Common mode choke for automotive grade SMD module

Murata DLW21SH common-mode choke is an automotive grade SMD module of single-circuit, winding type construction with 0805/2012 housing size (2mm x 1.2mm). These noise suppression devices have current ratings of 280mA or 300mA, voltage ratings of 20VDC, and common-mode impedance of 67Ω to 390Ω ±25% at 100MHz.

The series operates from -40°C to +125°C with derating exceeding +105°C. Murata DLW21SH common-mode choks are suitable for automotive applications such as drivetrains/safety devices, infotainment/comfort devices, USB, HDMI, and low-voltage differential signal (LVDS), the latter being an interface for LCD panels. The DLW21SH391XQ2L choke is also suitable for on-board cameras and other high speed interface (SerDes) coaxial power supply (PoC).
