Tantalum capacitors are one of the most widely used forms of capacitors available on the market today. In this article, we will discuss the application field and working principle of M39003/09-4066/HSD, a popular type of tantalum capacitor.

Overview

M39003/09-4066/HSD, also known as “tantalum bead-type capacitors,” are small cylindrical capacitors usually ranging from a few millimeters in length to 1 centimeter in diameter. These capacitors are made of a layered construction of conductive layers and a dielectric layer of tantalum oxide, with a metal top and bottom accordingly. These particular capacitors are available in both radial and axial leaded variations. This type of capacitor is available with capacitance values ranging from 0.1uF up to 330uF and working voltage ratings between 16-50V.

Application Fields

Tantalum bead-type capacitors such as the M39003/09-4066/HSD are commonly used in various electronic applications that require small, higher-performance capacitors like those found in computers, phones, audio systems, and other electronic devices. Because of their high stability and low losses, they are also commonly found in military and aerospace applications, and can be used for filtering and noise suppression.

Working Principle

The basic working principle of all capacitors — including the M39003/09-4066/HSD — is based on electrical charge. At a fundamental level, the capacitor acts as an electrical “storage tank” — when a voltage is applied across the capacitor terminals, electricity is stored in the capacitor’s dielectric. Then, when the voltage is removed, the stored energy is released.

In the case of the M39003/09-4066/HSD, it has a tantalum dielectric that offers good dielectric performance over a range of temperatures and frequencies. The metal top and bottom, meanwhile, provide a stable connection between the capacitor plates. As a result, the capacitor is able to store electrical energy, allowing it to perform its intended function.

Conclusion

M39003/09-4066/HSD is an excellent choice for a wide range of applications due to its high stability, low losses, and good dielectric performance over a range of temperatures and frequencies. As a result, it is commonly used in computers, phones, audio systems, and other electronic devices, as well as in military and aerospace applications. For these reasons, it is one of the most popular tantalum capacitors currently available on the market.
