744242510 Description

Short technical summary and product information.

The 744242510 is a surface mount common mode line filter from Würth Elektronik's WE-SLM series. It features a bifilar winding with 2 windings, providing 51 µH inductance at 100 kHz and a typical impedance of 2.5 kΩ at 25 MHz. The component is rated for a maximum current of 400 mA and a maximum DC resistance of 0.32 Ω. It supports a rated voltage of 80 VDC (42 VAC) and has an insulation test voltage of 250 VAC.

 

This common mode choke is designed for suppressing common mode noise on signal lines, making it suitable for interfaces such as USB, CAN, FireWire, and general sensor lines. It can also be used in power supply systems and data lines. The operating temperature range is -40°C to +125°C, with an ambient temperature range of -40°C to +85°C for rated current.

 

The component is housed in a horizontal surface mount package with 4 flat leads, measuring 6.00 mm x 3.30 mm x 3.50 mm. It is RoHS3 compliant, REACH unaffected, halogen free, and has a moisture sensitivity level of 1 (unlimited). The flammability rating is UL 94 V-0.
