Aluminum electrolytic capacitors are well-known components commonly used in power supplies, telecommunications, electronics, and automotive applications. The UHM1A102MPD9 is one of the more popular aluminum electrolytic capacitors available on the market today.

This capacitor is from the world leader in capacitor technology, Cornell Dubilier, and is constructed with a dry tantalum material. This combination helps give it a high temperature, long life, and an extended frequency range of operation that make it suitable for many different uses.

The UHM1A102MPD9 has a number of key features that make it an ideal choice for power supply, telecommunication, electronic, and automotive applications. Features like a wide operating temperature range, moist proofing, short-term ripple resistance, low inductance, reliable long-life, small size, good capacitance-frequency characteristics, and the ability to withstand surge current are all found in this type of capacitor.

The UHM1A102MPD9 application field consists of the -55 to +155 Celsius temperature range, and is designed to operate at 1 Vrms with a 4–20 Hz test frequency. This capacitor is ideal for use in DC-DC converters, switching power supplies, and other electronic circuits with low, static capacitance values. It\'s also widely used in automotive applications as a power factor controller capacitor.

The working principle of an aluminum electrolytic capacitor is based on the Faraday induced current law which states that a potential difference is created when a non-conductive material is placed between two conductive plates. When a magnetic field is applied to, or created in, the space between the two conductive plates, a current is generated in the material.

The UHM1A102MPD9 utilizes this principle with the tantalum insert material to form the capacitor element. A non-conductive paper or plastic is used between the two plates, acting as the dielectric which produces the capacitive effect. The amount of capacitance generated is determined by the type of dielectric and how it is formed. By varying the shape, size, thickness, and the type of rolled aluminium used, the amounts of capacitance produced can be varied and tailored to specific application needs.

The UHM1A102MPD9 is a dry-tantalum electrolytic capacitor that can stand up to high temperatures and has a long service life of up to 2000 hours. Not only that, but this particular capacitor also has a wide frequency range and low inductance, making it ideal for use in power supplies and telecommunication devices as well as automotive applications. Its wide operating temperature range and moist proofing makes it resistant to sudden environmental conditions; making it a reliable option for a variety of applications.
