Murata launches common mode choke coil

With an increasing sophistication in the automotive market, such as trends like autonomous driving and the use of cameras situated around the vehicle, the need to have a fast and reliable differential network to transport large amounts of data is essential.

Murata has achieved the characteristics required for these networking applications by controlling the balance of the electrostatic stray capacitance between wires. Techniques used have included expertise gained from the methods employed in winding common mode chokes for other high speed network applications.

The DLW43MH measures 4.5 x 3.2 x 2.7 mm and achieves a common mode inductance of 200 uH when measured at 100 kHz. The rated voltage is 20 V, has a rated current of up to 100 mA and a maximum DC resistance of 4.5 ohms.
