BWCC00201208261M02

Overview

The BWCC00201208261M02 is a two-line surface mount common mode 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 700 mA. The component has a maximum DC resistance of 600 mOhms and operates within a temperature range of -40°C to +105°C. Its physical dimensions are 2.0 mm in length, 1.2 mm in width, and 0.8 mm in height.

Feature Summary

• Provides common mode noise suppression for high-speed data lines
• Designed for surface mount PCB integration
• Supports dual-line signal transmission

Applications

• USB 2.0 interface protection
• IEEE 1394 (FireWire) signal filtering
• LVDS data line noise reduction
• HDMI 1.4 signal integrity maintenance

Procurement Notes

Verify the specific impedance value against design requirements, as distributor listings may vary between 260 Ohms and other values. Confirm the package type is Tape & Reel or Cut Tape as specified. Ensure the thermal rating meets the operational environment limits of -40°C to +105°C before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring common mode rejection for USB, FireWire, LVDS, or HDMI interfaces. The 700 mA current rating suits low-power digital signaling applications. Verify that the 260 Ohm impedance aligns with the target noise frequencies and that the 0.8 mm height fits the board clearance constraints.

Part Context

This part belongs to the Chilisin series of RF inductors and chokes produced under license or partnership with Pulse Electronics. It falls under the category of SMD Common Mode Chokes used primarily for electromagnetic interference suppression in consumer electronics and computer peripherals.

Replacement Considerations

Check for direct substitutes within the same series or equivalent impedance ratings from other manufacturers. Ensure replacement parts match the 2.0x1.2x0.8 mm footprint and 700 mA current handling capability.
