fault currents generated from lightning and power cross conditions. Telecommunication PTC Devices are available in surface mount and radial leaded configurations. PTC telecom device 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 telecommunication 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 telecom PTC device series are lead free and RoHS Compliant.
