BWCU00121008900M02

Overview

The BWCU00121008900M02 is an unshielded surface-mount common mode choke from the Pulse Electronics BWCU series. It features a 90 Ohm impedance at 100 MHz with a 20% tolerance. The component supports a maximum DC current of 250 mA and has a maximum DC resistance of 300 mOhms. Designed for PCB mounting, 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, corresponding to the 0504 [1210 Metric] package.

Feature Summary

Provides common mode noise suppression for high-speed data lines
Compact surface-mount design suitable for space-constrained applications
Unshielded construction for standard EMI filtering requirements

Applications

USB 2.0 interface protection
IEEE 1394b (FireWire) signal integrity
LVDS (Low-Voltage Differential Signaling) circuits

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Pulse Electronics documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into production designs.

Selection Notes

Select this component when designing for USB 2.0, IEEE 1394b, or LVDS interfaces requiring compact EMI filtering. Ensure the 250 mA current rating meets the application's peak load requirements and that the 0504 footprint aligns with the PCB layout constraints.

Part Context

This component belongs to the BWCU series of SMD common mode chokes manufactured by Pulse Electronics. It is categorized under Inductors, Chokes & Coils and is specifically engineered for signal line protection in digital communication systems requiring low profile and reliable noise attenuation.

Replacement Considerations

The part number alias CUW11T-900M-N may be referenced in some documentation. Verify electrical equivalence and mechanical compatibility with official substitute lists from Pulse Electronics before implementation.
