NOVELTY - The power electronic capacitor module (100) has a single pair of bus bars (110) having an external electrode support structure (111). An insulating support frame (120) is formed to expose external electrode support structure and wrap around a single pair of bus bars and thus support bus bars. A capacitor element (130) has a single pair of external electrodes (131) and inserted between a single pair of bus bars to be supported by the bus bars or the external electrode support structures and electrically connects the external electrodes to the external electrode support structures.    USE - Power electronic capacitor module for vehicle such as hybrid and battery vehicle.    ADVANTAGE - The power electronic capacitor module for vehicle reduces the number of solderings for connecting a bus bar and a capacitor, thus enhancing an equivalent serial resistance (ESR) property and removes high frequency ripple current occurring due to an increase in ESR, thus enhancing a heat-resisting property. The molding structure prevents the power electronic capacitor module from being contaminated due to an external humidity or foreign substance, or is formed on the capacitor element to be further firmly connected to the external electrode support structure, thus sealing the capacitor element. A power electronic capacitor module for vehicle reduces the number of solderings by inserting and thus mounting a capacitor between a single pair of bars and thus simplifies an assembly process. The power electronic capacitor module prevents degradation in capacity of the power electronic capacitor module, thus enhancing the reliability of a product, when a soldering portion is damaged due to an impact.
