Aluminum electrolytic capacitors are a kind of super capacitor with aluminum oxide film as the dielectric, and aluminum foil as the electrode. The UPM1H821MHD is an aluminum electrolytic capacitor distinguished by its low ESR and maximum temperature resistance.

The UPM1H821MHD is designed for a wide range of applications, including communication equipment, power control systems, servers, computer motherboards, and automotive electronics. It can also be used in power supply, LED lighting, inverter motor control, and other fields.

The UPM1H821MHD is a non-polar aluminum electrolytic capacitor with a voltage rating of 35V. Its working temperature range is from -40 to 125°C. This type of capacitor is known for its high capacitance and low dissipation factor.

The UPM1H821MHD features a series of robust terminals with a 9.5 mm snap-in type spacing. The terminals are 8.0 mm in length and have M2 mounting holes. It also features a friction grip system that makes it easier to screw in and out.

The UPM1H821MHD is a radial aluminum electrolytic capacitor with a capacitance of 820 μF and a capacitance toleration of ±20%. It has an operating life of 2000 hours at its rated voltage and an ambient temperature of 85°C.

The UPM1H821MHD achieves its low equivalent series resistance (ESR) by employing advanced design and materials. The design consists of two electrodes and two resistor-type elements that dissipate stored energy. The materials used to construct this aluminum electrolytic capacitor are also special in that they have a high temperature coefficient of resistance, high self-healing characteristics, and excellent temperature and corrosion resistance.

The working principle of the UPM1H821MHD is simple. When voltage is applied, the current flowing through the terminals of the capacitor is limited to a safe amount. This is done by the resistor-type elements, which act as a current limiter. With voltage applied, the capacitor stores a charge in its dielectric material. The stored charge forms an electric field between the two electrodes, creating an inhibitory voltage. This voltage maintains a steady-state charge and current flow through the capacitor\'s terminals.

The UPM1H821MHD is an excellent aluminum electrolytic capacitor that provides a reliable, efficient, and cost-effective solution for a variety of applications. Its design and materials make it ideal for high temperature applications, while its low ESR makes it well-suited for modern electronic circuits.
