Aluminum - Polymer Capacitors are a type of capacitors that are made up of an anode aluminum foil, a dielectric layer and a cathodic aluminum foil. They are used in many applications and are known for their stability and high capacitance. The ESRD4R7M12R is a popular aluminum-polymer capacitor that is used in a wide range of applications. This article will discuss the application field and working principle of the ESRD4R7M12R.

Application Field

The ESRD4R7M12R aluminum-polymer capacitor is commonly used in electronic devices and circuits that require a high level of stability and capacitance. Due to its high capacitance and low ESR (Equivalent Series Resistance), the ESRD4R7M12R is used in a variety of power supply, high-frequency, voltage stabilizing and filtering applications. With its low ESR, it provides a very stable voltage to power various electronic components. It is also able to withstand high surge currents and is a good choice for power supply applications.

The ESRD4R7M12R also has a wide range of uses in the automotive industry. It is used in a variety of automotive circuits such as voltage regulators, alternator control unit, airbag control unit and power inverter circuits. It is also used in automotive radio antenna systems and in the Bluetooth communication units. In addition, the ESRD4R7M12R is widely used in the telecommunications industry.

Working Principle

The ESRD4R7M12R aluminum-polymer capacitor is composed of an anode aluminum foil and a cathodic aluminum foil. In between the two foils is a dielectric layer that consists of a variety of chemical compounds, such as polyethylene, polypropylene, and polyphenylene sulfide. The dielectric layer acts as an insulating material, preventing the formation of a short circuit between the two foils.

The ESRD4R7M12R aluminum-polymer capacitor works by creating a charge storage effect. When a positive charge is applied to the anode, it causes electrons to accumulate on the surface of the aluminum foil. This accumulation of electrons creates a space charge effect, which increases the capacitance of the capacitor. When a negative charge is applied to the cathodic aluminum foil, it causes electrons to be removed from the surface of the aluminum foil. This causes the capacitance to decrease.

The ESRD4R7M12R aluminum-polymer capacitor is a stable and reliable capacitor that can handle high currents and withstands high surge currents. It is ideal for power supply, high-frequency, voltage stabilizing and filtering applications. Its ability to function reliably in a wide range of temperatures makes it a great choice for many applications.
