The LVM2P-035R14431 from Littelfuse is a Polymer-Protected Metal Oxide Varistor that is ideal for VoIP gateways, fax machines, data modems, set-top boxes, security systems, MDF modules, analog and ISDN linecards, and cordless telephone applications. It has an AC voltage rating of 240 V, a DC voltage rating of 430 V, and a clamping voltage of up to 710 V. This varistor limits the in-rush current during over-current events and clamps the voltage during over-voltage events. It resets itself once the fault condition is removed and power is cycled, ensuring that the equipment remains operational.
This varistor helps address the need for resettable circuit protection devices for use in a cost-sensitive public switched telephone networks (PSTN) and voice-over-internet protocol (VoIP) telephony equipment. It also helps equipment comply with global safety standards, including UL 60950, TIA-968-A, IEC 60950, and ITU-T K.20/K.21. This RoHS-compliant varistor integrates PolySwitch polymeric positive temperature coefficient (PPTC) technology and metal oxide varistor (MOV) technology in a single package to reduce board space requirements and component count. It is available in a through-hole package that measures 16.0 x 24.0 x 7.4 mm.
