Tantalum Capacitors: M39003/01-5166H Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytics, are polarized electrolytic capacitors consisting of tantalum pentoxide dielectric with an anode made of sintered tantalum. Tantalum capacitors are widely used in electronic circuits due to their relatively small size, high capacitance per unit size, and stability at high temperatures. The M39003/01-5166H is a tantalum capacitor specifically designed for military and aerospace applications. This article is an analysis of the application fields and working principles of the M39003/01-5166H tantalum capacitor.

Application Fields

The M39003/01-5166H is a high-performance, hermetically sealed, surface-mount capacitor designed for operation in extreme environment conditions, such as high temperature, shock, vibration, and humidity. It is typically used for filtering and bypass applications in military and aerospace applications. The capacitor features an anode made of sintered tantalum, a hard dielectric material with a very high dielectric constant, and an electrolyte of manganese dioxide, which provides a reliable long-term energy storage capability.The M39003/01-5166H is also widely used in other industries, such as automotive, communications, and consumer electronics. It provides power supply filtering for electronic devices with low equivalent series resistance, very low temperature coefficient, and excellent frequency response. By forming a barrier between different components, the capacitor serves as a power buffer. In automotive applications, it is commonly used as a bypass capacitor that helps reduce power supply noise.

Working Principle

The M39003/01-5166H operates on the principle of electrostatics. When current flows through a capacitor, electric charge accumulates on opposite plates, generating a static electric field between them. This static electric field causes the capacitor to store energy, which can then be used for various applications. The amount of charge stored depends on the capacitance of the device, which is determined by the size and type of dielectric material used. The M39003/01-5166H uses an anode made of sintered tantalum, one of the highest dielectric constants. Combined with its electrolyte of manganese dioxide, the capacitor is able to provide a very high capacitance with low equivalent series resistance and low temperature coefficient. This provides it with excellent energy storage and frequency response capabilities, making it ideal for applications in military and aerospace.

Conclusion

The M39003/01-5166H tantalum capacitor is designed for operation in extreme environment conditions, such as high temperatures, humidity, shock, and vibration. It offers excellent filtering and bypass capabilities due to its high dielectric constant and electrolyte. As a result, it is commonly used in military and aerospace applications, as well as automotive, communications, and consumer electronics. The device operates on the principle of electrostatics, using anode of sintered tantalum and an electrolyte of manganese dioxide to provide very high capacitance with low equivalent series resistance and low temperature coefficient.
