Aluminum Electrolytic Capacitors are widely used in a variety of electronics and electric devices because of their characteristics such as their high capacitance in comparison to their size, low ESR, low dielectric losses, and long life span. MAL211651158E3 is an aluminum electrolytic capacitor with a 5.3mm diameter and 8.1mm in length. It has a rated capacitance of 470μF and a rated voltage of 12V. The MAL211651158E3 is a long life type, with a life rating of 5000hours at 120˚C. Other characteristics of the MAL211651158E3 include a rated ripple current of 0.50A and a ripple voltage of 120V.

The primary application field of the MAL211651158E3 is for smoothing and filtering applications such as power supplies and switching regulators. In these types of applications, the capacitor works to smooth out pulsed DC signals and reduce AC ripple voltage. It also works to provide energy storage on a DC power rail and to filter out noise and distortion. The capacitance of electrolytic capacitors is usually much larger in comparison to other types of capacitors, which makes them suitable for High-Frequency Noise Reduction (HFNR) applications.

The working principle of an electrolytic capacitor is based on the Helmholtz Double Layer Theory. This theory states that when a metal and an electrolyte (a conducting liquid) are placed in close proximity, a localized electric field is created around the metal surface. This field is the result of the capacitance that is generated between the metal and the electrolyte. The capacitance of the capacitor depends on the metal surface area, electrolyte permittivity, and the gap distance between the metal and the electrolyte. The electrolyte in an electrolytic capacitor is a solid electrolyte, usually an oxide or a polymer, that can store charge and is responsible for the low ESR of the capacitor.

The MAL211651158E3 is a radial-leaded type capacitor with two leads connected to the anode and cathode of the capacitor. The anode of the capacitor is typically made from aluminum, while the cathode is a solid electrolyte material. When a voltage is applied between the two leads, positively charged ions are attracted to the anode, forming a layer of positive ions. At the same time, negatively charged ions are attracted to the cathode, forming a layer of negative ions. This creates an opposing electric field which results in an increase of capacitance. This process is reversed when the voltage is removed, causing the capacitor to discharge.

The MAL211651158E3 has a range of performance advantages that make it an ideal choice for a wide variety of applications. Its high capacitance makes it suitable for filtering and smoothing applications, while its low ESR ensures that voltage fluctuations are minimized. Its long life rating guarantees reliable performance in the most demanding settings. As such, the MAL211651158E3 is an excellent choice for a variety of electronics and electric devices.
