Ptc Resettable Fuses Procurement Notes

Verify the specific suffix TR1 against official Eaton documentation to confirm reel packaging specifications. Ensure the hold current and voltage ratings align precisely with the target circuit design requirements before procurement. Cross-reference the datasheet for any updates on RoHS compliance status.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC limit and 1.35 A continuous current capacity are required. The 80 mOhms resistance impacts power dissipation; calculate thermal performance accordingly. Ensure the trip current of 2.7 A provides adequate margin above normal operating currents without nuisance tripping.

Ptc Resettable Fuses Part Context

This part belongs to the PolyTron family of resettable fuses from Eaton Electronics Division. These devices serve as reusable alternatives to traditional one-time fusible links, offering cost-effective protection in space-constrained applications requiring reliable overcurrent interruption capabilities.

Ptc Resettable Fuses Replacement Considerations

Consult official Eaton substitution guides for compatible equivalents. Verify that any substitute matches the 30 V rating, 1.35 A hold current, and radial kinked lead form factor to ensure mechanical and electrical compatibility.
