Overview
The Bourns SRF3216A-161Y is a surface-mount common mode choke from the SRF3216A series. It features an inductance of 160 µH with a tolerance of ±25%. The component supports a maximum DC current of 350 mA and has a maximum DC resistance (DCR) of 400 mΩ. It operates within a temperature range of -40°C to +125°C. The device utilizes a ferrite core, measures 3.2 mm x 1.6 mm x 2.0 mm, and carries AEC-Q200 automotive qualification.
Feature Summary
- Provides common mode noise suppression for two-line circuits
- Constructed with a molded ferrite core structure
- Qualified for automotive applications under AEC-Q200 standards
Applications
- Automotive electronic circuit protection
- Common mode noise filtering in data lines
- Signal integrity enhancement in compact PCB designs
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm terminal plating and packaging specifications. Ensure the selected variant matches the required AEC-Q200 certification if used in automotive contexts. Cross-reference the impedance value at the target frequency to validate performance requirements before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require a 3216 footprint for common mode filtering. The 350 mA rating suits low-current signal lines rather than high-power supply rails. Consider the 400 mΩ DCR impact on voltage drop. Verify that the 160 µH inductance provides sufficient attenuation at the specific interference frequencies present in the application environment.
Part Context
This part belongs to the Bourns SRF3216A series of surface mount common mode chokes. The series offers various inductance values within a standardized 3216 metric package size. These components are designed for automated assembly processes and provide reliable noise suppression in environments requiring automotive-grade reliability and compact form factors.
Replacement Considerations
Direct substitutes include other SRF3216A series variants with matching electrical characteristics. Verify pin compatibility and physical dimensions when considering alternative manufacturers. Ensure any replacement maintains the same AEC-Q200 qualification status if automotive compliance is mandatory.
