Aluminum electrolytic capacitors are of relevance to varied applications and environments, primarily because of the flexibility of their construction. This flexibility and the range of electrical and mechanical parameters is what makes them the go-to choice for electric and electronic systems, from power supplies and drives to measurement and control systems. The EEV-FK1C152Q is a popular aluminum electrolytic capacitor, and is a great example of the technology underlying these components.

Overview

The EEV-FK1C152Q capacitor is an aluminum electrolytic capacitor with a capacitance rating of 150 μF and a working voltage of 250 V. It employs aluminum anode foils, which makes it suitable for applications requiring long shelf life and high ripple current capabilities. It also boasts a wide temperature range of -25°C to 85°C, low equivalent series resistance (ESR), and short mounting time.

Design and Features

The EEV-FK1C152Q capacitor is a cylindrical capacitor with a welded case and a cover. The two conducting electrodes are insulated from each other by separators containing the electrolyte. The separator also acts as a dielectric and provides insulation between the anode and the cathode. The capacitor is usually characterized by its capacitance and the maximum voltage that can be applied across its terminals. Other characteristics include ESR, maximum ripple current, temperature range, and lifetime.

Applications

Aluminum electrolytic capacitors like the EEV-FK1C152Q find its widespread use in various technical fields, such as power electronics, measurement and control, power supplies, video receivers, and audio circuits. This capacitor is especially suitable for pulse applications and is most commonly used as a filter capacitor in power supplies, thus eliminating high-frequency noise or ripple. It is also used in the primary filters of DC-DC converters, as a bypass capacitor in radio circuits, as a DC power supply in audio systems, and as a ceramic capacitor in various electronic devices.

Working Principle

An aluminum electrolytic capacitor is a type of capacitor that uses an electrolyte to create a highly conductive layer on an anode. This increases the capacitance and allows the device to store an electrical charge. The electrolyte typically used is an aqueous solution of ammonium borate and lactic acid, but the exact composition of the electrolyte varies depending on the exact capacitor design and intended use. When a voltage is applied across the two terminals of the capacitor, electric current will flow and form the electrolyte layer on the anode. The electrolyte then serves as an electrical insulator, preventing current from flowing when the voltage is reversed.

Conclusion

The EEV-FK1C152Q capacitor is a highly versatile aluminum electrolytic capacitor and is widely used in various electronic applications. Its high capacitance and low ESR enable it to perform efficiently, especially in pulse applications, along with the long shelf life and the wide temperature range. These features, along with its ease of mounting, make it ideal for use in a wide range of electronic devices.
