BWCU00201212371M02

Overview

The BWCU00201212371M02 is an unshielded surface-mount common mode choke from the Pulse Electronics BWCU series. It features a 370 Ohms impedance at 100 MHz with a 20% tolerance. The component supports a maximum DC current of 280 mA and has a maximum DC resistance of 450 mOhms. Rated for 50 VDC, it operates within a temperature range of -40°C to +105°C. The physical dimensions are 2.05 mm in length, 1.25 mm in width, and 1.2 mm in height.

Feature Summary

Provides common mode noise suppression for high-speed data lines
Designed specifically for USB 2.0, IEEE1394b, and LVDS applications
Utilizes a compact SMD package for efficient PCB space utilization

Applications

USB 2.0 interface protection
IEEE1394b (FireWire) signal filtering
LVDS data line noise reduction

Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 280 mA current rating and 450 mOhms DCR meet your circuit requirements. Ensure the 50 VDC voltage rating is sufficient for your application environment. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when designing circuits requiring common mode filtering for USB or FireWire interfaces. The 370 Ohms impedance is suitable for suppressing high-frequency noise without significantly affecting signal integrity. Consider the 280 mA current limit when sizing power delivery paths. The small footprint makes it ideal for dense board layouts where space is constrained.
