Capacitors Eaton Capacitors are a main component in electronic systems for storing and releasing electrical energy within a circuit. These two-terminal passive components feature two conductive plates separated by an insulating dielectric material. The application of voltage across the terminals creates an electric field, accumulating positive and negative charges on the plates. Eaton offers a diverse selection of capacitor technologies, encompassing supercapacitors and film capacitors. The film capacitors are known for their stability and minimal tolerance. They are tailored for use in electric vehicles (EVs), charging stations, renewable energy, motor drives, uninterruptible power supplies (UPS), and consumer applications. Supercapacitors are ideal for scenarios that require swift charge / discharge cycles and elevated power density. Their applications include vehicles, smart meters, and backup power sources across a variety of devices.
