Overview
The Würth Elektronik 784231371 is a surface-mount common mode filter choke from the WE-CNSA series, designed for data line protection. It features an inductance of 0.478 µH and a rated current of 280 mA. The component exhibits a DC resistance of 450 mΩ and provides an impedance of 370 Ω at 100 MHz. Packaged in an 0805 (2012 metric) footprint measuring 2 mm x 1.2 mm x 1.2 mm, it is AEC-Q200 qualified for automotive reliability.
Feature Summary
- Current compensated design for effective noise suppression on differential data lines
- AEC-Q200 qualification ensuring suitability for automotive electronic applications
- Compact 0805 surface-mount package optimized for space-constrained PCB layouts
Applications
- Automotive infotainment systems
- High-speed data interface protection
- USB and other differential signal line filtering
Procurement Notes
Verify the specific ordering code against the manufacturer's latest datasheet to ensure correct impedance and tolerance specifications. Confirm that the AEC-Q200 qualification status meets your project's automotive reliability requirements. Check for any recent updates to the RoHS compliance documentation before finalizing procurement orders.
Selection Notes
Select this component when space is limited due to its small 0805 footprint. Ensure the 280 mA current rating aligns with the maximum operating current of the protected circuit. The 370 Ω impedance at 100 MHz makes it suitable for high-frequency noise attenuation in sensitive digital communication interfaces.
Part Context
This part belongs to the WE-CNSA series of common mode chokes from Würth Elektronik. These components are engineered specifically for suppressing electromagnetic interference in compact electronic designs. The series offers various inductance values while maintaining consistent physical dimensions for standardized board integration.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference impedance curves and current ratings carefully when evaluating generic equivalents.
