ABSTRACT:
A decoupling capacitor and method of manufacture thereof are presented wherein the decoupling capacitor is formed from a lead frame which contains the four leads of the capacitor (two of which are electrically inactive) on a single plane. The use of a lead frame automatically provides the dimensional tolerances necessary for encapsulation molding of the decoupling capacitor. The decoupling capacitor is a hermetically sealed capacitive unit consisting of a multilayer monolithic ceramic capacitor (for higher capacitance values in combination with other desirable properties such as flat capacitance vs. temperature characteristics), active leads bonded to the capacitor and dummy pins for auto-insertion into printed circuit boards.
