The average consumption current (mA), is described in the form of MAX.xx. This means that, if the rated voltage is applied without limiting electric current, the average current value will not surpass xx mA. Be careful, as it is not meant that electric current exceeding xx mA must not be applied to the product. In reality, maximum current 2 to 3 times higher than the average current is required as peak current. Therefore, a driving current that can supply sufficient current should be provided. If the peak current is restricted, there can be a case in which sound pressure will not be output as specified.
(Example) In the case of FZ111A, whose average current is MAX. 10mA, prepare a driving circuit that can supply the peak current of at least 30mA.
