Aluminum electrolytic capacitors are used in a variety of applications, including power supplies, microwave ovens, motors, AC and DC circuits, and for high frequency signals. The EMVA350 ADA4R7MD55G (herein referred to as “ADA4”) is an aluminum electrolytic capacitor manufactured by Matsushita. It is a general-purpose capacitor and is used most often in high frequency applications such as oscillators, communications circuits, and power filters. The ADA4 is a radial lead device with a cylindrical profile and pins measuring 4mm in diameter and 7mm in length. It features a wide temperature range and can be used in temperatures between -40°C to +105°C. The casing is made of aluminum and the cap is made of plastic. The structure of the ADA4 is designed to provide high stability and is resistant to external vibration, shocks, and thermal stresses. The ADA4 is designed to handle a high voltage, with the rated operating temperature ranging from 6.3V to 200V depending on the specific model. It has a maximum ripple current rating of 20mA and an equivalent series resistance (ESR) of 1.4 ohms. The capacitance range for the ADA4 is from 4.7uF to 47uF. There are three characteristics available; standard, low impedance, and high capacitance. The working principle of aluminum electrolytic capacitors is based on the fact that aluminum foil can be polarized by passing a positive or negative electric current through it. This polarization creates an electrical field that allows current to flow between the two aluminum plates, creating an electric charge. The plates are separated by a dielectric material (sometimes referred to as the “electrolyte”) which keeps the charge from dissipating. When a voltage is applied to the capacitor, the electric field increases the charge stored in the capacitor, and when the voltage is removed, the charge dissipates.The ADA4 is a reliable and stable device for applications that require a low ESR and a wide temperature range. It is highly resistant to vibration and shock, making it a great choice for use in harsh environments. The device is also able to withstand up to 200V, which makes it suitable for high voltages applications. The ADA4 is used for high frequency applications such as oscillators, communications circuits, and power filters. Additionally, the high capacitance range makes it well suited for use in DC-DC power converters, AC line filters, and voltage multipliers. In conclusion, the ADA4 is an aluminum electrolytic capacitor that offers a high voltage capacity, a wide temperature range, and low ESR. It is well suited for use in many high frequency applications, especially those that require a high capacitance rating. It is also highly resistant to vibration and shock, making it a reliable and stable device for use in harsh environments.
