Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix XPR corresponds to the Ammo Pack packaging configuration as defined by Littelfuse. Confirm RoHS compliance status and any applicable agency approvals such as UL or CSA directly on the official datasheet before finalizing procurement specifications. Ensure the selected variant matches the required voltage and current ratings for the target application circuit.

Ptc Resettable Fuses Selection Notes

Select this component when a 60 VDC maximum voltage rating and 300 mA holding current are required for radial mounting. Consider the 2.1 Ohm typical resistance for voltage drop calculations in low-power signal lines. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range while accounting for ambient temperature derating curves provided in the technical documentation.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse POLYFUSE 60R series of resettable fuses. The series provides overcurrent protection solutions characterized by fast response times and high cycle life. The 60R designation indicates a 60 VDC voltage rating family, distinguishing it from higher voltage variants like the 72R series. These devices serve as reusable alternatives to traditional one-time fuses in modern electronic designs.

Ptc Resettable Fuses Replacement Considerations

Direct cross-replacement requires matching the 60V rating, 300mA holding current, and radial lead pitch. Verify physical footprint compatibility including the 7.4mm diameter and 5.1mm lead spacing. Check if alternative manufacturers offer equivalent PTC devices with identical electrical characteristics and approval certifications.
