Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to ensure correct packaging and tolerance specifications. Confirm that the required hold and trip currents align with the circuit design parameters before procurement. Check for any recent product change notifications regarding material or dimensional updates.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is required for high-current applications up to 8 A. Ensure the system voltage does not exceed the 16 VDC rating. Consider the thermal environment, as the operating range extends to 85°C. Verify that the 100 A maximum fault current capability meets the prospective short-circuit requirements of the target circuit.
