Aluminum electrolytic capacitors are a type of capacitor that utilizes the characteristics of aluminum oxide film. The technology is also referred to as electrolytic capacitors because of the use of an electrolyte. Electrolytic capacitors are composed of an anode of aluminum (or sometimes tantalum) foil and a cathode of metal oxide. An electrolyte of solvent and ions is placed between the aluminum and metal oxide to form an electrically conductive layer. This conductive layer serves as the dielectric material between the two conductors.

The UFW1E221MPD is one of the most popular aluminum electrolytic capacitors available. It is a two-section, two-pin capacitor with a lead pitch of 5 mm and a capacitance of 2.2 µF (microfarads). The UFW1E221MPD has a voltage rating of 16 VDC and is rated for temperatures up to 85°C. The UFW1E221MPD is typically used in consumer electronics, audio amplifiers, and power supplies.

The working principle of the UFW1E221MPD is based on the principles of electrostatics. When a voltage is applied to the capacitor, it creates an electrostatic field between the anode and the cathode. This electrostatic field causes charges to be collected on the aluminum anode and metal oxide cathode. This creates an electric field between the two conductors, which allows the capacitor to store an electric charge.

The UFW1E221MPD utilizes a unique design that allows it to have higher capacitance ratings than other capacitors with the same size and voltage ratings. This is due to its use of an alloyed aluminum anode that allows the capacitor to withstand higher temperatures without the risk of damaging the capacitor. Additionally, the capacitor has a wide operating temperature range (-40°C to +85°C) and a long shelf life (5 years).

The UFW1E221MPD is a reliable and cost-effective capacitor suitable for a wide range of applications. It is particularly well suited for use in DC power supply circuits, audio amplifiers, and consumer electronics. Its pitched leads and small size make it easy to mount and it is rated for up to 16 VDC. Its ability to withstand high temperatures and its long shelf life make it one of the most popular aluminum electrolytic capacitors available.
