Schurter PFT Resettable Fuses

Schurter PFT Resettable Fuses are resettable polymer PTC (PPTC) thermistors for high-reliability overcurrent protection. The radial-leaded PFTA, PFTB, and PFTC feature cured, flame-retardant epoxy polymer material that meets UL 94V-0 requirements. The Schurter PFTL is a high-voltage surface-mount fuse that saves PCB space and boosts cost-effectiveness. These resettable fuses are ideal for use in energy storage systems, power supplies, household appliances, and more.
