Description of the M39003/01-7225H

The M39003/01-7225H is a two-terminal, single-layer, non-polarized type of tantalum capacitor. It is a relatively low-cost component that can store a significant amount of energy and provides a very high capacitance density. It measures 4 mm * 5 mm and has an overall package height of 0.45 mm. It is available in both through-hole and surface-mount varieties. The capacitor is typically constructed using tantalum powder and other metal oxides, which are enclosed in a thin metal sheath.

Working Principle

Tantalum capacitors are electrical components that rely on an electrochemical process to store electrical energy. This process is known as the “Faraday effect” which states that when an electric field is applied to a material, a capacitance change is induced. The M39003/01-7225H works by using a solid dielectric electrolyte. This electrolyte is a combination of an electrochemical film and a tantalum oxide layer. When an electric voltage is applied to the two electrodes, an electrochemical reaction takes place, which causes the storage material to attract electrons. This forms an electric field across the dielectric material and capacitance is formed.

Application Field

The M39003/01-7225H is suitable for a variety of application fields. It can be used in power supplies, power amplifier circuits, and even medical electronics. The component is especially useful in high-frequency circuits. It is capable of operating at frequencies up to 10 MHz and has very low equivalent series resistance (ESR). This makes it ideal for use in switching power supplies and resonant circuits. Additionally, its non-polarized nature makes it suitable for circuits that utilize a large number of transistors.

Conclusion

The M39003/01-7225H is a type of tantalum capacitor that is highly versatile and suitable for a wide variety of applications. It has a high capacitance density, low equivalent series resistance, and is capable of operating at high frequencies. As a result, it is ideal for use in power supplies, power amplifier circuits, resonance circuits, and medical electronics. Understanding the working principle of the component as well as the various application fields that benefit from its use is essential for optimal performance.
