MF-SM150/33-2

Overview

The Bourns MF-SM150/33-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the MF-SM series. It features a hold current of 1.5 A and a trip current of 3 A, with a maximum voltage rating of 33 VDC. The device supports a maximum fault current of 40 A and has a typical resistance of 230 mΩ. Designed for operation between -40°C and +85°C, it utilizes a 2920 package.

Feature Summary

Provides automatic circuit protection through self-resetting PPTC technology
Designed for surface-mount assembly on printed circuit boards
Offers high fault current capability up to 40 A

Applications

Portable electronic devices
Automotive electronics
Telecommunications equipment

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MF-SM150/33-2 with official Bourns documentation. Confirm RoHS compliance status and specific packaging details such as reel or cut tape configuration directly with authorized distributors. Ensure the supplier provides valid traceability records to guarantee product integrity and adherence to specified electrical parameters.

Selection Notes

Select this component when a compact surface-mount solution is required for overcurrent protection in low-voltage circuits. The 1.5 A hold current and 33 VDC rating suit applications where space is limited but reliable thermal protection is necessary. Consider the 2920 package dimensions for PCB layout constraints and ensure the operating temperature range aligns with the system environment.

Part Context

This device belongs to the Bourns MF-SM series of high-density SMD resettable fuses. The series is engineered for modern electronics requiring small footprints and robust protection. The MF-SM line offers various current and voltage ratings to accommodate diverse circuit requirements while maintaining consistent performance characteristics across the family.

Replacement Considerations

Consult official Bourns substitution guides for verified alternatives. Do not assume compatibility based solely on similar package sizes or nominal ratings without verifying electrical specifications against the original datasheet.
