744233900

Overview

The Würth Elektronik 744233900 is a surface-mount common mode choke from the WE-CNSW HF series, designed for signal line filtering. It features two lines with an impedance of 90 Ohms at 100 MHz and a maximum DC resistance of 300 milliohms. The component supports a rated current of 280 mA and operates within a temperature range of -40°C to 105°C. It holds AEC-Q200 certification and utilizes a compact 0805 (2.00mm x 1.20mm) footprint.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High impedance performance at 100 MHz for effective noise suppression
• Compact surface-mount design suitable for space-constrained applications

Applications

• USB 3.0 interface signal line filtering
• High-speed data bus EMI suppression
