SRF2012-161Y

Overview

The Bourns SRF2012-161Y is a surface-mount common mode chip inductor from the SRF2012A series. It features a ferrite core and four terminals for dual-line filtering. The component supports a maximum DC current of 300 mA with a maximum DC resistance of 500 mΩ ±25%. Its impedance is 160 Ohms at 100 MHz, and it operates within a temperature range of -55°C to 125°C. The physical dimensions are 2.0 mm x 1.2 mm x 1.2 mm. It complies with RoHS standards.

Feature Summary

• Dual-line common mode noise suppression using ferrite core technology
• Compact surface-mount design suitable for space-constrained PCB layouts
• Wide operating temperature range for diverse environmental conditions

Applications

• High-speed data line filtering
• USB interface noise suppression
• HDMI signal integrity protection

Procurement Notes

Verify the specific suffix 'YA' or 'Y' against the manufacturer's current datasheet to confirm impedance tolerance and packaging details. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the part number with official Bourns databases to avoid obsolete stock variations.

Selection Notes

Select this component when dual-line EMI suppression is required for low-current digital interfaces. The 300 mA rating suits data lines rather than power delivery. Verify that the 160 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Confirm mechanical fit within the 2012 package footprint constraints.

Part Context

This part belongs to the Bourns SRF2012A series of common mode chokes. These components are designed for high-frequency noise attenuation in compact electronic devices. The series utilizes multilayer ceramic and ferrite technologies to provide reliable performance in small form factors.

Replacement Considerations

Check for direct substitutes within the SRF2012 series with matching impedance values. Verify pin compatibility and thermal characteristics before substitution.
