TSM250-130 Dual channel PPTC for Overcurrent Protection in Telecom Equipment
Littelfuse, Inc has announced a new series (TSM250-130) of 250V PPTCs for over current protection in telecom and network equipments. The New series of PPTCs protects the devices against power cross and induced power surges as defined in ITU, Telcordia GR 1089 and IEC 62368-1. This increases the reliability of the telecom and network equipments. It combines two resistance-matched PPTCs in a single surface-mounted housing; hence it reduces the board space by 50%, simplifies assembly, and offers Tip and Ring resistance balance. They are compliant with industry certifications such as ITU-T K.20, K.21 and K.45 as well as Telcordia GR-1089 intra-building.
Features of TSM250-130:
- Two 250V PPTCs in a single housing
- Reduces the PCB area by 50%.
- Resistance matched PPTCs offer TIP and Ring resistance balance.
- Very high voltage surge capability and complies with RoHS.
