Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components that store energy in the form of an electric field. They are one of the most widely used types of capacitors. The UUG1E471MNQ1ZD series is an aluminum electrolytic capacitor that is particularly suited for use in automotive, communications, and power supply applications.

Application Field

The UUG1E471MNQ1ZD series is designed to meet the needs of automotive, communications, and power supply applications. It features a capacitance range of 47 microfarads to 1,200 microfarads, a rated voltage of 10 to 22 volts, a leakage current of 130 milliamps to 160 milliamps, and a temperature range of - 25°C / + 85°C. This series of aluminum electrolytic capacitors can be used in various automotive applications, such as on/off control of headlights, doors, mirrors, and wipers; automotive air conditioning control; refrigerators; voltage regulator circuits; power supplies for LCDs, LEDs, and motor drivers; and low-power audio amplifiers.

Working Principle

Aluminum electrolytic capacitors take advantage of the electrolytic property of aluminum. An electrolyte is sandwiched between two slivers of aluminum foil — one for the positive terminal and one for the negative terminal. An electrolytic solution is then added, which saturates the space between the two plates. This solution contains positive ions that cause the porous aluminum foil to become polarized, creating the electrical field. The capacitance of the capacitor is determined by the area of the plates and the dielectric of the electrolyte solution, allowing it to store energy in the form of an electric field.

The UUG1E471MNQ1ZD series is a special type of aluminum electrolytic capacitor. It uses a highly efficient evaporated synthetic electrolyte, which improves the reliability and life of the capacitor. This series also has a cannulated terminal, which eliminates the need for soldered connections. The cannulated terminal helps to reduce the risk of high noise caused by vibration or mechanical shear. This series also features a high ripple current rating, low equivalent series resistance (ESR) value, and a high shelf life.

Aluminum electrolytic capacitors are an essential component in many electronic devices. The UUG1E471MNQ1ZD series is particularly suited for automotive, communications, and power supply applications. It offers high reliability and a long service life, making it a great choice for a number of applications.
