Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor used in electrical and electronic systems. Compared to ceramic capacitors, they offer much greater capacitance, with values reaching into the thousands of farads. A key feature of aluminum electrolytic capacitors is their use of aluminum anodes, which gives them their high capacitance. For this reason, aluminum electrolytic capacitors are widely used in a range of applications, from computer motherboards and audio systems to instrumentation and power supplies.

UHV0J122MPD6 Application Field and Working Principle

The UHV0J122MPD6 is an aluminum electrolytic capacitor manufactured by Vishay. With a rated voltage of 25V and a capacitance of 220µF, the UHV0J122MPD6 is an ideal choice for low voltage applications, such as audio systems and power supplies. This capacitor is designed for surface mount applications and offers a wide temperature range, with an operating temperature of -55°C to +105°C. The UHV0J122MPD6 also offers a lower effective series resistance (ESR) compared to organic polymer capacitors, ensuring efficient load current delivery.

The working principle of the UHV0J122MPD6 aluminum electrolytic capacitor is based on the conversion of electrical energy into stored energy. When electrical current passes through the capacitor, the anode is charged and the cathode is discharged. An internal electric field is then created by the unequal charge between the two plates. This electric field serves as discharge capacitor, resulting in an increase in capacitance and stored energy.

At the same time, a dielectric is formed between the plates, resulting in improved insulation and protection against circuit failure or short circuits. The dielectric also eliminates electric arcing, thereby improving the stability and reliability of the capacitor. During electric surges, the electric field is increased even further, providing additional energy storage and protection.

The UHV0J122MPD6 aluminum electrolytic capacitor is highly reliable and offers longterm stability. It also offers great design flexibility, as it can be used in a range of different applications. It is ideal for medical and MIL applications, thanks to its high temperature range and low ESR. In addition, it is extremely resistant to harsh temperatures, making it suitable for use in automotive applications.
