SRF2012A-161YA

Overview

The Bourns SRF2012A-161YA is a two-line surface mount common mode choke designed for signal line protection. It features an inductance of 160 Ohms at 100 MHz and supports a maximum DC current rating of 350 mA. The component exhibits a maximum DC resistance (DCR) of 350 mOhm per line. It operates within a temperature range of -40°C to +125°C and complies with the AEC-Q200 automotive qualification standard.

Feature Summary

• Provides common mode noise suppression for high-speed data lines
• Automotive-grade reliability compliant with AEC-Q200 standards
• Compact surface mount footprint suitable for space-constrained designs

Applications

• USB interface circuits
• High-speed serial data transmission lines
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix 'YA' against the manufacturer's official datasheet to confirm exact impedance and tolerance specifications. Ensure the selected variant meets the required AEC-Q200 qualification level if used in automotive applications. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when designing for high-frequency common mode noise attenuation in compact form factors. The 350 mA current rating suits low-power signal lines rather than power delivery paths. Consider the 160 Ohm impedance value at 100 MHz to ensure effective filtering for the target frequency spectrum without excessive signal degradation.

Part Context

This part belongs to the SRF2012A series of multi-layer chip inductors from Bourns. The series utilizes ferrite core materials to achieve high impedance characteristics in a small outline package. These components are engineered for surface mount technology, offering consistent performance across industrial and automotive environments.

Replacement Considerations

Consult the official Bourns replacement guide for direct equivalents. Verify that any substitute maintains the same 160 Ohm impedance at 100 MHz and 350 mA current rating. Ensure the alternative component also holds AEC-Q200 certification if automotive compliance is mandatory.
