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

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

Chicago, October 14, 2019 — Littelfuse, Inc. (NASDAQ: LFUS) a global manufacturer of leading technologies in circuit protection, power control and sensing, today announced a new series of 250V 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.

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

“Featuring two resistance-matched PPTCs in a single surface-mount housing, the TSM250-130 Series delivers Tip and Ring overcurrent protection while using 50% less PCB area,” said Stephen Li, Global Product Manager at Littelfuse. “With its high surge capability, it helps end users comply with ITU-T K.20, K.21 and K.45 as well as Telcordia GR-1089 intra-building standards.”

The TSM250-130 Series PPTCs offer these key benefits:

  • Two 250V PPTCs in single housing reduces PCB area by 50%.
  • Resistance matched PPTCs offer Tip and Ring resistance balance.
