Tantalum Capacitors M39003/01-7092H application field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of capacitor that uses tantalum as an oxide layer that acts as the dielectric of the capacitor. They have better performance than ceramic capacitors and are typically used within more complex electronics. The M39003/01-7092H is a special type of tantalum capacitor that is used in many applications. In this article, we will discuss the application field of the M39003/01-7092H and its working principle.

Application Field

The M39003/01-7092H is a small, cylindrical capacitor predominantly used in military and aerospace applications where its high reliability and performance are of great importance. This type of capacitor is typically used to store electrical energy, inversely reduce supply voltage fluctuations, or filter out noise. Thanks to its low ESL, ESR, and temperature coefficients, the M39003/01-7092H is also widely used in power converters and switchmode power supplies, where it functions as a storage element for inductive loads. Additionally, this type of capacitor can be used in various industrial applications, such as motor drives, factory automation equipment, and HVAC systems.

Working Principle

The M39003/01-7092H is a tantalum capacitor that utilizes a tantalum oxide dielectric. This oxide layer forms an insulating barrier between two metal plates, thus allowing it to store electrical energy. This capacitor is constructed by etching a pattern of wires onto a sheet of tantalum and then tightly rolling the sheet into a tube. This creates a unique mesh of wires that gives the capacitor its cylindrical shape.When a voltage is applied to the capacitor, electric current passes through the foil and causes electrolyte ions to attach to the oxide layer, creating a barrier. The barrier prevents the current from passing through the resistor directly, thus creating the capacitor. This process continues until the voltage applied reaches a certain point, at which point the electrolyte ions are unable to adhere to the oxide layer, and the current passes through the resistor directly.

Conclusion

The M39003/01-7092H is a special type of tantalum capacitor used in a variety of applications including military and aerospace projects. It utilizes a tantalum oxide dielectric that allows it to store electrical energy and filter out noise. Its low ESL, ESR, and temperature coefficients make it ideal for applications such as power converters, motor drives, switchmode power supplies, and HVAC systems.
