744242330 Description

Short technical summary and product information.

The Würth Elektronik 744242330 is a surface-mount common mode line filter from the WE-SLM series. It features a bifilar winding with two windings, providing an inductance of 33µH (measured at 10 kHz/100 mV) with a tolerance of +50%/-30%. The maximum impedance is 2kΩ typical at 50 MHz, and the DC resistance is 270mΩ maximum at 20°C. Rated for 80V DC (42V AC) and 300mA current (ΔT=40K), this component is designed for common mode noise suppression in power supply systems, data lines, USB, CAN, and FireWire interfaces.

 

The filter operates over a temperature range of -40°C to +125°C and meets climatic category 40/125/21. It is housed in a horizontal, 4 flat lead package measuring 6.0mm x 3.3mm x 3.5mm, suitable for surface mount assembly. The component is RoHS3 compliant, REACH unaffected, halogen-free, and has a flammability rating of UL 94 V-0. Moisture sensitivity level is MSL 1 (unlimited).
