Littelfuse Dual channel PPTC with 50% Smaller Footprint Protects Telecom Equipment from Overcurrents

Littelfuse TSM250-130

Conserves PCB space by featuring two Telecom PPTCs in a smaller surface-mount footprint

Littelfuse announced a new series of 250 V Telecom PPTCs designed to help make telecom and network equipment more reliable. The TSM250-130 series protects against power cross and induced power surges as defined in ITU, Telcordia GR1089 and IEC 62368-1. Because it combines two resistance-matched PPTCs in a single surface-mount housing, it reduces the board space required by 50%, simplifies assembly, and offers Tip and Ring resistance balance.

Littelfuse - TSM250-130

Part of the Littelfuse PolySwitch® family of resettable overcurrent protection devices for telecommunications and networking equipment, the new series is ideal for:

  • Customer Premise Equipment (CPE)
  • Central Office (CO) equipment
  • Subscriber Line Interface Cards (SLIC)
  • VoIP port on set top boxes

The TSM250-130 Series PPTCs offer these key benefits:

  • Two 250 V PPTCs in single housing reduces PCB area by 50%.
  • Resistance matched PPTCs offer Tip and Ring resistance balance.
  • Very high voltage surge capability aids compliance with industry certification.
