Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm datasheet revisions match design requirements. Ensure storage conditions respect moisture sensitivity levels. Validate RoHS compliance status for specific manufacturing batches prior to integration into final assemblies.

Ptc Resettable Fuses Selection Notes

Select this component when a 2.5 A hold current and 15 VDC rating suit the circuit design. Consider the 2920 footprint for board space constraints. Evaluate thermal management needs given the 1.5 W power dissipation limit. Compare against standard fuses where resettable functionality is required for maintenance reduction.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse PolySwitch SMD series of polymer positive temperature coefficient devices. These solid-state fuses increase resistance upon heating to limit fault currents. The series provides an alternative to traditional fusible links by enabling repeated use after fault clearance in various electronic applications.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other 2.5 A, 15 VDC PolySwitch devices in the 2920 package from Littelfuse. Verify identical electrical parameters and physical dimensions before substitution. Cross-reference with equivalent offerings from other manufacturers ensuring matching hold and trip characteristics.
