Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, or simply called electrolytic capacitors, are passive components used in electronics, primarily for filtering and energy storage applications. They\'re constructed with a metal case, several metallic plates, and filled with an electrolytic compound. Due to their low cost, long life spans, and wide range of dissipation factors, aluminum electrolytic capacitors are the most popular type of capacitors in the industry.

The 250PK4.7MEFCT16.3X11 is a type of aluminum electrolytic capacitors that integrates various features into a compact and reliable design. It features a four-terminal lead configuration, a low equivalent series resistance (ESR) of 4.7 m ohm at 100 KHz, a high-temperature operating temperature of 16.3 Degree C, a maximum rated voltage of 250 volts, and a rated capacitance of 11 Farads.

Application Field

This type of capacitors serves as an effective solution for industrial components subject to high humidity environment as they are particularly stable at high temperatures. Additionally, they have also been used in aerospace and military applications, for which they must meet certain precision and reliability requirements. In terms of consumer electronics, aluminum electrolytic capacitors are also used widely in computers, alarm systems, and other electronic devices.

Working Principle

The basic principle of aluminum electrolytic capacitors function involves multiple alternating layers of an electrolyte, an anode, and a cathode. When a voltage is applied across these plates, a thin layer of dielectric material is formed on the anode due to the oxidation reaction of the electrolyte. This dielectric material provides the capacitance of the device and stores electrical energy.

This type of capacitors are constructed with a cylindrical metal housing which seals the active components. The housing is filled with an electrolyte, such as a solution of micronized carbon powder and paste, to provide an electrical connection between the multi-level, metallized plates. The different metals in the plates create an electrochemical reaction when voltage is applied, and this reaction forms a dielectric material. This material works to separate the plates in the capacitor, causing it to store energy more efficiently and for a longer period of time, and also acts as insulation between the anode and the cathode.
