Aluminum electrolytic capacitors use a thin oxide layer produced by applying electrical potential to an aluminum anode as the dielectric layer. This oxide layer can be very thin, yet grow so densely it increases capacitance and prevents leakage current. These capacitors can have a capacitance range of 0.01-2.2uF with ratings up to 500 VDC and are commonly used in consumer electronics, power supplies, and renewable energy markets. EET-HC2S221HA is a type of aluminum electrolytic capacitor that offers larger capacitance values, higher ripple current ratings, and low temperature coefficient values.

The EET-HC2S221HA aluminum electrolytic capacitors are rated for 105C, with a capacitance range of 2200mF and a voltage range of 25VDC. These capacitors feature a low equivalent series resistance (ESR) allowing for high ripple current and low noise performance. They also have low temperature coefficient which allows them to provide stable and reliable performance even in harsh environmental conditions. The capacitors also feature a robust construction with a metal case, sealing base and rubber seals. The sealed base construction helps reduce the effects of temperature, humidity and other environmental influences.

The EET-HC2S221HA aluminum electrolytic capacitors have wide applications in switching power supplies and power ration systems, as well as in industrial, automotive and consumer electronics. In switching power supplies, this type of capacitor can be used to effectively filter high frequency ripple current and electrical noise. In power ration systems, their high current handling capabilities make them suitable for both filtering and dc-link cyclic applications. In the automotive field, they have widespread use in starter motors, engine control systems and gear control systems, as well as in consumer electronics like audio amplifiers, smart home appliances and portable device power supplies.

The aluminum electrolytic capacitors work on the principle of using an oxide layer to store charges. This oxide layer is formed when an anode is exposed to a voltage. The oxide layer is very thin, but its capacitance increases significantly when charges are stored. The charge can then be released when a larger voltage is applied to the capacitor, allowing the current to flow through it. This type of capacitor does not require external support in order to maintain its shape, making it suitable for many applications. Aluminum electrolytic capacitors also have the ability to withstand very high voltages, making them ideal for high voltage applications.
