The LVM2P-015R10431 from Littlefuse is a Polymer Protected Metal Oxide Varistor that is designed for line voltage applications. This varistor requires a DC voltage of 430 V with a DC resistance of over 10 MΩ @100 V and has a rated power of 0.25 W. It incorporates PolySwitch PPTC (Polymeric Positive Temperature Coefficient) technology and MOV (Metal Oxide Varistor) technology to help reduce board space requirements and component count. This RoHS compliant varistor provide current limiting during overcurrent events and voltage clamping during overvoltage events. It helps address the need for resettable circuit protection devices for use in cost-sensitive PSTN (Public Switched Telephone Network) and VoIP (Voice over Internet Protocol) telephony equipment. This varistor resets itself after a fault condition is removed and power is cycled, thereby continuing the operation of the equipment. It is available in a through-hole package that measures 12.0 x 28.5 x 7.4 mm and is ideal for cordless telephones, security systems, MDF modules, VoIP gateways, fax machines, data modems, analog and ISDN linecards and set-top box applications.
