UEP1E222MHD

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are the most commonly used type of electrolytic capacitor, and are available in a wide range of sizes and capacitances. AECs are made up of two electrodes, one positive and one negative, separated by an electrolyte, typically aqueous solution. They are passive components used in many electronic circuits, such as power supplies, amplifiers, and audio preamps. The capacitance of AECs is usually expressed in farads (F).

UEP1E222MHD Application Field and Working Principle

The UEP1E222MHD is an aluminum electrolytic capacitor created by the Japanese company Nichicon. It is a long life radial type product, designed for use in electronic circuits such as automotive applications, power supplies, and SMPS. It has a rated capacitance of 220µF and has a rated voltage of 6.3V. The capacitor is made of two aluminum electrodes separated by a polarized electrolyte solution. The aluminum electrodes have a high electric potential difference between them, creating a potential difference that can be used to store electrical energy.

The working principle of an Aluminum electrolytic capacitor is quite simple. When a voltage is applied across the two electrodes, the current that flows will react with the aluminum, causing it to release free electrons. These electrons then accumulate on one of the electrodes, causing it to become positively charged. On the other electrode, electrons are removed, causing its charge level to become negative. As a result there is a potential difference created between the two electrodes, which is where the charge stored in the capacitor comes from.

The UEP1E222MHD is capable of withstanding loss of voltage and ripple current, and as such is suited for use in high frequency SMPS circuits. It has an operating temperature range of -40°C to +105°C, and its life expectancy is up to 8,000 hours at +105°C. Its lead-free solderability ensures environmental compatibility and helps to minimize the risk of lead contamination. The UEP1E222MHD has a miniature size and is ideal for use in crowded PCBs.
