BWCU00160811121M02

Overview

The BWCU00160811121M02 is a two-line common mode choke manufactured by Pulse Electronics. It features an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 160 mOhms. It utilizes a surface mount package with dimensions of 1.6 mm length, 0.8 mm width, and 1.1 mm height.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Designed for high-speed data transmission applications
• Utilizes a compact surface mount footprint

Applications

• USB 2.0 interface protection
• IEEE 1394b (FireWire) line filtering
• LVDS signal integrity enhancement

Procurement Notes

Verify the specific manufacturer designation when sourcing, as some listings may reference Chilisin as the original producer while Pulse Electronics distributes the component. Confirm the impedance value of 120 Ohms at 100 MHz matches the design requirements. Ensure the 500 mA current rating is sufficient for the target application to prevent saturation or excessive heating during operation.

Selection Notes

Select this component for applications requiring common mode filtering on high-speed serial interfaces. The 120 Ohm impedance offers effective attenuation for typical EMI frequencies in digital communication lines. The low DC resistance minimizes signal loss and power dissipation in the data path. Consider the physical dimensions for PCB layout constraints in dense assemblies.

Part Context

This component belongs to the category of passive electronic filters used for electromagnetic interference suppression. Common mode chokes are essential for maintaining signal integrity in high-speed digital circuits by attenuating noise that appears in phase on both signal lines relative to ground.
