Aluminum-Polymer Capacitors (APCs) are a type of technology used in high-frequency applications, enabling products such as ESRD221M0EXR (ESRD) to be used in high-end, high-performance products. This article will discuss the application field and working principle of ESRD221M0EXR.

APCs are a combination of layers of Materials, most commonly including a metal layer and an insulating polymer layer. This structure allows them to be employed in circuits where both high voltage and high frequencies are needed. These capacitors are good at filtering signals, providing improved signal quality and supply reliability, as well as higher levels of performance. They are also ideal for reducing size due to their small form factor.

The ESRD221M0EXR is an aluminum-polymer capacitor with a high capacitance (22000uF) and low ESR (0.0035 ohms). It is specifically designed to meet the demands of high-efficiency applications and to deliver reliable performance in power circuits. This capacitor can operate at a wide temperature range from -55°C to +85°C and has a high ripple current of 13.5A. Its capacitance tolerance is ± 20%.

The working principle of the ESRD221M0EXR is based on the capacitance of the two layers of materials. When a voltage is applied to the two layers, an electric field is created between them. This field induces an electric charge on the plates, resulting in the capacitor being charged. The capacitor then stores energy in the form of an electric field between the two layers. This field can then be discharged, releasing the energy stored in the capacitor.

The ESRD221M0EXR capacitor is primarily used in high-end power supply and power conversion applications. It is well suited for applications such as DC-DC converters, voltage regulators, switching power supplies, and other high-efficiency, high-power applications. It is also commonly used in automotive applications such as fuel injection systems and alternators. In these applications, its high capacitance, low ESR, wide temperature range, and high ripple current make it an ideal choice.

In conclusion, ESRD221M0EXR is an aluminum-polymer capacitor used in high-frequency applications. It has a high capacitance, low ESR, and wide temperature range, making it ideal for power supply, power conversion, and automotive applications. Its working principle is based on the capacitance of the two layers of materials, which when a voltage is applied, creates an electric field and stores energy in the form of an electric field.
