Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the oldest types of capacitors and, as their name suggests, are composed of aluminum and electrolyte. They are used to store electric charges in various circuits and, depending on their size, design and material used, can range from a few picofarads up to millions of farads.

The UVR1HR33MDA is a class of aluminum electrolytic capacitor with a unique design, designed to withstand adverse environmental conditions. It has a low ESR and is designed to work at rated temperatures up to -40°C. Its rated voltage is 25VDC.

This particular capacitor is also known for its low-profile design, which makes it ideal for use in space-constrained applications, ranging from telecom equipment to consumer applications. It is an excellent alternative to more expensive ceramic capacitors and film capacitors in applications that require lower radiation and less noise.

Application Field

The UVR1HR33MDA is commonly used in various types of electric circuits, from low-voltage radio circuits to high voltage power electronics. Its low cost and durability make it an ideal choice for use in commercial products and industrial machinery. It is often used in automotive, telecommunication, medical and consumer electronics applications.

Due to its low internal resistance and high capacitance, the UVR1HR33MDA offers superior performance compared to normal aluminum electrolytic capacitors. It is also suitable for high temperature applications, as its specially designed solution offers excellent thermal stability, allowing it to be used in extreme environmental temperature conditions.

Due to its high-purity, low ESR design, the UVR1HR33MDA is also often used in frequency converters, in which it can provide a clean, reliable power supply for sensitive electronic equipment.

Working Principle

Like other aluminum electrolytic capacitors, the UVR1HR33MDA works according to the principle of electrolysis which requires electricity to flow through two plates (an anode and a cathode) with an electrolyte medium in between them. As the current passes through, electrons are deposited on the anode, creating a charge imbalance between the two electrodes. This, in turn, creates an electrical field that can store electrical energy.

The anode and cathode of an aluminum electrolytic capacitor are made of aluminum foil and a layer of electrolyte. The capacitor is constructed with winding layers of both foils, interleaved with a separator paper impregnated with the electrolyte. When an electric field is applied, an electric charge is created on the capacitor, which can be used to store electrical energy.

Due to its unique design, the UVR1HR33MDA offers superior performance compared to other capacitors. It is able to store more electrical charge due to its low internal resistance and high capacitance, which makes it well suited for applications that require clean, reliable power supplies.

In addition to its superior performance, the UVR1HR33MDA is a robust capacitor that is durable and able to withstand extreme environmental temperatures. This makes it an ideal choice for a variety of applications ranging from commercial products and industrial machinery to medical and consumer electronics.
