Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation when ordering, as variations such as AP or -2 may indicate differences in packaging or certification status. Confirm RoHS compliance requirements against the latest manufacturer documentation. Ensure the selected variant matches the required interrupting rating and voltage specifications for the target application circuit.

Ptc Resettable Fuses Selection Notes

Select this component based on the 650 mA hold current requirement and 72 VDC system voltage. Verify that the 40 A interrupting rating exceeds the prospective fault current available at the installation point. Consider the thermal environment to ensure the operating temperature range accommodates the ambient conditions without premature tripping.
