Ptc Resettable Fuses Procurement Notes

Verify that the ordering suffix matches the required voltage and current ratings, as variations exist within the MF-LSMF series. Confirm compliance with RoHS directives and country of origin requirements during procurement. Ensure the selected variant aligns with specific thermal and electrical constraints of the target application to prevent performance discrepancies.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile surface-mount solution is required for 16V DC circuits. The 3.3A hold current and 55mΩ resistance make it suitable for applications demanding minimal power loss. Consider the 2920 footprint compatibility with existing PCB designs. Evaluate thermal derating requirements based on ambient operating conditions to ensure reliable tripping characteristics.

Ptc Resettable Fuses Part Context

This part is a member of the Bourns MF-LSMF series of PTC resettable fuses. The series offers various current and voltage ratings packaged in standard SMD footprints. These components are engineered to replace traditional fusible links in modern electronics, providing reusable protection against overcurrent events while maintaining a small physical profile for dense board layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 16V voltage rating, 3.3A hold current, and 2920 package dimensions. Verify that alternative PPTC devices offer comparable trip times and resistance values to maintain circuit integrity. Cross-reference approval agency certifications if regulatory compliance is mandatory for the end product.
