Aluminum-Polymer Capacitors, such as the MAL218197502E3, are special components that have become increasingly popular in both consumer and industrial applications due to their low cost, high capacitance and excellent electrical performance. The capacitors are most commonly used in circuits where high capacitance is required in a small package, such as power systems and consumer electronics. In this article, we will discuss the application field and working principle of the MAL218197502E3 Aluminum-Polymer Capacitor.

The MAL218197502E3 Aluminum-Polymer Capacitor is a surface-mount, four-terminal, non-polar electrolytic capacitor. It is manufactured by Mitsubishi Electric and is available in a range of capacitance values from 0.01uf to 7.5uf. The capacitors feature a cylindrical aluminum case, which contains a thin layer of polyurethane soaked in an electrolyte solution. The aluminum case is encased in a thin polyurethane film, which serves both as a conduit for the electrolyte and as a barrier to prevent leakage. The four terminals of the capacitor are connected to the aluminum case and the polyurethane film, forming an effective electrical connection.

The MAL218197502E3 Aluminum-Polymer Capacitor is ideal for a variety of applications, including power supplies, automotive electronics, and consumer electronics. In power supply applications, the aluminum-polymer capacitors are used to store and filter energy, reduce electromagnetic interference, and filter the output of AC and DC power. The capacitors are also used to filter and regulate the voltage in automotive systems, such as electronic fuel injection and electronic ignition. In consumer electronics, the capacitors are used to filter out audio noise and reduce electromagnetic interference. The capacitors are also used in communication circuits, such as PC modems and cell phones.

The MAL218197502E3 Aluminum-Polymer Capacitor works on the principle of electrolytic capacitance. When a voltage is applied across the two terminals of the capacitor, a layer of electrolyte is formed and a charge is stored in the capacitor. The capacitance of the capacitor is determined by the thickness of the polyurethane film, the size and shape of the aluminum case, and the relation between the two. The capacitance is also determined by the type of electrolyte used, as different electrolytes have different dielectric constants.

The MAL218197502E3 Aluminum-Polymer Capacitor is a cost-effective, high-performance capacitor that is well-suited for a wide range of applications. It can be used in power supplies, automotive electronics, and consumer electronics, as well as communication and audio circuits. The capacitors are available in a range of capacitance values, and the capacitance can be adjusted based on the type of electrolyte used. The aluminum case and polyurethane film provide excellent electrical insulation, preventing leakage and minimizing distortion. The capacitor’s working principle is based on the principle of electrolytic capacitance, which allows the capacitor to store and filter energy.
