Ptc Resettable Fuses Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical ratings and packaging configuration. Ensure the component meets required agency approvals such as UL or CSA for the target application region. Confirm that the radial lead pitch matches the PCB layout requirements before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile radial solution is required for circuits operating up to 60 VDC. The 100 mA hold current makes it suitable for protecting sensitive low-power data lines and peripheral interfaces. Consider the thermal environment, as the trip time varies with ambient temperature and heat sinking conditions on the PCB.

Ptc Resettable Fuses Part Context

This part belongs to the RXEF series of PolySwitch resettable fuses, which are characterized by low hold currents and high voltage ratings. The series provides a comprehensive set of form factors and termination methods compatible with high-volume electronics assembly processes.
