UPW0J221MEH

Aluminum Electrolytic Capacitors are electronic components that store energy in an electrical field and are primarily used in circuits to provide a stable voltage supply. The UPW0J221MEH is one such capacitor from Panasonic Corporation, which is widely used in a variety of applications ranging from communications equipment to consumer appliances. This article will discuss the application field and working principle of this capacitor.

Application Field: The UPW0J221MEH capacitor is suitable for use in a wide array of applications. It is used in a variety of electronic circuits such as power supplies, switchmode power conversion, DC-DC converters, and clock circuits. Its high capacitance-voltage ratio makes it ideal for use in switching applications such as noise suppression and voltage clamping. Moreover, it is often used in circuits that require a high ripple current and low ESR such as in power supply filtering applications. Additionally, it is also suitable for high-frequency circuits, motor drives, audio circuits, and automotive systems.

Working Principle: Aluminum Electrolytic Capacitors utilize an electrolytic solution as its dielectric material. This is an excellent dielectric material as it allows for a large capacitance value for a small size. The capacitor works by utilizing the Faraday effect, which states that a voltage is created across the electrolyte when a magnetizing field is applied in the opposite direction to the flow of current through the electrolyte. When a voltage is applied to the capacitor, a current flows through the electrolyte, and the Faraday effect results in an opposing voltage that is created across the electrolyte. This opposing voltage is the same as the applied voltage, and therefore the capacitor stores energy.

The UPW0J221MEH capacitor has an extremely high capacitance value of 221 microfarads (μF). This makes it suitable for use with a wide range of voltage levels, withstanding up to 20 volts of DC voltage (or 10 volts of AC voltage). It supports an operating temperature range of -25°C to +85°C, and has an operating life of at least 2000 hours at room temperature. This makes it ideal for use in a variety of industrial and commercial applications that require long-term reliability.

In conclusion, the UPW0J221MEH from Panasonic Corporation is an excellent aluminum electrolytic capacitor for use for a variety of applications ranging from high frequency circuits to power supply filtering. Its high capacitance-voltage ratio, temperature range, and long operating life make it ideal for use in industrial and commercial applications. Now that you know a bit about the application field and working principle of aluminum electrolytic capacitors, you can make an informed decision about the best capacitor for your particular application.
