Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix matches the required packaging and tolerance specifications. Confirm that the radial lead pitch aligns with the target PCB footprint. Ensure the application environment stays within the specified operating temperature range to maintain reliable tripping characteristics. Check RoHS compliance status if restricted substances are a concern for the final assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a low holding current near 100 mA is required for sensitive circuit protection. The 60 VDC rating suits low-voltage DC applications. Consider the physical size constraints as the radial package requires specific board space. Evaluate the thermal environment to ensure the device can cool sufficiently between fault events for proper reset functionality.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns Multifuse MF-R series of resettable fuses. These devices utilize polymer positive temperature coefficient technology to provide reusable overcurrent protection. The series offers various hold currents and voltage ratings to suit different circuit requirements while maintaining a compact form factor suitable for dense PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 100 mA hold current, 200 mA trip current, and 60 VDC rating. Verify that alternative PTC devices have compatible radial lead spacing and similar resistance values to ensure circuit performance parity.
