The Würth Elektronik 7446223001 is a WE-LF common mode power line choke designed for suppressing electromagnetic interference in power supply lines. It features a nominal inductance of 1 mH measured at 10 kHz with 50 mV test signal, and a maximum DC resistance of 40 milliohms at 20°C. The component is rated for a maximum current of 3 A at 70°C and a maximum voltage of 250 V AC at 50 Hz.
The choke comes in a vertical through-hole package with four PC pins, measuring 23.50 mm length, 16.00 mm width, and 25.50 mm height. It operates over a temperature range of -40°C to +125°C with a maximum temperature rise of less than 55 K. The component is RoHS compliant, REACH conform, halogen-free, and has an MSL of 1.
Typical applications include power supply input filters, switched-mode power supplies, and other electronic equipment requiring common mode noise attenuation in AC or DC power lines. Designers should note that inductance tolerance is ±30% and the storage conditions recommend below 40°C and 75% relative humidity.
