Aluminum electrolytic capacitors, also known as electrolytic capacitors, are the most commonly used capacitors in various electronic products, and their size is very small.

B43851A2225M is a long-life aluminum electrolytic capacitor with self-healing properties. It significantly extends the life of components and improves their reliability. B43851A2225M is mainly used in power electronics, audio, lighting, communication, industrial control, automotive electronics, and other fields.

Working Principle: In the circuit, the liquid contained in the aluminum electrolyte capacitor is an electrolyte (aqueous solution of a weak acid, for example ethylene glycol) and has an AC voltage applied across its terminals. When there is an AC voltage applied, cations in the electrolyte travel to the anode and systemically deposit on the anode plate. These ions are attracted to the junction between the dielectric (fiberglass) and the anode plate. As the ions bridge the junction, the anode is formed as the capacitance increases.

The electrolyte contained in the capacitor contains an oxidant such as potassium hydroxide, which react with the ionic materials that have accumulated on the anode plate. Once the oxidant reacts with the ionic material, the conductivity of the plate is increased. This increased conductivity allows the capacitor to function again as before with no permanent loss of capacitance.

Polypropylene film capacitors are often used in place of aluminum electrolytic capacitors because they provide higher operating frequency and lower dielectric loss. However, aluminum electrolytic capacitors are still the favored choice in many applications because they offer much larger capacitance and voltage ratings than polypropylene film capacitors. As a result, they are more suitable for applications that require higher capacitance.

In fact, aluminum electrolytics are the most commonly used capacitors in many electronic products. They are very useful in filter networks and power supply regulation for their high capacitance and long service life. They also provide excellent energy storage capabilities in both pulse and continuous current environments.

As a result of their self-healing properties, B43851A2225M aluminum electrolytic capacitors are ideal for applications where capacitance must remain constant and reliable over long periods of time. As such, these capacitors are often used in audio systems, medical device power supplies, automotive electronics, and industrial control applications.
