MF-SM075-2

Overview

The Bourns MF-SM075-2 is a surface-mount PTC resettable fuse from the MF-SM series, designed for overcurrent protection in low-voltage circuits. It features a hold current of 0.75 A and a trip current of 1.5 A, with a maximum voltage rating of 60 VDC. The device exhibits a typical resistance of 0.23 Ohms and can withstand a maximum fault current of 10 A. Packaged in an SMD/SMT format, it operates within a temperature range of -40°C to +85°C.

Feature Summary

Provides automatic circuit recovery after fault conditions without manual replacement
Offers high reliability through polymer positive temperature coefficient technology
Designed for compact surface-mount integration in space-constrained applications

Applications

Portable electronic devices requiring overcurrent protection
Consumer electronics circuit boards
Battery pack protection systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Bourns documentation. Confirm that the specific suffix matches the required electrical ratings. Ensure compliance with RoHS directives if applicable to the target assembly. Request updated datasheets directly from authorized distributors to validate current manufacturing status and technical specifications before finalizing procurement orders.

Selection Notes

Select this component when a 60 VDC rating and 0.75 A hold current are required for surface-mount designs. Consider the 0.23 Ohm resistance impact on circuit efficiency. Evaluate the 10 A maximum fault current capability against potential surge scenarios. Ensure the operating temperature range aligns with the environmental conditions of the end application.

Part Context

This component belongs to the MF-SM series of PTC resettable fuses, which are engineered for general-purpose circuit protection. The series provides various hold current options within a standardized surface-mount footprint, allowing designers to scale protection levels while maintaining consistent board layout dimensions across different product variants.
