Common-mode choke coils reduce noise in compact automotive designs
The DLM11CN_HH2 series of common-mode choke coils from Murata provides effective noise suppression for high-speed differential signal lines in compact automotive powertrain and safety equipment.
The DLM11CN_HH2 series of surface-mount chip common-mode choke coils features a compact 1.25mm x 1.0mm footprint while providing strong noise suppression in high-speed interfaces using differential signal lines.
These Murata common-mode choke coils address increasing demand for more compact components for automotive electronic control units (ECUs), safety sensors, and infotainment systems which often make use of differential interfaces. The DLM11CN_HH2 series can handle rated currents up to 100mA supporting signal lines in various circuit configurations
The coils offer common-mode impedance values of 45Ω, 90Ω, and 200Ω at 100MHz featuring a rated voltage of 5V and a withstanding voltage of 12.5V dc. The maximum dc resistance ranges from 2.5Ω to 4.75Ω.
