Overview
The Bourns MF-SM013/250V-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a hold current of 0.13 A and a maximum voltage rating of 60 VDC, with a trip current of 0.26 A. The device exhibits a typical resistance of 6.5 ohms and a maximum resistance of 20 ohms at room temperature. It supports a maximum fault current of 3 A and operates within a temperature range of -40°C to +85°C. The component measures 7.4 mm in length, 6.6 mm in width, and 3.2 mm in height.
Feature Summary
- Provides automatic circuit interruption and manual reset capability upon cooling following overcurrent events
- Utilizes polymer technology to deliver high cycle life reliability without requiring replacement after tripping
- Offers compact vertical surface-mount packaging suitable for automated assembly processes
Applications
- Portable electronic devices requiring overcurrent protection
- Consumer electronics circuits needing compact resettable fuses
- Automotive infotainment and control modules
- Industrial equipment power supply inputs
Procurement Notes
Verify the specific suffix designation against the manufacturer datasheet to confirm package orientation and tape/reel specifications. Ensure the selected variant matches the required hold current and voltage ratings for the target application circuit. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.
Selection Notes
Select this component based on the 0.13 A hold current requirement and 60 VDC maximum voltage constraint. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range. Consider the 3 A maximum fault current capability relative to potential short-circuit conditions in the protected circuit.
Part Context
This part belongs to the MF-SM series of miniature surface-mount PPTC resettable fuses from Bourns. The series provides protection for low-current applications where space constraints prevent the use of traditional axial or radial fuses. These components serve as reusable alternatives to single-use fusible links in modern printed circuit board designs.
Replacement Considerations
Consult the official Bourns substitution guide for verified cross-reference part numbers. Verify that any alternative maintains identical electrical parameters including hold current, voltage rating, and resistance values.
