7448229004

Overview

The Würth Elektronik 7448229004 is a WE-CMB HC series common mode choke designed for power line filtering. It features an inductance of 350 µH and supports a maximum DC current rating of 8.5 A. The component exhibits a maximum DC resistance of 7 mΩ (7000 µΩ). It operates within a temperature range of -40°C to +125°C and utilizes through-hole mounting technology.

Feature Summary

• Provides high common mode noise suppression for power lines
• Supports high current handling capabilities up to 8.5 A
• Constructed with low DC resistance for efficient power transmission

Applications

• Power supply input filtering
• EMI suppression in industrial equipment
• Noise reduction in automotive electronics

Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the thermal management requirements align with the specified operating temperature range of -40°C to +125°C. Ensure compatibility with the target PCB layout or wiring harness assembly methods.

Selection Notes

Select this component when high current capacity and significant inductance are required for common mode noise attenuation. The low DC resistance minimizes power loss in high-current applications. Consider the through-hole mounting style for robust mechanical connections in environments subject to vibration.

Part Context

This part belongs to the WE-CMB HC series, which focuses on high-current common mode chokes. The series is engineered for demanding power line applications where space efficiency and thermal stability are critical. It complements other EMI filtering solutions by providing targeted noise suppression at specific frequency bands.

Replacement Considerations

Check for equivalent parts from Würth Elektronik within the WE-CMB series that match the 350 µH inductance and 8.5 A current rating. Verify physical dimensions and terminal types to ensure mechanical interchangeability without redesigning the mounting structure.
