Overview
The Bourns SRF2012-161YA is a two-line common mode choke from the SRF2012A series, designed for surface mount applications. It provides an impedance of 160 Ohms at 100 MHz with a tolerance of ±25%. The component supports a current rating of 350 mA and features a DC resistance (DCR) of 0.35 Ohms maximum. These specifications enable effective noise attenuation in high-speed signal lines.
Feature Summary
- Designed to attenuate unwanted noise frequencies in high-speed signal transmission paths
- Constructed as a two-line common mode choke for surface mount integration
- Engineered for compatibility with sensitive digital interface standards
Applications
- USB 2.0 signal line protection
- IEEE 1394 data bus filtering
- LVDS interface noise suppression
Procurement Notes
Verify the complete part number including the suffix YA against official Bourns documentation to ensure correct impedance and packaging specifications. Confirm that the required current rating of 350 mA aligns with the target circuit design before procurement. Cross-reference the datasheet for specific reel quantities and handling instructions.
Selection Notes
Select this component when designing circuits requiring common mode noise reduction for USB 2.0, IEEE 1394, or LVDS interfaces. Ensure the operating current does not exceed the 350 mA rating to maintain performance. Verify that the 160 Ohm impedance at 100 MHz meets the specific frequency requirements of the application.
Part Context
This component belongs to the Bourns SRF2012A series of common mode chip inductors. The series offers various impedance values tailored for different signal integrity needs. The SRF2012-161YA specifically targets applications requiring moderate noise suppression capabilities within a compact surface mount footprint.
Replacement Considerations
Consult the official Bourns SRF2012A series datasheet for alternative part numbers with similar electrical characteristics. Verify pinout compatibility and physical dimensions before substituting any other manufacturer's components.
