Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'UFF' against official Littelfuse documentation to confirm exact packaging or tape-and-reel specifications, as standard listings may default to bulk or other variants. Confirm RoHS compliance status and ensure the component matches the required hold and trip currents for the target circuit design before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded, resettable fuse is required for 30 VDC circuits needing approximately 1.35 A hold current. Ensure the application environment stays within the -40°C to +85°C operating range. Consider the 40 A max fault current rating and low initial resistance for compatibility with sensitive downstream components and PCB layout constraints.

Ptc Resettable Fuses Part Context

The RLD30P135UFF is part of the PolySwitch RLD30 series, which represents a comprehensive set of radial leaded PPTC products from Littelfuse. This series balances a 30 V voltage rating with various hold current options, providing robust overcurrent protection for semiconductors and electronic components in space-constrained applications.

Ptc Resettable Fuses Replacement Considerations

Consult Littelfuse official substitution guides for direct equivalents within the RLD30 series. Verify that any substitute maintains the 30 VDC rating, 1.35 A hold current, and radial leaded form factor to ensure mechanical and electrical compatibility.
