Procurement Notes
Verify the specific ordering suffix against the official Bourns datasheet to ensure correct packaging configuration. Confirm that the component meets AEC-Q200 requirements if intended for automotive use. Cross-reference the maximum operating temperature and voltage ratings with the target application's electrical specifications prior to integration.
Selection Notes
Select this component when an 11A hold current and 16V maximum voltage rating are required for automotive-grade protection. Ensure the application current remains below the 11A threshold under all operating conditions. Verify that the radial lead spacing matches the PCB layout constraints.
Part Context
This part belongs to the Bourns Multifuse MF-RG series, which provides resettable overcurrent protection solutions. The series is specifically engineered for automotive applications, offering reliable performance in harsh environments while maintaining compliance with strict industry quality standards such as AEC-Q200.
Replacement Considerations
Consult the official Bourns replacement guide for direct substitutes. Verify that any alternative maintains identical AEC-Q200 certification and radial lead dimensions.
