Tantalum capacitors possess superior electrical characteristics compared to traditional capacitors, making them the preferred choice for applications in many electronic systems. The M39003/01-6358/TR is a popularly used tantalum capacitor for various applications. It has a high capacitance to size ratio, excellent high temperature operation, low and stable ESR, and long shelf life. This article will discuss the application fields and working principle of the capacitor.

Application Fields

M39003/01-6358/TR is a low-ESR, polymer-in-film tantalum capacitor that is mainly used in high-frequency and high-reliability environments. It is used in communication systems, aerospace shuttles, medical equipment, and precision instruments. It also works well in battery powered systems because of its low leakage current, low ESR, and long shelf life.

This capacitor has a high Voltage Rating of 25V, allowing it to be used in circuits where higher voltages are required. Its high capacitance to size ratio also allows it to be used in small-sized circuits. In addition, its low resistance and high frequency characteristics make it suitable for use in high-precision applications such as GPS devices, start/stop controllers, current or voltage measurement devices, vehicle navigation systems, and other automotive electronics.

Working Principle

A tantalum capacitor is an electrolytic type capacitor which consists of two electrodes made of tantalum foil, separated by a solid manganese dioxide electrolyte. The tantalum foil is used for the anode, while the manganese dioxide is used for the cathode. When a voltage is applied across the capacitor, a current passes through the electrolyte, resulting in the formation of a layer of manganese dioxide on the tantalum foil. This layer serves as a conducive material between the two electrodes and acts as a dielectric.

The amount of capacitance offered by a tantalum capacitor is determined by the ratio of the plate area to the thickness of the dielectric layer. A thicker dielectric layer results in a higher capacitance. The M39003/01-6358/TR capacitor has a higher capacitance to size ratio because of its thick dielectric layer and its compact design.

Apart from its high capacitance, the capacitor also offers high temperature operational stability and low ESR. Its low ESR ensures that the capacitor can handle relatively high current loads, resulting in better efficiency in the circuit. In addition, its low leakage current means that it can be used in battery powered systems as it does not consume much current.

Overall, the M39003/01-6358/TR tantalum capacitor is a highly advanced device that offers excellent electrical characteristics at a very small size. Its superior features make it the preferred choice in many challenging electronic applications.
