Overview
The MF-SM250-2-006 is a surface-mount PTC resettable fuse from Bourns Inc., designed for circuit protection against overcurrent and short circuits. It features a maximum voltage rating of 15V and a trip current of 2.5A. The component complies with AEC-Q200 standards, indicating suitability for automotive applications. It utilizes a 2-SMD package with dimensions of 0.344 inches in length and 0.264 inches in width (8.75mm x 6.71mm).
Feature Summary
- Provides automatic resettable overcurrent protection without manual replacement.
- Complies with AEC-Q200 qualification standards for automotive reliability.
- Utilizes a compact surface-mount design for automated assembly integration.
Applications
- Consumer electronics requiring short-circuit prevention
- Automotive electronic circuits meeting AEC-Q200 standards
Procurement Notes
Verify the specific datasheet version to confirm electrical parameters such as hold current and trip current match system requirements. Ensure the AEC-Q200 compliance status aligns with target application regulations. Confirm RoHS compliance status for environmental adherence. Validate package dimensions against PCB footprint specifications prior to procurement.
Selection Notes
Select this component when a low-voltage, high-current resettable fuse is required for space-constrained designs. Consider the 15V maximum voltage limit and 2.5A trip current relative to the protected circuit's operating conditions. Evaluate the thermal environment to ensure proper derating. Compare physical dimensions against available board space constraints.
Part Context
This part belongs to the MF-SM series of multifuse devices from Bourns Inc. These components are polyswitch resettable fuses intended for circuit protection. The series offers various current ratings and package options to accommodate different power levels and form factors in modern electronic assemblies.
Replacement Considerations
The LR4-190SLF is identified as a comparable alternative from Littelfuse Inc. Verify that the substitute meets or exceeds the 15V rating and provides adequate current protection characteristics for the specific application requirements.
