Ptc Resettable Fuses Procurement Notes

Verify the manufacturer part number FRU700-30F against official Fuzetec or RFE documentation to ensure authenticity. Confirm that the required electrical parameters, specifically the 30V rating and 7A hold current, match the design specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Ptc Resettable Fuses Selection Notes

Select this component when a 30V maximum voltage and 7A continuous hold current are required for overcurrent protection. The radial disc package suits applications requiring through-hole integration. Consider the 14A trip current threshold for fault detection sensitivity. Evaluate the thermal environment to ensure operation remains within the -40°C to 85°C range during normal and fault conditions.

Ptc Resettable Fuses Part Context

This part belongs to the FRU series of radial leaded PTC resettable fuses from Fuzetec Technology. The series includes variants such as FRU800-30F and FRU900-30F, differentiated primarily by their current ratings. These components utilize polymeric positive temperature coefficient technology to provide reusable overcurrent protection in electronic circuits.

Ptc Resettable Fuses Replacement Considerations

Public cross-reference data lists RUEF700, MF-R700, 30R700, and RLD30P700UF as compatible substitutes. Verify that any replacement maintains the same 30V voltage rating and equivalent 7A hold current. Ensure the physical dimensions and lead spacing of the substitute part fit the existing PCB footprint without modification.
