Tantalum capacitors are widely used in electronic circuit design, and the M39003/01-2357H is an example of a tantalum bipolar capacitor with a wide range of applications. This article will discuss the application field of the M39003/01-2357H, as well as its working principle.

Overview

Tantalum capacitors are constructed from a tantalum anode and a cathode made of an oxide dielectric. They offer high vibration resistance, higher temperature coefficients, and many other performance benefits which make them very popular for use in modern electronic circuit designs. The M39003/01-2357H is a bipolar tantalum capacitor with a maximum capacitance of 680μF.

Application

Tantalum capacitors are typically used for audio applications, as they have good frequency response, low distortion, and excellent noise rejection. The M39003/01-2357H is a popular choice for medical and consumer electronics, as it offers a high ripple current at a low ESR. Additionally, the capacitor’s low profile and wide temperature range make it suitable for use in difficult to cool applications.

Working Principle

The working principle of a tantalum capacitor is the same as that of other dielectric capacitors. When a bias voltage is applied to the two terminals of the tantalum capacitor, free electrons pass through the oxide dielectric material and create an electric field, which then creates a depletion region between the anode and cathode. This depletion region stores the charge, creating the capacitance. The amount of charge stored is determined by the voltage applied to the device, as well as the area of the depletion region.

Features

The M39003/01-2357H offers some technologic features that make it desirable for many applications. It’s a very low ESR electrolytic capacitor, with a minimum of 0.33Ω. Additionally, it’s designed to withstand higher temperatures, up to 125°C. This makes the M39003/01-2357H an ideal choice for use in power supply, temperature sensing, and consumer electronics applications.

Conclusion

The M39003/01-2357H is an example of a tantalum bipolar capacitor with a wide range of applications. It has a low ESR and is capable of withstanding higher temperatures, making it ideal for use in audio applications, medical devices, and many other consumer electronics. The M39003/01-2357H operates on the same principles as other dielectric capacitors, using a biased electric field to create a depletion region which stores charge and creates capacitance.
