Product Description
PolySwitch Radial Leaded PTC Resettable PPTC 250V 0.12A For Telecom Protection
Description Of The PTC Resettable PPTC 250V 0.12A
The TRF series is designed to protect against short duration high voltage fault currents (power cross or power induction surge) typically found in telecom applications (250Vrms). The series can be used to help telecom networking equipment meet the protection requirements specified in ITU K.20 and K.21.
Features Of The PTC Resettable PPTC 250V 0.12A
◆ Fast time-to-trip
◆ Binned and sorted narrow resistance ranges available
◆ 0.08 — 0.18 Hold current range, 60VDC operating voltage
◆ 250VAC interrupt rating
◆ Radial Leaded Devices
◆ Cured, flame retardant epoxy polymer insulating material meets UL 94V-0 requirements
◆ Bulk Package, or tape and reel available on most models
◆ RoHS, Reach, HF compliance
Applications Of The PTC Resettable PPTC 250V 0.12A
Almost anywhere there is a low voltage power supply,up to DC60V and a load to be protected, including:
◆ Security and fire alarm systems
◆ Analog and digital line cards
◆ Modems and DSL
◆ Customer Premises Equipment (CPE)
◆ Central Office (CO)/ telecom centers
◆ LAN/WAN equipment
◆ Access equipment
