Aluminum Electrolytic Capacitors

  An aluminum electrolytic capacitor, also known as an Alcap, is an electronic component used to store energy in circuits. It generally consists of two metal plates (aluminum foil or any other electrical conducting material) separated by an electrolyte. The aluminum foil or other conducting material acts as the anode and the electrolyte acts as the cathode. The voltage and current across the capacitor is determined by the electrolyte and the capacitance of the aluminum electrolyte.

  The UPW0J222MHD is an aluminum electrolytic capacitor and is primarily used in voice and data communications applications. It is a polarized capacitor with a working voltage of 16.5V. The capacitor is designed with a 22µF (microfarad) rating and offers a wide operating temperature range of -55°C to +85°C. It is designed with a radial leaded tin-plated finish.

Working Principle

  The working principle of the UPW0J222MHD aluminum electrolytic capacitor is based on the current flow through the anode to the cathode. When a voltage is applied across the two metal plates, an electric current will flow between them. This electric current will cause electrons to migrate between the two plates, creating a charge balance and capacitance across the plates. The capacitance is proportional to the area of the plates and the distance between them. When the electric current stops flowing, the charge remains on the plates until the capacitor is recharged.

  The UPW0J222MHD capacitor is designed to provide a low-impedance charge storage device for voice and data communications applications. The resulting charging and discharging of the capacitor helps to reduce noise, improve signal integrity and provide additional protection against voltage spikes and transients. It is also used for power supply decoupling in telecommunications and DC-DC power conversion.

Applications

  The UPW0J222MHD aluminum electrolytic capacitor is used in many applications such as cell phones, automotive electronics, power supplies, medical electronics and LED displays. It can also be used in power amplifiers, power meters, switch mode power supplies and flyback transformers. Its wide range of operating temperatures and low self-discharge rates make it an ideal choice for applications that require a long-term charge storage device.

  The UPW0J222MHD aluminum electrolytic capacitor is also highly reliable and has a long life expectancy. It can handle high inrush currents without much effect on its lifespan and has excellent surge and transient voltage characteristics. Its small size and low ESR also make it ideal for high-density circuit designs.
