Aluminum electrolytic capacitors, also known as aluminium electrolytic or anodized electrolytic capacitors, are polarized capacitors consisting of two aluminum foils with an oxide layer acting as the dielectric material between them. The anode is made of aluminum foil that has been oxidized and an electrolyte containing ions of the same polarity as the oxide layer. The UFW1E222MHD1TO is an aluminum electrolytic capacitor with a straight radial lead. It has a voltage rating of 350V and capacitance of 2.2µF.

The UFW1E222MHD1TO is designed for applications in avionics and industrial electronics, where reliability is key. These capacitors are known for their high capacity, low cost, low equivalent series resistance (ESR), and fast charge/discharge times. They have a strong tolerance for high temperatures, and as such are suitable for use in a wide range of operating conditions. This makes them ideal for use in power factor correction (PFC) circuits, dynamic braking and power management systems, electric vehicles, and power circuits.

The UFW1E222MHD1TO has a lifetime of 3000h at 105℃. It has a rated ripple current at +105℃ of 0.38A with a frequency range of 100 to 120Hz. It features a small physical size and low ESR, making it ideal for applications that require minimal physical space. Its high ripple current allows it to handle very high inrush currents with minimal damage. The capacitor’s high capacitance density makes it ideal for high current applications such as switching power supplies, high frequency filtering, and resonance.

The UFW1E222MHD1TO works on the principle of the electrochemical formation of the oxide layer between the two aluminum foils. It is this oxide layer that acts as a dielectric material and allows electric charge to be stored and discharged when an external voltage is applied. When a voltage is applied across the capacitor, current flows through the electrolyte and ions are attracted to the oxidized aluminum ions, forming a layer of conductive oxide. This process forces the two aluminum foils to be polarized, and the capacitor is formed.

When the voltage is removed, the flow of electrons reverses, and the reverse current removes the oxide ions, restoring the capacitor to its original state. This process can be repeated many times, allowing a capacitor to be charged and discharged multiple times without loss of performance. Because of its simple construction, the UFW1E222MHD1TO is highly reliable and can be used for many years without any performance degradation.

The UFW1E222MHD1TO is optimized for applications such as power supplies and high frequency circuits. Its low ESR and high ripple current capacity make it ideal for these applications. It is also suitable for use in avionics and industrial electronics due to its low cost and high tolerance to temperature changes. As such, the UFW1E222MHD1TO is an excellent choice in a wide range of applications.
