The 744229 is a common mode choke from Würth Elektronik, part of the WE-SL2 series. It is designed for common mode noise suppression in power and signal line applications. The component features two windings with an inductance of 6.5 mH per line at 10 kHz and a typical impedance of 18.4 kOhm at 700 kHz. The maximum DC resistance is 0.95 Ω at 20°C, and the rated current is 400 mA with a temperature rise of 40 K. The insulation test voltage is 500 VAC at 50 Hz for 3 seconds, and the rated voltage is 80 V. Leakage inductance is typically 280 nH at 1 MHz.
The device is housed in a horizontal, 4 PC pad surface-mount package with dimensions of 9.2 mm length, 6.0 mm width, and a maximum height of 5.3 mm. The winding style is either bifilar (marked with a dot) or sectional (without a dot). The operating temperature range is -40°C to +125°C, with an ambient temperature limit of -40°C to +85°C for rated current. Storage conditions require temperature below 40°C and relative humidity below 75%.
The 744229 is AEC-Q200 Grade 1 qualified, making it suitable for automotive applications. It is RoHS3 compliant (2011/65/EU & 2015/863), REACH conform or declared, and halogen free per JEDEC JS709B and IEC 61249-2-21. Moisture sensitivity level is MSL 1 (unlimited).
