Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm exact electrical tolerances and physical dimensions. Ensure the selected variant matches the required PCB footprint and thermal dissipation capabilities for the target application environment.
Selection Notes
Select this component when a low-profile resettable fuse is required for 30V DC circuits. Evaluate the ambient operating temperature to ensure the holding current remains sufficient under worst-case conditions. Confirm that the trip time characteristics align with the sensitivity requirements of the protected downstream components.
Part Context
This part belongs to the Bourns MFR series of self-recovery fuses, which are PPTC devices used for circuit protection. The series provides various current ratings and package options to suit different industrial and consumer electronics applications requiring reliable overcurrent defense.
Replacement Considerations
The MF-R160-0-012 is a documented variant within the same product family. Verify dimensional compatibility and electrical parameter equivalence before substitution.
