This solid-state electronic component is most often used in high-end consumer electronics, audio/video applications, and industrial electronics. This article will discuss the application fields and working principles of the M39003/03-4027/HSD.

Application Fields

The M39003/03-4027/HSD capacitors are predominantly used in high-end consumer electronics, such as high-end TVs and home theater systems. This capacitor type is also often used in sensitive audio/video equipment, including amplifiers, subwoofers, and audio processing components. In addition, the capacitors can be used in communication systems, including cellular phones, GPS systems and satellite receivers. Additionally, it can be used in industrial electronics, medical devices, power converters, and high-reliability applications requiring a wide operating temperature range.

Working Principle

Tantalum capacitors, such as the M39003/03-4027/HSD, are made up of two metal plates, separated by a dielectric layer. The two plates are joined to the capacitor\'s terminals and form the capacitor\'s main components. When the capacitor is connected to a voltage source, current begins to flow and charges the plates. This causes the plates to accumulate a certain amount of electrical energy, resulting in a voltage in the electrostatic field. As current continues to flow, a dielectric material, usually a thin layer of tantalum oxide, provides direct contact between the two plates. This layer of oxide prevents any short circuits, and ensures that the stored energy is not drained or lost.

The dielectric, in combination with the capacitor\'s electrodes, is responsible for its high-frequency performance and low self-resonance. The dielectric material determines the amount of capacitance value, which is measured in farads. The M39003/03-4027/HSD has a capacitance value of 47 µF and an operating temperature range of -55 to +125 °C.

In addition to the dielectric material, the M39003/03-4027/HSD is also made up of other components, such as electrodes and a Y5V ceramic body. These additional components offer optimizations in terms of size, stability, and other performance-related factors.
