CSM Series: Margin Capacitors

csm photoMargin caps have the topside electrode withdrawn from the edges in order to increase the distance between electrodes and dramatically decrease the possibilities of shorting when epoxy die-mounting. This style is also widely used for optical recognition-based assembly. Increased margin sizes and special terminations are available for high power LC filter applications.

  • MARGIN CAPACITORS CAN BE CUSTOMIZED TO ANY SIZED SQUARE OR RECTANGLE
