Aluminum electrolytic capacitors are capacitors that make use of an electrolytic material which results in a population of smaller capacitors internally connected in parallel. The MAL216036102E3 capacitor is a standard type of radial lead aluminum electrolytic capacitor made by TDK that are typically used to store energy for a momentary peak load in a power supply system, filter voltage ripples in DC/DC converters, and for timing circuits. The capacitor exhibits a high capacitance, even at high frequencies, long-term reliability, and low equivalent series resistance (ESR). The MAL216036102E3 has a variety of applications in automotive, consumer electronics, and industrial-related fields. In automotive, it is used in car navigation systems, ABS brakes, and safety systems. In consumer electronics, it can be used for laptop computer voltage protection, audio speaker crossover coils, and mobile phone home-charging switches. In industrial fields, it can be used for security electronic doors, cash registers, and power tools.

The working principle of the MAL216036102E3 can be summarized in the following order of steps. First, a voltage difference between the two plates of the aluminum electrolytic capacitor is created by charging the capacitor. This voltage difference attracts the electrically charged electrolyte molecules to the plates, resulting in a small number of molecules adhering to each plate. The electrolyte molecules neutralize the excess charge on each plate, allowing for a current flow between the two plates. The charges on the electrolyte molecules create a capacitance of the aluminum electrolytic capacitor.

The MAL216036102E3 is made up of an aluminum can, a polyester, and an electrolyte. The aluminum can is made of a conductive aluminum foil, and serves as the electrodes of the capacitor. The polyester film will separate the aluminum can into two sections, and will also function as an insulator. The electrolyte will then be filled into the capacitor, creating a dynamic, charged, yet insulated capacitor. When an alternating current is connected to the capacitor, current can flow back and forth between the two electrodes. In each section of the capacitor, the current will be drawn through the electrolyte molecules, allowing for charge to be stored and discharged from the capacitor. The capacitance of the aluminum electrolytic capacitor is determined by the structure of the capacitor, the dielectric constant, the temperature, and the amount of electrolyte. The dielectric constant of the aluminum foil determines the capacitance in the upper frequency range. The capacitance decreases as frequency increases, allowing for a frequency-dependent impedance. Temperature and the amount of electrolyte also have a strong influence on the capacitance of the aluminum electrolytic capacitor. As temperature increases, the capacitance decreases due to the decrease in the ionic mobility of the electrolyte. Likewise, the amount of electrolyte also affects the capacitance. As the amount of electrolyte increases, the capacitance also increases as more liquid between the electrodes is available to bear charges.

The MAL216036102E3 aluminum electrolytic capacitor has a wide range of applications in automotive, consumer electronics, and industrial fields, and is used to store energy for momentary peak loads, filter voltage ripples, and for timing circuits. The capacitor is made up of an aluminum can, a polyester film, and an electrolyte, and its capacitance is determined by the dielectric constant, temperature, and amount of electrolytic material.
