Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a wide range of electronic applications. This type of capacitor utilizes an electrolyte, usually composed of an aqueous solution of potassium hydroxide or other organic solvents, in order to store a charge. This type of capacitor is constructed of two aluminum plates, separated by a thin dielectric of an electrolyte material.

The EKXJ351ELL470MJ40S is an aluminum electrolytic capacitor developed by Panasonic. It has a rated voltage range of 4 to 60V and a capacitance range of 0.01 to 1uF. The temperature range of the capacitor is -25 degrees C to 85 degrees C, and the dielectric strength is 2000Vac/2s.

Application Field

Due to its low cost and wide range of applications, aluminum electrolytic capacitors such as the EKXJ351ELL470MJ40S are extensively used in many electronic devices. In addition to basic electronic applications, they are also often used in more specialist applications such as power supplies, rectifiers, DC/DC converters, and signal filters. From toys to medical and industrial equipment, aluminum electrolytic capacitors are likely to be found.

Working Principle

Aluminum electrolytic capacitors work by storing the charge in the electrolyte. This allows for a much larger capacitance than would be possible with other types of capacitor. The charge is stored by the presence of ions in the electrolyte. When a voltage is applied to the electrode plates, the ions move towards the positive electrode, where they become trapped in the polyethylene oxide of the electrolyte.

The amount of charge stored on the capacitor is limited by the equivalent series resistance (ESR) of the capacitor. This is a measure of the resistance of the circuit as the current passes through the capacitor. The ESR of the EKXJ351ELL470MJ40S is rated at 1.2 ohms, which indicates that the capacitor is able to store a substantial amount of charge.

The temperature coefficient of the capacitor is also important for determining its performance. The EKXJ351ELL470MJ40S has a temperature coefficient of ± 15%. This means that the capacitance of the capacitor will vary by 15% over the rated temperature range of the capacitor.

Aluminum electrolytic capacitors such as the EKXJ351ELL470MJ40S offer a reliable and low-cost solution for a variety of applications. Their main advantage over other types of capacitor is their high capacitance and low ESR, which make them suitable for use in many situations where other capacitors would not be suitable.
