Aluminim Electrolytic Capacitors

The UHE0J152MPT Aluminum Electrolytic Capacitor is a general-purpose volumetric capacitor manufactured by the Japanese electronics conglomerate NEC. The capacitor is an electrolytic, polarised type, and is used in a wide range of electronic application fields. This article will discuss the UHE0J152MPT\'s application field, working principles, and operating characteristics.

Application Field

The UHE0J152MPT is a long-life electrolytic capacitor, commonly used for power supplies, signal processing, microprocessors, and other high-frequency electronic circuits. The UHE0J152MPT is also a popular choice for automotive and medical electronics, due to its high reliability and long-term operating life. The UHE0J152MPT also has a wide range of temperature operating range between -25C to +85C.

Working Principle

The UHE0J152MPT has a volumetric design, which utilizes a two-layer construction of Aluminum and an electrolytic solution to provide electrical capacitance. The capacitor is a “polarized” or “polarized” type, which requires correct polarity when connecting. When connecting the capacitor, anode should be connected with plus and cathode should be connected with minus, to prevent damage to the capacitor.

In operations, a voltage is applied across the two terminals of the capacitor, which generates an electric field in the electrolytic solution. When the electric field is sufficient enough, electrons begin to move from anode towards cathode, which creates an electrostatic charge.

The Aluminum layer is etched with a chemically treated pattern, which creates an array of small-diameter holes. These holes are covered with electrolytic solution, which also creates an electrostatic charge. As electrons move from anode to cathode, the electrostatic charge begins to store energy in the form of a electric field.

The stored energy acts as a electrical capacitor, which can be used as a power source for microprocessors, signal processors, and other electronic circuits. The UHEOJ152MPT is also equipped with a safety discharge resistor, which ensures the stored energy is safely discharged in the event of a overload.

Operating Characteristics

The UHE0J152MPT has a wide operating temperature range of -25C to +85C, and a capacitance range of 0.1 - 4700µF. The capacitance of the UHE0J152MPT can be measured by applying a voltage to the capacitor, and measuring the electrical current through the electrolytic solution.

The UHE0J152MPT also has a temperature coefficient of -0.05% per degree Celsius, which is relatively low when compared with other capacitors. This low temperature coefficient ensures the capacitor maintains its capacitance when exposed to extreme temperatures.

The UHE0J152MPT is also equipped with burst protection, which limits the amount of current that can pass through the capacitor in case of a short-circuit. The burst protection also ensures that the capacitor is protected from damage due to overvoltage.

In conclusion, the UHE0J152MPT Aluminum Electrolytic Capacitor is a general-purpose volumetric capacitor manufactured by the Japanese electronics conglomerate NEC. The capacitor is an electrolytic, polarised type, and is used in a wide range of electronic application fields. The capacitor offers a temperature operating range between -25C to +85C, and a capacitance range of 0.1 - 4700µF. The UHE0J152MPT is also equipped with a safety discharge resistor and burst protection, which ensures the stored energy is safely discharged in the event of a overload.

Conclusion

The UHE0J152MPT Aluminum Electrolytic Capacitor is a versatile, long-lasting and reliable device, designed for a wide range of electronic applications. The capacitor is designed with a volumetric construction, which utilizes a two-layer construction of Aluminum and an electrolytic solution to provide electrical capacitance. The capacitor also offers a wide temperature operating range, and is equipped with a safety discharge resistor and burst protection, to ensure the stored energy is safely discharged when needed.
