Aluminum electrolytic capacitors are widely used and applied in many areas, from consumer electronics to military and aerospace applications. With their relatively low cost, high energy storage capacity, wide temperature range, and long operational life, they are ideally suited for those applications that require a large amount of electrical energy. The ESMG451ELLR47MJC5S is a capacitor designed for high-capacitance, low-voltage-drop applications.

The main components of the ESMG451ELLR47MJC5S are an aluminum can, a spiral wrap of electrolytic paper, and tin-plated electrical leads, all of which are housed in a hermetically sealed metal can. The aluminum can acts as the anode while the tin-plated electrical leads act as the cathode. The capacitance is varied by adjusting the wrap of the electrolytic paper, with tighter wraps providing higher capacitance and vice versa.

The primary application for the ESMG451ELLR47MJC5S is as a filter capacitor in consumer electronics, particularly television and audio equipment. As the capacitor stores electric charge, it limits the amount of electric current that can pass through it and thus prevents fluctuations in power. As the capacitor discharges, it provides a buffering effect, smoothing out sudden surges in power that could otherwise cause damage to sensitive components. The ESMG451ELLR47MJC5S is also commonly used in electric motor applications and battery charging systems as a buffering capacitor.

The principle of operation for the ESMG451ELLR47MJC5S is straightforward. When an external electric source is connected to the capacitor, electric current flows through the electrolytic paper spiral wrap and the electrolyte, creating a charge differential between the anode and cathode. The amount of electrical energy that can be stored by the capacitor is determined by its capacitance, which is determined by the wrap of the electrolytic paper.

When the electric current is removed and the capacitor is placed under zero voltage, the charge stored in the capacitor begins to dissipate through the cathode lead. As the electric charge dissipates, the capacitor is said to be discharging and begins to lose its capacitance. The rate of discharge is determined by the internal resistance of the capacitor, which is less than one ohm.

The ESMG451ELLR47MJC5S is a specially designed capacitor that has been optimized for capacitor applications. Its high capacitance and low voltage drop make it ideal for use in numerous electronics applications. It is also designed to withstand the rigors of high temperature and long-term use, making it a reliable and suitable choice for many electrical projects.
