A system and method for RF immunity of an electret condenser microphone. In one embodiment, the microphone comprises a printed wire board, an amplifier, a capacitor. The amplifier and the capacitor are mounted on the printed wire board such that longitudinal axis, i.e., the axis defined by the line between the output pin and the ground pin, of the capacitor is perpendicular to the longitudinal axis of the amplifier. According to one embodiment of the method of the present invention, an electret condenser microphone according to the present invention is provided, and current is provided to the capacitor to result in the creation of a magnetic field about the longitudinal axis of the capacitor. The magnetic field created is positioned such that it does not significantly contribute to the generation of RF current in the amplifier.
