1. A capacitor module for use with a power transistor comprising:
- a housing having at least two holes completely therethrough;
at least two wound capacitors enclosed within the housing; and
first and second mounting inserts at least partially lining the holes, the capacitors being connected in parallel, by way of connections internal to the housing, to the first and second mounting inserts, wherein the first and second mounting inserts are adapted for connection to the power transistor.

Abstract
A capacitor module for use with an IGBT including an epoxy housing having two holes completely therethrough. Within the housing are two wound capacitors which are connected in parallel. Additionally, there are two mounting inserts which at least partially line the holes of the housing. The wound capacitors are also connected to the first and second mounting inserts which serve as the terminals for the capacitor module. As a result, the capacitor module exhibits very low self-inductance as well as very low ESR.

11. A capacitor module for use with an insulated-gate bipolar transistor (IGBT) comprising:
-
a housing having at least two holes completely therethrough; first and second mounting inserts at least partially lining said holes, the mounting inserts sufficiently spaced, and extending beyond a face of the housing, to provide terminals for connection to the IGBT; and at least two wound capacitors enclosed within the housing, each capacitor positioned completely on one side of a plane intersecting the first and second mounting inserts, the capacitors being connected in parallel by leads connected to the first and second mounting inserts.
