UPJ2A220MPD1TD Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most commonly used type of capacitors and consist of a dry film layer assembled between two aluminum plates. The layers are held in place by a dielectric oxide layer, typically oxide-nitride-oxide. The oxide layer acts as a barrier to the passage of current and can usually withstand a large amount of electrical energy. The aluminum plates are connected to the opposing ends of an anode, which can be either positive or negative. The anode is typically a flat aluminum foil.

The UPJ2A220MPD1TD is an aluminum electrolytic capacitor with the voltage rating of 220W and a temperature range of -40°C to 85°C. This device is intended for use in automotive, industrial, lighting, and other applications. It is capable of providing reliable performance in harsh environments.

Application Field

The UPJ2A220MPD1TD can be used in a wide range of automotive and industrial applications. Its features make it ideal for use in demanding conditions, such as extreme temperatures and high-shock environments. It is particularly useful when managing transient current or power in switching power supply systems.

This capacitor is suitable for lightweight electronic control systems, including automotive brakes and navigation systems. It can also be used in sensors and communication equipment such as cellular phones, computers and RF modules. Additionally, it is an excellent choice for use in motor drives and high-voltage AC circuits.

Working Principle

The UPJ2A220MPD1TD operates on the principle of electron accumulation and depletion. Electrons accumulate at the anode surface due to their negative charge and are depleted at the opposite surface due to the high electric field strength near the anode. This creates a static electric field between the two surfaces that stores energy. When a potential difference is applied across the two surfaces, a current flows, potentially charging and discharging the electric field.

When the external voltage is removed, the capacitor starts to discharge. This is due to the time-constant RC (resistance-capacitance) network, which controls the rate at which the capacitor can discharge its stored energy. The UPJ2A220MPD1TD has a very low leakage current, making it suitable for use in systems that require long-term energy storage such as energy-harvesting systems.
