Aluminum electrolytic capacitors are versatile electrical components used to store electrical energy. The MAL211919479E3 is one type of aluminum electrolytic capacitor. It is a radial-lead type and is intended for use in general commercial and industrial applications. This capacitor is rated for maximum working voltage up to 200V, maximum temperature up to 105°C, and can handle a maximum ripple current up to 4.0A.

The MAL211919479E3 aluminum electrolytic capacitor is mainly designed for applications such as DC filters, DC blocking, and suppression of high-frequency noise. This type of capacitor is also well suited for applications such as AC/DC power supplies, audio amplifiers, power transistors, and automotive electric systems.

The working principle of an aluminum electrolytic capacitor is quite simple. In an electrolyte solution, an anode of aluminum is immersed, and the anode is then coated with an oxide film. The anode and the electrolyte solution form a pair of electrodes in the capacitor. A DC voltage is applied to the external terminals of the capacitor, which causes electrons on the anode to move to the cathode. This process forms a charge between the electrodes, creating a static electric field in the gap between them. This static electric field stores energy like a battery, enabling the capacitor to store an electrical charge.

When a alternating current signal is applied to the capacitor terminals, the electrons will flow back and forth across the oxide layer, allowing the capacitor to act as a low-pass filter, blocking low-frequency DC signals and passing AC signals. This makes aluminum electrolytic capacitors an ideal choice for applications such as power supplies and audio amplifiers, where a smooth output is required.

Aluminum electrolytic capacitors are a low-cost, reliable solution for electrical applications and the MAL211919479E3 is no exception. Due to its high ripple current ratings and stable temperature range, it is well suited for many applications, from audio amplification to DC power supplies. Its robust construction makes it particularly resistant to mechanical shock and vibration, making it a reliable choice for all sorts of applications.
