Document 565 -1 Power Filter Inductor For Zetex ZXCD1000 500 W Class D Solution This toroidal choke was developed for Zetex Semiconductors ZXCD1000 High Fidelity Class D Amplifier Solution. This application provides 500 Wrms into 4 Ohms. The ED0006-AL is the low pass filter for the high frequency switching PWM signal, enabling recovery of the lower frequency audio signal.
