Raychem Polyswitch Circuit Protection TSM600-250

TE Connectivity

TE Connectivity announces the introduction of a new Raychem Circuit Protection Polyswitch TSM600-250 over-current protection device for DSL and other telecommunications network equipment applications. The small-footprint, low-resistance, surface-mount device provides tandem resettable over-current circuit protection for use in high-density multi-port line cards and other telecommunications network equipment. The TSM600-250 device incorporates two matched, low-resistance PPTC (polymeric positive temperature coefficient) components into a single device yielding balanced protection on tip-and-ring lines with minimal attenuation of data transmission.
