Aluminum electrolytic capacitors are widely used in power supplies, switching power supplies, motors, audio and other fields. The UPJ1V391MPD1TD aluminum electrolytic capacitor is no exception.

The UPJ1V391MPD1TD is a radial lead, 85°C-rated aluminum electrolytic capacitor. It has an operating temperature range of -40°C to +85°C and a long life of 3000 to 5000 hours. The capacitance ranges from 0.5µF to 10µF, the rated voltage is 16VDC, and the capacitance tolerance is ±20%. With those features, the UPJ1V391MPD1TD is utilized in a wide range of applications, such as motor control, power supplies, power filtering, switching power supplies and audio equipment.

The working principle of an aluminum electrolytic capacitor is similar to that of any other electrolytic capacitor. It consists of two metal plates, which are separated by a dielectric electrolyte. When a potential difference is applied across the two plates, electrons are drawn from one plate to the other. This causes a charge to build up on the plates, which creates an electric field. The electric field between the plates effectively increases the capacitance of the capacitor.

The aluminum electrolytic capacitor has a very high electrical conductivity due to the large surface area of the aluminum plates. This makes these types of capacitors ideal for applications where a high current is required, such as in motor control and switching power supplies. Additionally, the electrolyte has a very high dielectric constant, which increases the capacitance of the capacitor.

In summary, the UPJ1V391MPD1TD is a radial lead, 85°C-rated aluminum electrolytic capacitor that is widely used in motor control, power supplies, power filtering, switching power supplies and audio equipment. Its working principle is similar to that of any other electrolytic capacitor, and it utilizes the high electrical conductivity and dielectric constant of the aluminum plates and electrolyte to produce a high capacitance value.
