Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are passive electronic components used in many parts of the electrical circuit. They work by storing electrical energy in the form of an electric field, which can be used for many different types of electric current. In addition to their storage function, AECs also serve an essential role in the operation of electrical equipment, including signal processing, voltage buffering, and filtering.

The MAL213651222E3 Aluminium Electrolytic Capacitor is a product from the well-known and reliable TDK Corporation. The MAL213651222E3 capacitor is designed for a variety of applications in the industrial, automotive and consumer markets. It has a frequency range of up to 400 Hz with a rated temperature range of -40 to +85 °C. It is also equipped with a low ESR and High Ripple Current Capacitance as well as a High Stability DC Voltage.

The MAL213651222E3 is based on aluminum electrolytic and uses traditional, well established technology. It\'s a radial leaded aluminum electrolytic capacitor with a non-solid electrolyte which allows for enhanced properties such as high storage, low ESR, high ripple current capability and high insulation resistance. It\'s designed for use in low to high frequency applications, as well as ambient temperature applications. It is also equipped with a built in surge voltage protection that prevents failure caused by high voltage spikes.

The MAL213651222E3 is a polarized capacitor, meaning that the correct polarity or voltage must be applied when connecting it to the circuit. The polarity of the capacitor is marked on the can or shell body by a stripe or dot to indicate the correct polarity for connecting the capacitor. This is important since reverse applied voltages may cause damage to the capacitor by heating up its electrodes.

The MAL213651222E3 capacitor is composed of a pair of high-conductivity plates, separated by an anode material. The anode material typically consists of a porous aluminum oxide film, containing an adsorbed electrolyte. When a voltage is applied across the capacitor\'s terminals, the positive and negative plates develop charges with respective polarizations of opposite sign. An electric field is formed between the plates, resulting in the accumulation of charge. This effect is known as capacitance.

The polarization of the capacitor\'s terminals affects its capacitance value, by changing the distance between the plates, as well as the dielectric constant of the medium between them. Depending on the applied voltage, the polarized capacitor can provide currents or act as a voltage follower in a reverse biased condition. With such properties, the MAL213651222E3 can be used in a variety of circuit applications, including power supply filtering, signal processing, signal mixing, measuring instruments, tone control and step-up, among others.

In conclusion, the MAL213651222E3 aluminum electrolytic capacitor is a reliable device that offers a wide range of applications in the industrial, automotive and consumer markets. Capable of storing electrical charge and withstanding high voltage spikes, this capacitor can be a valuable addition to a number of circuits.
