Overview
The Bourns MF-RG1100-AP-14 is a PTC resettable fuse designed for circuit protection. It features a hold current of 11 A and a trip current of 18.7 A, operating at a maximum voltage of 16 V. The device has a low resistance of 6.2 mΩ and a high interrupt rating of 100 A. It operates within a temperature range of -40°C to +85°C. Dimensions are 17.5 mm in length and 3.00 mm in width, with a height of 26 mm. Power dissipation is rated at 3.7 W. The component utilizes radial leaded mounting.
Feature Summary
- Provides overcurrent protection through self-resetting polymeric positive temperature coefficient technology.
- Features AEC-Q200 qualification for automotive reliability standards.
- Utilizes radial leaded package for through-hole PCB mounting.
Applications
- Automotive electronics circuits requiring AEC-Q200 compliance
- Consumer electronic power input protection
- Industrial instrumentation overcurrent safeguarding
Procurement Notes
Verify the specific suffix AP against the official Bourns datasheet to confirm exact dimensional tolerances and marking codes. Ensure the radial lead configuration matches the target PCB footprint requirements. Confirm that the 11 A hold current aligns with the continuous operational load of the protected circuit to prevent nuisance tripping during normal operation.
Selection Notes
Select this component when high current capacity is required alongside low holding resistance. The 16 V maximum voltage rating limits its use to low-voltage DC applications. Consider the 100 A max current rating for short-circuit protection capabilities. The radial form factor necessitates through-hole assembly processes rather than surface mount techniques.
Part Context
This part belongs to the MF-RG series of resettable fuses from Bourns. The series is characterized by high-current handling capabilities and robust thermal performance. The MF-RG line serves as a reusable alternative to traditional one-time fusible links in power distribution networks.
Replacement Considerations
MF-RG1100-0-14 is a comparable variant within the same series offering similar electrical ratings but potentially different packaging or marking specifications. Verify mechanical dimensions and lead spacing compatibility before substitution.
