BWCU00322518900M00

Overview

The BWCU00322518900M00 is a surface-mount common mode choke manufactured by Pulse Electronics. It features a 90 Ohms impedance at 100 MHz and supports a maximum DC current of 1A with a DCR of 80mOhms. The component operates within a temperature range of -40°C to +105°C and utilizes an unshielded design in a compact SMD package.

Feature Summary

• Provides effective common mode noise suppression for high-speed data lines
• Designed specifically for USB 2.0, IEEE1394b, and LVDS applications
• Utilizes an unshielded construction for standard PCB mounting

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 datasheet before integration. Confirm that the 1A current rating and 80mOhms DCR align with your circuit requirements. Ensure the unshielded nature is acceptable for your EMI constraints. Check RoHS compliance status as indicated in manufacturer documentation.

Selection Notes

Select this component when designing for USB 2.0 or FireWire interfaces requiring common mode filtering. Consider the 90 Ohms impedance at 100 MHz for appropriate attenuation characteristics. Evaluate the 1A current handling capability against peak load conditions. The unshielded type may require layout considerations for optimal performance.
