The 7446630039 is a surface mount common mode line choke from Würth Elektronik’s WE-LF SMD series. It provides 39 mH inductance (measured at 10 kHz, 0.1 mA) with ±30% tolerance and a typical leakage inductance of 345 µH at 100 kHz. The component is rated for a maximum DC resistance of 1.7 Ω and a continuous current of 0.55 A at 70 °C.
The choke is designed for power line common mode filtering. It has a rated AC voltage of 250 V at 50 Hz and passes a 1500 V AC insulation test voltage. Maximum temperature rise is 55 K, and the operating temperature range extends from -40 °C to +125 °C, supporting use in demanding power electronics environments.
Mechanically, the choke uses a horizontal, 4 PC pad surface mount package measuring 23.3 mm x 18.5 mm x 11.5 mm. It is moisture sensitivity level 1 (MSL 1), and is RoHS compliant, REACH conform or declared, and halogen free in accordance with JEDEC JS709B.
