Ptc Resettable Fuses Procurement Notes

Verify the specific suffix AP-99 against official Bourns documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required hold and trip current ratings for your design. Cross-reference the UL file number and RoHS compliance status with the manufacturer's latest datasheet before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when designing circuits requiring high-current resettable protection with radial leads. Consider the 11A hold current limit and 22A trip threshold to ensure proper coordination with upstream fuses or breakers. Evaluate the operating temperature range and physical dimensions to fit within the target enclosure constraints.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns MFR series of high-current resettable fuses. The series is designed for applications demanding reliable overcurrent protection with rapid response times. The MF-R110 variant specifically targets high-amperage circuits where standard polymeric fuses may be insufficient or require frequent replacement.

Ptc Resettable Fuses Replacement Considerations

Consult Bourns official substitution guides for equivalent MFR series parts with matching electrical ratings. Verify that any alternative maintains the same voltage rating, hold current, and package dimensions to ensure mechanical and electrical compatibility.
