BWCU00321619261M02

Overview

The BWCU00321619261M02 is a two-line surface mount common mode filter choke manufactured by Pulse Electronics. It features an impedance of 260 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 310 mA. The component has a maximum DC resistance (DCR) of 500 mOhms. It operates within a temperature range of -40°C to +105°C and utilizes an unshielded design. The physical dimensions are 3.2 mm in length, 1.6 mm in width, and 1.9 mm in height.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Designed for high-density surface mount PCB integration
• Utilizes ferrite core material for effective EMI filtering

Applications

• USB 2.0 interface protection
• IEEE 1394b data bus filtering
• LVDS signal line conditioning

Procurement Notes

Verify the specific manufacturer designation, as sourcing records indicate potential association with YAGEO or Pulse Electronics. Confirm RoHS compliance status and ensure the ordering suffix matches the required impedance tolerance. Validate that the package type aligns with automated pick-and-place requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring 260 Ohms of common mode impedance at 100 MHz. Ensure the application current does not exceed 310 mA to prevent saturation. Verify that the 3.2 x 1.6 mm footprint fits the board layout constraints and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the BWCU series of SMD common mode chokes from Pulse Electronics. These components are engineered for compact electronic designs where space is limited.
