The Würth Elektronik 744831034090 is a common mode power line choke from the WE-CMB HV series. It features two windings with a nominal inductance of 3.4 mH (±30%) measured at 10 kHz and 0.1 mA. The component is rated for a maximum current of 9 A at 70 °C ambient temperature, with a maximum DC resistance of 27 mΩ at 20 °C.
This choke is designed for power line filtering applications and supports a maximum rated voltage of 760 V AC at 50 Hz. The insulation test voltage is 3000 V AC at 50 Hz, 5 mA for 2 seconds. The component operates over a temperature range of -40 °C to +125 °C, with a maximum temperature rise of 55 K.
The component is housed in a vertical, 4 PC pad package with through hole mounting and PC pin termination. Body dimensions are 44.5 mm diameter and 28.0 mm width, with a maximum height of 44.5 mm. Due to its heavy weight, the datasheet recommends fixing the component to the PCB with two self-tapping screws.
The 744831034090 is RoHS compliant, REACH conform, and halogen free. It has a moisture sensitivity level of 1, indicating unlimited floor life. The component is suitable for general electronic equipment applications.
