Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are commonly found in electronic circuitry due to their high capacitance and long life. They are also known as aluminum electrolytic capacitors, electrolytic capacitors, and simply caps. These capacitors consist of two electrodes, an anode and cathode, and are filled with an electrolytic solution such as potassium hydroxide or sodium hydroxide.

The UKA1A221MED is a non-solid aluminum electrolytic capacitor with a SC terminal type. It is built in a 3-piece, closed-end construction and is fully rated for up to 85oC. The standard capacitance range for this capacitor is 0.1 uF – 5600 uF and has a voltage rating of 6.3V – 800V DC.

The UKA1A221MED is designed for use in applications where space is limited as well as for applications that require high capacitance values. It is a versatile device, as it is suitable for a wide range of electronic applications such as power supply circuits, filtering, decoupling, and resonance.

A primary benefit of using the UKA1A221MED is its high degree of performance and reliability. It has a long service life when used with rated voltage and temperature parameters, and can be used continuously in a wide range of temperature and humidity levels. It is also resistant to environmental factors such as dust, oil, and grease, and has good electrical features such as low loss, low equivalent series inductance, and low equivalent series resistance.

The working principle of the UKA1A221MED is based on the dielectric polarization of the electrolyte solution. When it is connected to a DC voltage source, an electric field is created, which causes the electrolyte solution to polarize and separate the electric charge on the anode and cathode. This creates a storage cell out of the electrolyte solution and forms an electric double layer. Thus an electric capacitance is formed between the anode and cathode.

The UKA1A221MED also has a self-healing mechanic quality. This is a beneficial feature as it helps maintain the capacitor’s performance over time. This feature works when electrical stresses, such as overvoltage, cause dielectric breakdown at certain points in the circuit. This type of breakdown occurs when the electric current breaks down the electrolyte molecules between the anode and cathode. However, the electric double layer reforms and the electrolyte molecules become re-polarized. Thus, this capacitor can work for many years without needing any maintenance or repairs.

In conclusion, the UKA1A221MED is an advanced type of aluminum electrolytic capacitor. It offers a wide range of advantages over other capacitors, such as its high capacitance, long life, and self-healing properties. Due to its excellent performance, it is widely used in a variety of applications and is a great choice for long-term, reliable operation.
