relatively low noise capacitors are provided for surface mounted applications . electro - mechanical vibrations generate audible noise , which are otherwise relatively reduced through modifications to mlcc device structures , and / or their mounting interfaces on substrates such as printed circuit boards . different embodiments variously make use of flexible termination compliance so that surface mounting has reduced amplitude vibrations transmitted to the pcb . in other instances , side terminal and transposer embodiments effectively reduce the size of the mounting pads relative to the case of the capacitor , or a molded enclosure provides standoff , termination compliance and clamping of vibrations .
