Murata DLW21SH常規式扼流圈
Murata DLW21SH Common Mode Chokes are automotive-grade SMD modules with a single circuit, winding type structure, and 0805/2012 case size (2mm x 1.2mm). These noise suppression devices offer 280mA or 300mA rated current, 20VDC rated voltage, and 67Ω to 390Ω ±25% common mode impedance (at 100MHz). The series operates in a -40°C to +125°C temperature range with derating over +105°C. Murata DLW21SH Common Mode Chokes are suitable for automotive applications such as powertrain/safety equipment, infotainment/comfort equipment, USB, HDMI, and low voltage differential signaling (LVDS), which is an interface used for LCD panels. The DLW21SH391XQ2L choke is also suitable for power over coax (PoC) for onboard cameras and other high-speed interfaces (SerDes).特點
