Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm exact electrical characteristics and packaging configuration. Ensure the selected variant matches the required hold current and voltage ratings for the target circuit design. Confirm agency approvals such as UL and CSA are present on the datasheet for the specific part number being procured.

Ptc Resettable Fuses Selection Notes

Select this component when circuits require resettable protection with high holding currents up to 14 A in low-voltage environments. The radial leaded package suits automated assembly processes. Verify that the 16 VDC maximum voltage rating aligns with the system's operating voltage. Consider the 100 A fault current capability for short-circuit scenarios.

Ptc Resettable Fuses Part Context

The RGEF1100 belongs to the RGEF series of radial-leaded PolySwitch devices. This series provides a comprehensive set of PPTC products characterized by low hold currents and wide form factors. The component serves as a solid-state alternative to single-use fuses, offering repeated protection cycles after tripping events.

Ptc Resettable Fuses Replacement Considerations

The RGEF800-1 is a documented substitute within the same RGEF series, sharing identical physical dimensions and voltage ratings but featuring an 8 A hold current instead of 11 A.
