It has a wide range of applications, especially in digital power supplies and clock signal generation. Its dielectric material is built for a wide range of operating temperatures, allowing it to be used in various types of demanding designs.

The M39003/01-7248H can also be used in contactless battery charging systems, due to its extremely low leakage current and low voltage drop. It is also used in high-power circuits, such as power supply switching circuits. This capacitor can also be used for signal bypassing and frequency compensation.

Working Principle

The M39003/01-7248H is a three-terminal, chip-based tantalum capacitor with a sintered anode and a dielectric layer of tantalum pentoxide (Ta2O5). The anode is composed of a porous anode body and a current-collecting electrode. The cathode is a solid, sintered, metal plate bonded to the back of the anode. The capacitor works on the principle of storing the energy between these two plates.

When a voltage is applied across the two plates, an electrostatic field develops between the two plates. This field stores charge on the anode and results in a capacitance proportional to the surface area of the anode and the permittivity of the dielectric material. The capacitance of the capacitor is determined by the area of the anode, the thickness of the dielectric layer, and the permittivity of the dielectric material.

In addition, this capacitor has a very low leakage current due to the quality of the dielectric layer. The leakage current is proportional to the thickness of the dielectric layer at a certain temperature. The smaller the leakage current, the better the quality of the capacitor.
