7446221010

Overview

The Würth Elektronik 7446221010 is a through-hole common mode choke from the WE-LF Type MV series. It features an inductance of 10 mH at 10 kHz and supports a maximum DC current of 1.3 A per line. The component has a DC resistance of 250 mOhms per line and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective common mode noise suppression for power lines
• Designed for through-hole PCB mounting applications
• Utilizes a robust construction suitable for mains power line filtering

Applications

• Mains power line EMI filtering
• Power supply input stages
• General purpose noise suppression in electronic equipment

Procurement Notes

Verify the specific voltage rating and physical dimensions against the official datasheet before integration. Confirm that the through-hole footprint matches the target PCB layout. Ensure the thermal management plan accommodates the operating temperature range up to 125°C under full load conditions.

Selection Notes

Select this component when designing circuits requiring high inductance values for low-frequency noise attenuation. The 1.3 A current rating makes it suitable for moderate power applications. Consider the through-hole requirement as surface mount alternatives may not be available in this specific series configuration.

Part Context
