Innovation Highlights In the motor controller, the DC power from the battery pack is used as the input power source, which needs to be connected to the motor controller through the DC busbar, the way is called DC-LINK or DC support, in which the capacitor we call busbar capacitor or support capacitor or DC-Link capacitor. Eagle Peak DC-link capacitors use organic film as the insulating medium, the metal layer evaporated on the surface of the organic film as the electrode, and the two films are wound into a capacitor, which has the advantages of stable capacity, small stray inductance, etc. It is suitable for the application of harsh conditions of use, and also for the application of motor controller. They are suitable for various applications with harsh usage conditions, low stray inductance and long service life.
