Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an important component for various electrical applications. They are used in various electrical, electronic, medical, industrial, and automotive systems for their excellent performance and long life. UHV1A122MPD1TD aluminum electrolytic capacitors are a type of popular and reliable components. The UHV1A122MPD1TD is a low-voltage, surface-mounting type aluminum electrolytic capacitor with the capacitance value of 1.2µF, rated voltage of 16V and high ripple current which makes it suitable for high power applications.

Application Field

The UHV1A122MPD1TD aluminum electrolytic capacitor is suitable for high power applications such as various circuits of consumer products, medical instruments, computers, audio systems, power supply, etc. It is also an ideal choice for motor starting applications and can be used as a variable capacitor. With its high ripple current, it provides excellent compensation performance in audio frequency applications such as CD players.

Working Principle

The working principle of the UHV1A122MPD1TD is based on electrolytic double-layer capacitors. This type of capacitors is composed of an anode made of aluminum foil and a separator which is usually composed of two layers of paper. The electrolyte is an aqueous solution of organic acids or inorganic acids and serves as an electrolyte. The anode is covered with an electrolytic layer which is made up of ions at the molecular level. This molecular layer affects the electrical properties of the capacitor.

When voltage is applied to the capacitor terminals, the electrolyte will be ionized and form a double layer of charged particles. The electrons will go to the anode and the positive ions will go to the separator. This process will form a static electric field inside the capacitor which will store energy. The capacitance of the aluminum electrolytic capacitor is determined by the amount of ions that can accumulate and by the surface area of the aluminum foil. The capacitance also can be adjusted by varying the surface area of the aluminum foil and the thickness of the electrolytic layer.

The UHV1A122MPD1TD aluminum electrolytic capacitor has superior low impedance, excellent temperature characteristics, and long life due to its superior insulating performance. Its capacitance value of 1.2µF and a rated voltage of 16V provide excellent performance for various power applications including motor starting and frequency compensation.
