Aluminum electrolytic capacitors are a type of capacitors that are based on electrolytic chemistry and use a porous layer of an aluminum oxide as its dielectric. These capacitors offer the highest capacitance values for a given physical size and produce high capacitance values compared to all other capacitor types. The EKXJ251ELL820MJ45S is a type of surface mount aluminum electrolytic capacitor that offers high capacitance, high voltage, and long life values.

Application Field

The EKXJ251ELL820MJ45S capacitor is used in a variety of applications that require high voltage, high capacitance, and long life values. These capacitors are often used in power supplies, motor drive circuits, and other power-related applications. They are also used in automotive and aviation applications as well as in audio and video equipment.

Working Principle

The EKXJ251ELL820MJ45S capacitor works by using a voltage drop across the dielectric, which is made of aluminum oxide, to increase the capacitance of the capacitor. The capacitance of the capacitor will depend on the voltage across the capacitor, the thickness of the dielectric, and the surface area of the dielectric. The thicker the dielectric, the higher the capacitance value that can be achieved.

The EKXJ251ELL820MJ45S capacitor works by using a current to pass through the capacitor when a voltage is applied to the two electrodes. This current will charge up the capacitor’s dielectric layer. The voltage across the dielectric will cause the dielectric to become polarized. This polarization of the dielectric will increase the capacitance, causing the voltage to drop across the capacitor. The amount of charge stored in the capacitor will increase until it reaches its maximum value.

The EKXJ251ELL820MJ45S capacitor also has a low leakage current and a low equivalent series resistance (ESR). This reduces power loss, which increases efficiency and improves the performance of the capacitor. The ESR also ensures that the capacitor maintains its capacitance value even when a voltage is applied to the terminals.

The EKXJ251ELL820MJ45S capacitor also has a high temperature tolerance and a long life expectancy. This makes it an excellent choice for power-related applications where high voltages and long life are required. In addition, the capacitor is resistant to electrical noise and static but is highly sensitive to mechanical shock, which can cause damage if the capacitor is not handled properly.

The EKXJ251ELL820MJ45S capacitor is an excellent choice for a variety of power-related applications that require high capacitance, high voltage, and long life values. It has a high temperature tolerance, low ESR, and is highly reliable. In addition, it is resistant to electrical noise and static, making it an ideal choice for applications where high reliability and long life are needed.
