Tantalum capacitors are a type of electrolytic capacitor, typically made up of two tantalum metal plates with a separator made of oxide film, and an electrolyte solution providing the ionic conductivity between the plates. The M39003/01-7056/TR is a particularly popular tantalum capacitor, known for its extremely high stability and reliable performance. This article will cover the application fields and working principles of the M39003/01-7056/TR.

The M39003/01-7056/TR is a polarised bi-directional capacitor, meaning that it has an anode and a cathode. It is a surface-mount device, meaning that its terminal leads are on the top and bottom surfaces. It is also a high-temperature, low-impedance capacitor that measures 5.9 by 5.5 by 6.8 mm in size but can store up to 680µF of capacitance.

The capacitor\'s low-impedance, long-term stability, and high-temperature performance make it a valuable asset for many applications. Its properties make it particularly suited for use in automotive electronics, such as in anti-lock braking systems or airbag systems. Its low impedance also means it can handle higher-frequency switching applications within an electrical system. Furthermore, its stability makes it a great fit for embedded systems and applications where temperature fluctuation may occur.

The working principle of the M39003/01-7056/TR is based on ionic capacitance, while the capacitor\'s storage capacity is determined by the area of the tantalum oxide film. The anode of the capacitor is made up of a sintered tantalum anode, made of the metal tantalum and then processed to create a porous structure. The surface area of this sintered tantalum is then coated with an oxide film, which acts as an insulator between the two plates and provides the capacitor with its ionic capacitance.

The electrolyte in the capacitor provides the ionic path that makes up the electrical circuit. When a voltage is applied between the plates, a small portion of the oxide film across the anode will begin to break down. This creates the ions necessary for conduction and enables a capacitance bridge to form. This capacitance bridge is known as the capacitor\'s capacitance and is responsible for storing the electrical energy.

The voltage applied to the capacitor will ultimately determine the amount of capacitance stored. This makes the M39003/01-7056/TR particularly advantageous in situations where a large amount of capacitance is required in a limited space. Thus, the capacitor can be used for a wide range of applications that require a high degree of stability and dependability.

Overall, the M39003/01-7056/TR is an extremely versatile and stable capacitor that is suitable for a wide array of applications. Its unique design properties, long-term stability, and high temperature performance make it a reliable choice for automotive electronics, embedded systems, and many other demanding applications.
