Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Bourns documentation. Confirm that the specific suffix 'NL' corresponds to the narrow long lead configuration required for your design. Ensure environmental ratings meet operational temperature requirements before finalizing procurement orders.
Selection Notes
Select this component when low voltage circuits require resettable protection with specific axial lead geometry. Evaluate hold current and trip current thresholds against normal operating loads to ensure reliable performance. Consider physical dimensions and mounting style compatibility with the target PCB or assembly constraints during the design phase.
Part Context
This part belongs to the Bourns Multifuse MF-SVS series of self-resetting fuses. These components utilize polymer positive temperature coefficient technology to provide robust overcurrent protection. The series is widely utilized in consumer electronics and industrial applications where reliable, reusable circuit protection is essential for system integrity.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the MF-SVS family. Verify electrical parameters such as hold current, trip current, and voltage ratings match application requirements. Ensure physical dimensions and lead configurations are compatible with existing board layouts before implementing any substitute parts.
