电视遥控器中用的是MOS集成电路,耗电极微.不按键时电流仅几微安,有的不足1微安,按键时电流为几毫安至十几毫安(随机型而异)不等,所以电池使用时间一般达一年以上.所谓耗电快是指遥控器各项功能正常但新电池使用寿命不足三个月.通常有以下几个原因.
TV remote control is used MOS integrated circuits, micro-power consumption.When the button is not only a few micro-current, some less than 1 microampere, when the key current of a few milliamperes to a dozen milliamperes (random varies) Range, so the battery life of more than a year generally so-called power fast refers to the remote control function is normal but the new battery life less than three months usually there are several reasons.
