Procurement Notes
Verify the specific suffix AP indicates tape and reel packaging when ordering. Confirm the hold current and trip current ratings match the target circuit requirements against the official datasheet. Ensure the voltage rating is sufficient for the application's maximum operating voltage. Check for AEC-Q200 automotive qualification if used in vehicle systems.
Selection Notes
Select this component based on the required hold current and maximum operating voltage for the protected circuit. Consider the physical footprint constraints of the PCB layout. Evaluate the response time characteristics relative to the downstream components' surge tolerance. Verify compatibility with reflow soldering profiles specified in the manufacturer documentation.
Part Context
This part belongs to the Multifuse RG series, which focuses on high-reliability surface mount protection. The series is engineered for applications requiring fast response times and small board space. It complements other Bourns circuit protection solutions like through-hole fuses and TVS diodes.
Replacement Considerations
Check for direct cross-reference parts within the same series with adjusted current ratings. Verify that any substitute maintains the same voltage rating and package dimensions. Ensure the replacement meets the same environmental compliance standards.
