Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used capacitors. They are developed from the previous paper-wax capacitors. It is composed of aluminum foil, non-woven fabrics, electrolytes and sealed cans. Its main features are high capacitance and long service life.

UPW1A101MDH application field and working principle

UPW1A101MDH is a type of aluminum electrolytic capacitor developed and produced by NEC TOKIN, mainly used in DC circuit and signal coupling. It is made of an anodized aluminum oxide film and an electrolyte, with a rated voltage of 25V, an insulation resistance of 100MΩ, a capacitance of 1000 μF, and a temperature range of -25°C; ~ 85°C;. The capacitor has a large capacity and small volume, and is suitable for high frequency communication systems, electric vehicles, control equipment, DC link circuits and telecommunications.

The working principle of UPW1A101MDH aluminum electrolytic capacitor is to form and enlarge an electric field in the oxide film of the anode aluminum foil plate adjacent to the porcelain paper with different medium characteristics inside and outside the anode foil through a simple mechanism. Due to the large dielectric constant of the oxide-aluminum membrane and the low dielectric characteristic of the film, the capacitor can store and reduce the energy in current form in the whole work process.

Delicate oxidation technology can make the UPW1A101MDH aluminum electrolytic capacitor have higher insulation resistance, greater capacitance and lower equivalent series resistance. At the same time, the core of NEC TOKIN UPW1A101MDH is made of special alloy, which has excellent solderability and corrosion resistance, and the capacitor also uses high temperature resistant and viscous organic electrolyte, so it can ensure its stable performance and long-term reliable performance.

Overall, the UPW1A101MDH aluminum electrolytic capacitor is a reliable and stable electronic component. Its small size and high capacity make it very suitable for high frequency communication systems, electric vehicles, control equipment, DC link circuits and telecommunications.
