Common-mode choke coils suppress noise in compact industrial and consumer designs

The DLW21SN_HQ2 series of chip common-mode choke coils features a compact 2.0mm x 1.2mm footprint while providing highly effective suppression of noise in high-speed interfaces using differential signal lines.

These Murata common-mode choke coils address the rising demand for more compact components for electronic systems in industrial robotics, audio-visual systems and communication modules which often make use of differential interfaces that require higher current. The DLW21SN_HQ2 series can handle rated currents up to 320mA supporting both power and signal lines in various circuit configurations.

The coils offer common-mode impedance values of 67Ω, 90Ω, and 120Ω at 100MHz featuring a rated voltage of 20V dc and a withstanding voltage of 50V dc. The maximum dc resistance ranges from 0.31Ω to 0.41Ω.
