Aluminum Electrolytic Capacitors offer great many advantages over other capacitors. Long life, low ESR (Equivalent Series Resistance), high load current, high temperature endurance and low cost are just some of the benefits they can provide.

The EEE-1CA220NP is a radial leaded aluminum electrolytic capacitor with a soft termination (top hat) for easy insertion into a printed circuit board. It offers 8.0 mm diameter, -10 to 85 °C temperature range, 105 °C rated voltage, 10 mm lead length and off-board axial leads of tinned nickel plated steel. The series is designed with a high-quality electrolyte and rare-earth element materials to ensure the best performances even at the highest temperatures.

It is used in a wide range of applications, such as power supply and power modules, DC/AC inverters, programmed voltage controllers, solar inverters and automotive electronics. Furthermore, it can also be used in any other application requiring a low impedance, long-life and low losses.

The working principle for an aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. The capacitor has an anode and a cathode and an electrolyte. When a voltage is applied across the two terminals, electrons and ions travel across the electrolyte. Electrons travel from the anode and ions flow from the cathode. At the anode, electrons are combined with metal cations to form metal, reducing the capasitance. At the cathode, ions react with metal from the electrolyte to form metal cations, which increases the capacitance.

The metal that is deposited at both the anode and cathode will form an insulating layer between them, reducing the capacitance of the capacitor to a minimum. Since the metal cations at the anode will combine and form an insulating layer between them, the anode will be the actual layer that stores the energy.

The EEE-1CA220NP has an extended lifetime of up to 5,000 hours at 85°C and 85% relative humidity, making it ideal for high temperature and harsh environments. The nickel-plated steel leads are pre-tinned for superior strength, superior solderability and long-term reliability. The whole series offers a high ripple current, high reliability and low ESR, making it suitable for use in a variety of electronic devices.

To sum up, the EEE-1CA220NP is a radial leaded aluminum electrolytic capacitor with a soft termination for easy insertion and removal from modern printed circuit boards. It offers great long life, low ESR, high load current capacity, high temperature endurance and very low cost. Its use includes power supplies, power modules, DC/AC inverters, programmed voltage controllers and automotive electronics.
