Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, or electrolytic capacitors, are the most widely used capacitors. These capacitors are polarized and consist of an anode aluminum foil with an oxidized surface layer and a large number of dielectric paper layers as the cathode. The anode and cathode foil are separated by a liquid electrolyte. The dielectric paper is initially non-conductive due to insulating layers, but when an electrical field is applied, the oxide coating breakdown and current passes through the oxide layer. The current creates positive ions in the electrolyte which act as a conductor, thus allowing charge flow.

450LSQ6800M90X151 application field and working principle

The 450LSQ6800M90X151 is an aluminum electrolytic capacitor. It is a low profile, high temperature, and long life capacitor used for high voltage applications such as power supplies, pumps, motors, and other DC to AC output converters. It has the capability to handle ripple currents at high frequencies and voltages up to 450 volts. It has an insulation resistance of at least 100MΩ (µF) at 20°C, and a dielectric strength of at least 2000V (DC).

The working principle of the 450LSQ6800M90X151 is based on Faraday’s law of induction. When an AC waveform is applied across the capacitor, an alternating current flows through it, creating an electric field that causes an increase or decrease in the potential energy stored across the plates. The electrical field causes a displacement of charged particles, changing the electrical state of the capacitor, and ultimately changing the voltage. The current passing through the capacitor is directly proportional to the rate of change of the voltage.

The 450LSQ6800M90X151 is designed for use in a number of applications such as motor drives, AC inverters, home electronics, and UPS systems. Because of its high temperature and long life characteristics, it is best suited for long-term, large load applications such as pumps and motors. The high voltage and ripple current capability make it suitable for DC to AC output converters. It also has the advantage of being able to handle extreme temperature variations due to its robust construction.

Since the 450LSQ6800M90X151 is an aluminum electrolytic capacitor, it must be subjected to a certain amount of stress in order to prevent any premature malfunctioning. An excessive amount of stress can cause the capacitor to fail or cause a ripple or spark. This can potentially damage the system that the capacitor is connected. Therefore, it is important to use the appropriate capacitance rating for the intended application. It is also recommended to use a properly sized heat sink when using the capacitor in order to reduce the heat generated by the capacitor.
