Overview
The Bourns SRF0905A-151M is a surface-mount common mode choke from the SRF0905A series, designed for automotive applications. It features an inductance of 150 µH with a tolerance of ±20%. The component has a maximum DC current rating of 800 mA and a maximum DC resistance of 310 mΩ. It operates within a temperature range of -40°C to +105°C and carries AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Ferrite core construction for effective noise suppression
- Surface mount design for automated PCB assembly
Applications
- Automotive power line filtering
- Common mode noise suppression in vehicle electronics
- Signal integrity protection in automotive circuits
Procurement Notes
Verify the specific suffix 'M' indicates the tape and reel packaging configuration as per manufacturer documentation. Confirm that the AEC-Q200 certification applies to this specific variant. Ensure compatibility with standard reflow soldering profiles defined for automotive-grade components. Cross-reference the 3623 package dimensions with the target PCB footprint to prevent mechanical interference during assembly.
Selection Notes
Select this component when automotive-grade reliability is required for common mode noise reduction. The 800 mA current rating suits low-to-medium power signal lines. The 150 µH inductance provides balanced attenuation characteristics. Consider the 3623 package size for space-constrained automotive boards. Verify thermal management requirements against the specified operating temperature range.
Part Context
This part belongs to the Bourns SRF0905A series of shielded surface-mount common mode chokes. The series is engineered specifically for automotive electronic systems requiring robust electromagnetic interference suppression. The SRF0905A designation indicates the physical package dimensions and shielding type within the broader product family.
Replacement Considerations
Direct substitutes include other SRF0905A series variants with matching inductance and current ratings. Verify pinout compatibility and package dimensions before substitution. Check if alternative manufacturers offer AEC-Q200 qualified equivalents with identical electrical specifications.
