Aluminum-polymer capacitors, such as 337XMPL002MG28, are a type of capacitor consisting of two physical layers, one made of aluminum and the other made of a dielectric polymer. These types of capacitors have the advantage of being lightweight and low in cost, while offering a low ESR (equivalent series resistance) and higher volumetric efficiency than other types of capacitors.The most common application for 337XMPL002MG28 and other aluminum-polymer capacitors is in portable electronic devices such as cell phones, digital still cameras, MP3 players and laptop computers. They are also used in automotive electronic devices, electric drives and power systems, industrial motors, and other applications requiring high ripple capability or high capacitance value.The working principle behind aluminum-polymer capacitors is based on the electric field effect. When a voltage is applied across the capacitor, electric charges flow from one electrode to the other, creating an electric field between them. This electric field causes an ionic conduction across the gap between the two electrodes, thus allowing electrons to move between them. This electron movement creates a current, and it is this current that is measured as capacitance.Generally, 337XMPL002MG28 and other aluminum-polymer capacitors have a higher ripple current capability than other types of capacitors. This is because the electric fields generated by the electrodes cause the ions to move back and forth more frequently, thus creating a higher frequency ripple effect. This makes them better suited for applications that require a high ripple current.Additionally, aluminum-polymer capacitors have a wide range of temperature coefficient, meaning that their capacitance does not change significantly with temperature changes. This makes them well suited for use in environments with large temperature fluctuations as well as high humidity levels.Aluminum-polymer capacitors, such as 337XMPL002MG28, are a cost-effective and lightweight solution for portable electronic devices and other applications that require high ripple current or low ESR. They are capable of withstanding high temperature ratings and provide a wide range of temperature coefficient, making them ideal for use in a variety of applications.
