Tantalum capacitors are widely used in a variety of electronic circuit applications; with the current rise of consumer electronics such as mobile phones, they have become an essential part of the current industry.M39003/03-0184H is a series of tantalum capacitors from manufacturer EPCOS which offers high reliability in its components. In this article, we will discuss the application field and working principles of M39003/03-0184H.

Tantalum Capacitor

A tantalum capacitor is a type of electrolytic capacitor, which is a passive electrical component used to store electrical energy. It consists of two electrodes, an anode and a cathode, which are separated by an electrolyte. The electrodes are generally made of tantalum metal, which is a refractory element, and is very chemically stable which provides a good corrosion resistance in the presence of acids. The extremely thin dielectric layer on the anode is usually made of tantalum pentoxide, and the electrolyte is either an aqueous solution of non-conductive, or a polymer solution. The advantage of using a tantalum capacitor is that it can provide higher capacitance values with a smaller package size compared to other types of capacitors. As a result, tantalum capacitors are generally used in a wide range of consumer electronics and products.

M39003/03-0184H

M39003/03-0184H is a series of tantalum capacitors from manufacturer EPCOS and provides high reliability and long-term stability in its components. M39003/03-0184H are available in various sizes from 1uF to 220uF, and they generally have a rated voltage of 10V, 16V, or 25V. It is a Non-polarized capacitor which means it has only one polarized lead. This type of capacitor has a wide operating temperature range and is generally used in high temperature applications as it can withstand up to 125°C. The capacitors are also resistant to moisture and provide a good tolerance to maintain stable voltage over its operating temperature range.

Application Fields

M39003/03-0184H capacitors are most commonly used in DC-DC (Direct-Coupled Electron-Coupled) convertors, as the continuous DC current supplied to the circuit easily passes through the capacitor. They are also ideal for bypassing and filtering applications, as they help reduce noise and prevent signal interference. Furthermore, they are commonly used in circuits that require power-protection, as they are not affected by load surges. M39003/03-0184H are also often used in television monitor circuits, high frequency switching circuits and oscillators.

Working Principle

The functioning of M39003/03-0184H relies upon the relationship between voltage and capacitance. When a voltage is applied across the capacitor, an electric field will form between the conductors, and this will cause electrons to flow from one conductor to the other, creating a charge across the capacitor. This charge will be maintained by the dielectric layer (tantalum pentoxide) separating the conductors. When the voltage across the capacitor is removed or reduced, the charge will slowly dissipate, allowing the capacitor to discharge and releasing the stored energy.

In conclusion, M39003/03-0184H is a series of tantalum capacitors from manufacturer EPCOS. These capacitors have a wide range of applications such as in DC-DC converters, filter and bypassing circuits, power-protection circuits, and television monitor circuits. The working principle of this capacitor relies on the basic relationship between voltage and capacitance, allowing it to store energy and quickly discharge it when the applied voltage is removed.
