Abstract
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 (PCBs). 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.
