Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '-AP' aligns with the required packaging configuration, such as cut tape or reel, as indicated in official Littelfuse documentation. Confirm RoHS compliance status and agency approvals relevant to the target market before finalizing procurement orders to ensure regulatory adherence.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.85 A hold current and 30 VDC rating are required for radial-leaded applications. Ensure the 100 A interrupting rating meets the system's fault current requirements. Verify that the physical dimensions and lead spacing fit the available PCB footprint constraints.

Ptc Resettable Fuses Part Context

The RUEF series belongs to Littelfuse's PolySwitch family of resettable fuses. These devices utilize polymer positive temperature coefficient technology to provide automatic circuit protection. The RUEF185-AP variant specifically addresses low-voltage, moderate-current protection needs in consumer electronics and industrial control systems requiring radial termination.
