Aluminum-Polymer Capacitors

EEF-SX0D471E4 application field and working principle

Aluminum-polymer capacitors are widely used in electrical engineering applications, especially in high-performance electronics due to their excellent capacitance and wide range of operating temperatures. The EEF-SX0D471E4 is one such type of capacitor that is used in a wide range of applications such as portable electronics, computer displays, storage and solar power systems, to name a few.This type of capacitor is a miniaturized version of the aluminum electrolytic capacitor, which is an electrical component that works similarly to other capacitors. The aluminum-polymer type differs, however, in its construction. It uses two thin aluminum foil electrodes with a highly conductive, electrolyte-impregnated, polymeric material as the dielectric. The resulting increase in capacitance and voltage rating allows it to be used in applications requiring a relatively high capacitance.The EEF-SX0D471E4 has a capacitance of 6.5µF and a rated voltage of 4 volts. It also has a low ESR of just 0.09 ohms and a ripple current rating of 11-125 mA depending on the temperature of the device.In terms of applications, the EEF-SX0D471E4 is mainly used in consumer electronic products such as portable DVD players, mobile phones, and digital cameras. It is also used in digital displays, LED lighting systems, automotive electronics, and audio systems. This type of capacitor is also used in certain microcontroller and digital signal processing (DSP) applications.When selecting aluminum-polymer capacitors, it is important to consider the environment in which the device will operate. This includes considerations such as temperature, vibration, and shock, as these can all affect the performance of the capacitor. Additionally, it is important to select a capacitor with the proper capacitance, voltage rating, and ripple current rating for the application.In terms of working principle, the EEF-SX0D471E4 consists of an electrolytic medium impregnated throughout a porous polymer. This electrolyte impregnation provides the desired level of electrical conduction so that the capacitor can store electrical energy between two metal plates. This stored energy allows the capacitor to act as a filter in the circuit, with the capacitor acting as a resistor. This in turn reduces the flow of electrical current and provides a smooth, regulated flow of current throughout the circuit.In conclusion, aluminum-polymer capacitors like the EEF-SX0D471E4 are increasingly being used in many electrical engineering applications. Their wide range of applications, excellent capacitance and voltage ratings, and low ESR make them ideal for many consumer electronics, automotive electronics, audio systems, and other applications. In order to ensure optimum performance, it is important to take into consideration the environment of the application and to select a capacitor with the proper capacitance and voltage ratings.
