PPTC resettable fuses

26 May 2010 Circuit & System Protection

Bourns has integrated two polymer positive temperature coefficient (PPTC) resettable fuses into a single package. This new Multifuse device contains twin 250 V polymer PTC resettable fuses and decreases the circuit protection footprint by 50% on the circuit board. Designated the model MF-SD013/250-2, the device provides both tip and ring over-current protection and aids compliance with ITU-T K.20, K21 and K.45 industry standards as well as Telcordia GR-1089 intra building. Multifuse devices are well suited for telecommunication applications including customer premise equipment and line cards.
