Aluminum electrolytic capacitors are electrical devices mainly consisting of an anode made of aluminum foil with an etched surface, a paper separator soaked in electrolyte, and a cathode of aluminum oxide. They are used to store energy, provide smoothing of power supplies, and filter high and low frequencies. The EKZH250ETD471MJC5S is an example of such a device.

Application Field

Capacitors in general are found in a range of applications, from simple circuits where single capacitors are used to store a single pulse of charge, to more complex circuits where multiple capacitors are connected in configuration to create filters.The EKZH250ETD471MJC5S is an aluminum electrolytic capacitor with a low equivalent series resistance (ESR) design. Low ESR design makes it suitable for use in power circuits, where it can be used to suppress transients, store energy, act as RLC tuning and damping elements, and provide filtering for signals. Its characteristics make it particularly suitable for use in applications such as power supplies, low noise amplifiers, and voltage regulators, where low ESR is an important factor.

Working Principle

The basic ingredients in an aluminum electrolytic capacitor consist of an anode made of aluminum foil with an etched surface, a paper separator soaked in electrolyte, and a cathode made of aluminum oxide. The etched surface of the anode increases the internal surface area, which in turn increases the capacitance of the device. When a voltage is applied to the capacitor, a electric field is formed between the anode and the cathode, establishing an electric charge along the surface of the capacitor. As more charge accumulates on the surface of the capacitor, electric field strength increases, which in turns decreases further capacitance.These capacitors feature a solid electrolyte instead of a liquid one which reduces the amount of capacitance loss. The construction of these capacitors also makes them more tolerant to high temperatures and vibration compared to other types of capacitors.

Conclusion

The EKZH250ETD471MJC5S is an aluminum electrolytic capacitor featuring a low equivalent series resistance (ESR) design. It is suitable for applications such as power supplies, low noise amplifiers, and voltage regulators, where low ESR is an important factor.The capacitance of the device is determined by the size and shape of the anode and cathode electrodes, and the electrolyte in between them. The construction of these capacitors also makes them more tolerant to high temperatures and vibration compared to other types of capacitors. This makes the EKZH250ETD471MJC5S capacitor a suitable choice for applications that need a combination of high capacitance and reliable performance.
