Aluminum Electrolytic Capacitors

604D820F200GJ7 application field and working principle

Aluminum electrolytic capacitors are a type of capacitors with excellent performance such as large capacitance, small size, good frequency characteristics, and low temperature coefficient. It is widely used in various electronic products.

604D820F200GJ7, the full name of 604D Series Aluminum Electrolytic Capacitors, is a type of radial lead, snap-in aluminum electrolytic capacitor. It has higher performance than 603D capacitor and its working temperature range is wider. It usually applies for such a wide range of industry areas such as industrial, commercial, consumer, automotive, military and aerospace.

Therefore, 604D820F200GJ7 can be used in large-scale integrated circuits, LCD screens and plasma screens that require high frequency response. Industrial machines, such as nuclear reactors, hydroelectric power stations, coal mine hoists, steam turbine reducers, etc., all need 604D820F200GJ7, since its low temperature coefficient and superior frequency stability are very suitable for the stable and fast operation of these mechanical components.

In addition to the above applications, 604D820F200GJ7 is also widely used in many consumer electronic products, such as audio equipment, power monitors, motor controllers, wireless systems, laptop computers, amplifiers, etc.

Although the overall structure of electrolytic capacitors is similar to that of general capacitors, the electrolytic capacitors have two layers of aluminum foil with a layer of insulating film in between. The electrolyte coating layer is attached to one of the two aluminum foil layers, forming an anode pole of the capacitor, and the insulating film plays the role of separating anode and cathode.

The electrolyte used in the electrolytic capacitor is usually an aqueous solution of a metal salt, such as aluminum chloride or potassium chloride. When an electric potential is applied, positive ions pass through the electrolyte from one electrode plate to the other, forming a metal film (called anodic membrane) which provides the high capacitance typical of electrolytic capacitors.

The material of inner electrode layer of 604D820F200GJ7 is aluminum foil, the thickness of the aluminum material is 18μm, with snap-in locking type design, has better buckling strength, it can meet the requirement of components with high vibration and shock, so as to ensure the service life of electronic products.

By comparison, it is easy to see that electrolytic capacitors have higher capacitance than other types of capacitors. Due to the special structure of the electrolytic capacitor, it is also necessary to keep the operating temperature in different applications. The temperature range of the 604D820F200GJ7 electrolytic capacitor is -40 to +85℃, whereby the reliability of the capacitor under high temperature can be strongly guaranteed.

In sum, 604D820F200GJ7 aluminum electrolytic capacitor is highly dependable and has proven to possess long-term reliability in many different applications. Its excellent performance makes it accepted and trusted by world-wide customers.
