Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version to confirm compliance with automotive standards if required. Ensure the radial lead spacing matches the target PCB footprint. Confirm that the 16V rating aligns with the operating voltage of the protected circuit. Check for any specific packaging or handling requirements during procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, high-current resettable fuse is needed. The 0.9A hold current suits circuits requiring precise overcurrent limits. Consider the 100A maximum fault current capability for robust short-circuit protection. Evaluate the physical size constraints against the available board space before finalizing the selection.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns MF-RG series of multifuse products. The series is designed for general-purpose circuit protection using PPTC materials. These components are widely used in industries requiring reliable, non-fusible overcurrent protection solutions.

Ptc Resettable Fuses Replacement Considerations

Consult official Bourns documentation for direct substitutes. Verify electrical ratings and physical dimensions match exactly. Cross-reference with other manufacturers only if specifications are identical.
