Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as cut tape or reel availability prior to ordering. Ensure storage conditions align with manufacturer guidelines to maintain performance integrity.
Selection Notes
Select this component when circuit design requires a low-profile surface-mount solution with moderate holding current. Evaluate thermal dissipation requirements against the specified power dissipation rating. Consider the maximum voltage limit relative to the system's operating potential to ensure adequate safety margins during normal operation.
Part Context
This part belongs to the Bourns Multifuse MF-SM series, which specializes in high-density PPTC resettable fuses. The series is engineered for applications demanding reliable overcurrent protection in compact form factors. It complements other Bourns protection components by offering reusable circuit safeguarding capabilities.
Replacement Considerations
Direct substitutes within the same series include variants with adjusted hold currents such as the MF-SM150/33-2. Verify that alternative parts match the required voltage rating and package dimensions to ensure compatibility with existing board layouts.
