CONDUCTIVE ADHESIVE ATTACHMENT OF CAPACITOR TERMINALS

摘要

An improved electrical terminal attachment process for a wound polymer film/foil or metallized film capacitor is described that minimizes thermal damage to the capacitor structure and improves the current carrying capability of the capacitor. The process employs an electrically conductive adhesive that can be cured at low temperatures. The disclosed process improves the reliability of the capacitor when used at high RMS or pulsed currents. It also enables capacitor application structures with reduced equivalent series inductance that would be otherwise difficult or impossible to fabricate.
