EXC Common Mode Chokes

Panasonic EXC Common Mode Chokes are common mode noise filters. These chokes also include an (electrostatic discharge) ESD suppressor circuit. The EXC chokes are ideal for use in smartphones and table PCs. These chokes are ideal for ESD and noise suppression of high-speed differential data lines, such as MIPI and USB. The EXC chokes feature impedance ranging from 12Ω to 1kΩ. These chokes also provide 50mA to 500mA maximum DC current and 300mΩ to 5Ω maximum DC resistance. These common mode chokes operate over a -40°C to 85°C temperature range.
