BWCU00121008201M02

Overview

The BWCU00121008201M02 is a surface-mount common mode filter choke manufactured by Pulse Electronics. It features an impedance of 200 Ohms at a test frequency of 100 MHz with a tolerance of 20%. The component supports a maximum DC current of 120 mA and has a maximum DC resistance of 800 mOhms. It operates within a temperature range of -40°C to +105°C. The physical dimensions are 1.25 mm in length, 1 mm in width, and 0.8 mm in height.

Feature Summary

• Designed for noise suppression in high-speed digital interfaces
• Suitable for USB 2.0, IEEE1394b, and LVDS applications
• Surface mount construction for automated PCB assembly

Applications

• USB 2.0 data line protection
• IEEE1394b interface filtering
• LVDS signal integrity enhancement

Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 120 mA current rating meets the design requirements. Ensure the 1.25 x 1 x 0.8 mm footprint matches the PCB layout. Check RoHS compliance status as indicated in the product documentation.

Selection Notes

Select this component for applications requiring common mode noise reduction in compact form factors. The 200 Ohm impedance provides effective attenuation at 100 MHz. Consider the 120 mA current limit when designing power delivery paths. The unshielded design may require careful layout considerations for EMI management.
