MF-FSML150/8-2

Ptc Resettable Fuses Overview

The MF-FSML150/8-2 is a surface-mount polymeric PTC resettable fuse manufactured by Bourns Inc. It features an 0603 (1608 Metric) package with concave geometry, designed for circuit protection applications. The device has a holding current of 1.5 A and a tripping current of 3 A at a maximum voltage of 8 VDC. Initial resistance is typically low, ensuring minimal impact on normal operation. The component operates within a temperature range of -40°C to +85°C and provides reliable overcurrent protection in compact electronic designs.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient technology for automatic reset capability after fault clearance
• Concave surface-mount design optimized for automated pick-and-place assembly processes
• Compact 0603 footprint suitable for high-density printed circuit board layouts
• Fast response time to overcurrent conditions to protect sensitive downstream components

Ptc Resettable Fuses Applications

• Portable consumer electronics such as mobile phones and tablets
• USB peripheral devices and data cables
• Battery packs and power management circuits
• Automotive infotainment and sensor modules

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix codes against official Bourns documentation to confirm electrical ratings and packaging details. Ensure that the procurement channel provides genuine components with traceable origin. Check for RoHS compliance status if required by regulatory standards. Confirm that the supplier offers appropriate handling guidelines for ESD-sensitive polymer devices during storage and installation.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require an 0603 form factor with low profile characteristics. The 8V rating limits suitability to low-voltage digital logic and communication interfaces rather than power lines. Evaluate the thermal environment to ensure the operating temperature range accommodates ambient conditions. Consider the trip time requirements relative to the protected circuit's tolerance for transient currents.

Ptc Resettable Fuses Part Context

This part belongs to Bourns' MF-FSML series of surface-mount resettable fuses. The series utilizes proprietary polymer composite materials to achieve rapid switching between low-resistance and high-resistance states. The FSML designation indicates a specific size code and voltage class within the broader portfolio of polymeric circuit protection devices offered by the manufacturer.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 0603 package, 1.5A holding current, and 8V maximum voltage specifications. Verify that alternative parts maintain similar initial resistance and trip time characteristics to ensure circuit compatibility. Cross-reference mechanical dimensions to confirm fit within the existing PCB footprint without interference.
