BWCU00201212161M02

Overview

The BWCU00201212161M02 is a surface-mount common mode choke manufactured by Pulse Electronics. It features an impedance of 160 Ohms at 100 MHz with a tolerance of 20%. The component supports a maximum DC current of 350 mA and has a maximum DC resistance of 350 mOhms. Its physical dimensions are 2.05 mm in length, 1.25 mm in width, and 1.2 mm in height. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• Designed for noise suppression in high-speed digital interfaces
• Compact surface-mount package suitable for space-constrained PCB layouts
• Unshielded construction for standard electromagnetic interference mitigation

Applications

• USB 2.0 data line protection
• IEEE 1394b interface filtering
• LVDS signal integrity enhancement

Procurement Notes

Verify the specific impedance value against official datasheets, as sources vary between 120 Ohms and 160 Ohms. Confirm the manufacturer designation, noting references to both Pulse Electronics and Chilisin. Ensure the ordering suffix matches the required packaging format before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring common mode noise reduction for USB or FireWire interfaces. Evaluate the 350 mA current rating against peak signal requirements. Consider the unshielded nature if strict EMI compliance is needed without additional shielding measures.
