744227S Description

Short technical summary and product information.

The 744227S is a WE-SL2 SMT common mode line filter manufactured by Würth Elektronik. It is designed for power and signal line common mode noise suppression in automotive and industrial applications. The component is qualified to AEC-Q200 Grade 1, ensuring reliability in harsh environments.

 

Key electrical specifications include an inductance of 51 µH (measured at 1 kHz, 100 mV) with ±30% tolerance, a maximum DC resistance of 160 mΩ, and a rated current of 1 A. The impedance reaches 5.5 kΩ typical at 30 MHz. The component also features a leakage inductance of 3150 nH typical and an insulation test voltage of 500 V AC.

 

The filter is housed in a horizontal, 4 PC pad surface mount package with dimensions of 9.2 mm length, 6.0 mm width, and 5.3 mm maximum height. The lead spacing is 2.54 mm. Operating temperature range is -40°C to +125°C, making it suitable for automotive underhood applications.

 

The component is RoHS compliant, REACH conform, and halogen free. It is designed for use in DC/DC converters, motor drives, and signal line filtering where common mode noise suppression is required.
