Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '0-99' against official Bourns documentation to confirm packaging and compliance details. Confirm availability status as this part may be subject to obsolescence or limited supply constraints. Ensure the selected variant matches the required axial or radial configuration for your assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when a 0.3 A hold current and 60 V rating are required for circuit protection. Consider the 0.76 Ohm resistance and thermal characteristics for power dissipation analysis. Verify that the 40 A maximum fault current capability aligns with the system's potential short-circuit levels.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns MF-R series of multifuse resettable fuses. These components are engineered for high-reliability circuit protection in demanding environments. The series provides a cost-effective alternative to traditional fuses by eliminating the need for replacement after tripping events.

Ptc Resettable Fuses Replacement Considerations

The MF-R020-AP and MF-R020-2 are listed as possible replacements by distributors, though they feature different electrical ratings (0.2 A hold current). Verify compatibility before substitution.
