Aluminum-polymer capacitors, also known as Aluminium Polymer Capacitor (APC), represent a relatively new technology to the electronics industry. The ECG-C1CB4R7R is an aluminum-polymer capacitor manufactured by Electrochemical Group (ECG) and provides a broad range of features to meet any user requirements. This capacitor is characterized by its low ESR (Equivalent Series Resistance), low ESL (Equivalent Series Inductance) and high capacitance. In this article, we will briefly discuss the application field of the ECG-C1CB4R7R and its working principle.

Application Field: The ECG-C1CB4R7R capacitor is ideal for a variety of applications where high capacitance and low inductance is required such as switching power supplies, dc-to-dc power converters and commonly used to reduce peak currents, increase the filtering of high frequency noise and can operate in temperatures up to 105°C. Moreover, due to its electrical characteristics and wide operating temperature range, this capacitor is suitable for use in automotive, medical and industrial applications as well as in any kind of high-frequency circuit.

Working Principle: The ECG-C1CB4R7R is an aluminum-polymer capacitor designed to provide high capacitance, low ESR/ESL and high temperature performance without sacrificing voltage or longevity in the application. This capacitor utilizes an anodized aluminum foil, special dielectric film, silver-coated terminal electrodes and an outer casing of epoxy resin. As the electrical field in the capacitor increases, the anode aluminum foil forms a barrier to leakage current flow, thereby maintaining the capacitance over a greater range of input voltage. The dielectric film serves as the insulation layer between the anode and the cathode end of the capacitor. The special polymer film works by controlling the movement of ions and slowing the depletion of the dielectric film. This film is also designed to absorb and dissipate any sudden surges of heat. The silver-coated terminal electrodes allow for efficient current conduction and assist in the reduction of losses because of their high conductivity. Finally, the epoxy resin outer casing provides protection and supports physical stability during temperature and vibration extremes. Overall, the combination of these components helps to increase the long-term reliability, durability and lifespan of the ECG-C1CB4R7R.

In conclusion, the ECG-C1CB4R7R aluminum-polymer capacitor offers a broad range of features and benefits to users. This includes a low ESR, low ESL, high capacitance, wide operating temperature range, low impedance, and high temperature performance. The combination of components in the a-polymer capacitor assists with the protection and reliability over a longer period of time. As a result, this capacitor is ideal for use of in a variety of applications, including switching power supplies and dc-to-dc converters.
