PolySwitch® Resettable PTCs Surface Mount > LoRho Series Low Rho SMD Series Agency Approvals AGENCY AGENCY FILE NUMBER 078165 * E74889 * R 72161796 * * - See Electrical Characteristic Table for approved part numbers. Description PolySwitch® low resistivity SMD (surface-mount device) is a versatile device well suited for general applications which have space-constrained, low power dissipation and high environmental reliability requirements. The devices can help provide both overcurrent and overtemperature protection for battery pack PCMs (protection circuit modules), circuit PCBA and signal/power I/O interface. The resettable feature ensures the device will “Trip” and protect the application during the faults and yet regain the functions once the error is removed.
