Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix 'K' against official Littelfuse documentation to confirm packaging configuration, as suffixes often denote bulk or tape-and-reel variations. Ensure the selected variant matches the required lead spacing and physical footprint for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm RoHS compliance status and agency approvals relevant to the end application.

Ptc Resettable Fuses Selection Notes

Select this component when a 6 A hold current and 30 VDC maximum voltage are required for circuit protection. The radial lead form factor is suitable for through-hole mounting applications where space allows for a 10.9 mm lead pitch. Consider the 40 mOhms resistance for low-power loss requirements and verify that the 100 A interrupting rating exceeds the prospective fault current of the protected circuit.

Ptc Resettable Fuses Part Context

The RGEF600K belongs to the RGEF series of radial leaded PTC devices from Littelfuse. This series represents a comprehensive line of PolySwitch resettable fuses designed for robust overcurrent protection. The RGEF series is characterized by its compatibility with high-volume assembly methods and compliance with environmental standards such as RoHS, lead-free, and halogen-free specifications.
