SRF2012-181YA

Overview

The SRF2012-181YA is a surface-mount common mode choke manufactured by Bourns Inc. It features a ferrite core and provides an impedance of 180 Ohms at 100 MHz. The component supports a maximum current rating of 350 mA with a DC resistance of 350 mOhm. It operates within a temperature range of -40°C to 125°C and carries AEC-Q200 automotive qualification.

Feature Summary

Provides high impedance for common mode noise suppression in two-line configurations
AEC-Q200 qualified for automotive reliability standards
RoHS compliant and halogen-free construction

Applications

Automotive data bus line filtering
High-speed signal interface protection
Common mode noise reduction in compact electronic modules

Procurement Notes

Verify the specific suffix against official Bourns documentation to confirm exact electrical tolerances and packaging specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the delivered parts match the AEC-Q200 qualification status required for your application.

Selection Notes

Select this component when designing circuits requiring low-profile surface-mount common mode filtering with strict automotive reliability requirements. The 180 Ohm impedance at 100 MHz suits high-frequency noise attenuation. Verify that the 350 mA current rating meets the operational load without exceeding thermal limits defined by the 350 mOhm DC resistance.

Part Context

This part belongs to the SRF2012 series of common mode chokes from Bourns. The series is characterized by small surface-mount footprints designed for space-constrained applications. These components utilize ferrite cores to achieve high impedance values while maintaining low DC resistance for efficient signal transmission.

Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Cross-referencing requires matching impedance, current rating, and package dimensions.
