Aluminum - Polymer Capacitors
The EEF-HX0E471R4 is a type of aluminum-polymer capacitor and is specifically designed to enable the miniaturization of printed circuit boards (PCBs). It is characterized by a small size and low equivalent series resistance (ESR), as well as a high capacitance.
Application Fields of Aluminum - Polymer Capacitors
The EEF-HX0E471R4 can be used in a wide range of applications, including electronic equipment such as mobile devices, digital cameras, GPS devices, portable audio equipment, and portable medical equipment. Because of its small size and low equivalent series resistance, the EEF-HX0E471R4 is an ideal choice for applications that require miniaturization, reduced power consumption, and space savings.
Working Principle of Aluminum-Polymer Capacitors
The EEF-HX0E471R4 is an aluminum-polymer capacitor and works using a specific electrochemical principle. These capacitors use a layered structure consisting of a solid polymer dielectric film and two electrodes. One of the electrodes is a porous aluminum layer that serves as a separator between the two films. The other electrode is composed of a metal-oxide or carbon-polymer composite material.
When a voltage is applied to an aluminum-polymer capacitor, the porous aluminum layer allows the ions in the electrolyte to be attracted to the other electrode. The ionic conductivity between the two electrodes forms an electric double-layer, which gives the EEF-HX0E471R4 its capacitance. This capacitance is determined by the area of the electrodes and the distance between them.
Conclusion
The EEF-HX0E471R4 is a type of aluminum-polymer capacitor specifically designed for use in miniaturized PCBs. It is characterized by a small size and low equivalent series resistance, as well as a high capacitance. It is ideal for applications that require miniaturization, reduced power consumption, and space savings. It works by forming an electric double-layer due to the ionic conductivity between two electrodes, thus providing the EEF-HX0E471R4 with its capacitance.
