Abstract
A decoupling capacitor is presented which is particularly useful in conjunction with either pin grid array type IC packages or with plastic leaded chip carrier IC packages. In accordance with the present invention, the multiplicity of elongated conductors of prior art decoupling capacitors are replaced with flat, wide conductive strips termed herein as skirts. These skirts extend outwardly from the top and bottom conductors of the decoupling capacitor and include small leads extendng therefrom which are solely for the purpose of either insertion into the circuit board or for connection with a surface pad on the circuit board. Thus, rather than the multiplicity of elongated leads found in the prior art, the present invention utilizes flat strips or skirts having very small leads extending therefrom. This skirt construction provides far lower inductance relative to the elongated leads of the prior art.
