Capacitor singing
WebIf the possibility of high DC voltage being that close to head bothers or worries you, then the coupling capacitors are a good workaround. Bear in mind, if a capacitor is going to sing, it is going to do so in this position, due to the several hundred-volt swings. (Singing capacitors are like mini electrostatic loudspeakers. WebThese capacitors would solve the singing capacitor phenomenon from the root cause. For the vibration transfer from MLCC to the solder joint, many alternatives are available. The component suppliers offer low acoustic noise capacitors, such as metal terminals or metal plate capacitors, interposer or alumina substrate MLCCs, thicker dielectric ...
