UPS2D221MRD6

Aluminum electrolytic capacitors are an integral part of many electronic circuits. They are capable of delivering high capacitance values in a relatively small package, making them ideal components for applications where space is at a premium. One such capacitor is the UPS2D221MRD6, a cylindrical electrolytic capacitor with a wide range of uses and applications in a variety of circuits.

The main attribute that sets the UPS2D221MRD6 apart from other aluminum electrolytic capacitors is its size. Despite its small form factor, it is capable of delivering a remarkable 50V of DC voltage with an equivalent series resistance of 4.5Ω. This combination of size and performance makes the UPS2D221MRD6 ideal for many purposes, including high-frequency signal filtering, filter-path bypassing, timing, and additional energy storage.

The basic principle of operation of the UPS2D221MRD6 can be understood by examining its constituent parts. The central core of the capacitor consists of a wound coil of anodised aluminum which is then sealed in a protective casing. This winding, known as the capacitor\'s winding element, is connected to two external terminals and acts as the storage medium for stricly electrical energy. When a voltage is applied to the terminals, the winding stores charges of opposite sign, which are held in place by the magnetic field surrounding the anodised aluminum layer. This is how the UPS2D221MRD6 stores energy, and how it is eventually returned to the circuit when the voltage is reduced or removed.

In addition to its small size and high capacitance value, the UPS2D221MRD6 also features the added bonus of an extremely low leakage current. This is in part due to the fact that the anodised aluminum layer acts as an insulating barrier between the terminals, reducing the chances of electrical losses. Additionally, the outer casing of the capacitor is filled with a non-volatile oil, further reducing the risk of electrical shorting or arcing due to atmospheric dust or other contaminants.

In summary, the UPS2D221MRD6 is an ideal solution for a variety of applications where space is a limiting factor. Its size, voltage rating, capacitance value, and low leakage current make it suitable for a wide range of uses, including signal filtering, bypassing, and energy storage. With these features in mind, the UPS2D221MRD6 capacitor is an invaluable component to any electronic circuit.
