Tantalum Capacitors

Tantalum capacitors make use of the dielectric properties of tantalum to store electrical energy and to serve as electrical components in a variety of electronic applications. The most common type of tantalum capacitor is the solid-electrolyte tantalum capacitor and the M39003/01-6087/HSD stands for a series of them. This article will discuss the application field and working principle of the M39003/01-6087/HSD tantalum capacitors.

Application Field

Solid electrolyte tantalum capacitors of the M39003/01-6087/HSD series are designed to be used in a variety of extremely sensitive and critical applications in advanced electronic equipment, where reliability and electro-mechanical stability is the most important factor. These capacitors are suitable for applications such as pacemakers, medical devices, airborne systems, missiles, databus designs, avionics, and space systems.

Working Principle

The working principle of M39003/01-6087/HSD tantalum capacitors is based on the capability of the tantalum material to store electrical energy. The capacitor is constructed of two electrodes with a layer of tantalum oxide between them - the dielectric material. When a voltage is applied to the capacitor, the single layer of tantalum oxide acts as an insulating material between the two electrodes, allowing it to store a certain amount of energy.The anode of the capacitor is constructed out of tantalum powder that is sintered with a highly purified manganese dioxide. The sintering process and the inclusion of the manganese dioxide gives the anode a porous structure that can hold an electrolyte, usually in the form of a liquid.The cathode of the capacitor is electrically connected to the anode, and to the external circuit, via a wire. This cathode is generally made of an electrically conducting material such as aluminum or copper.When the capacitor is connected to an external circuit, current flows from the anode through the electrolyte and then to the cathode. The ions of the electrolyte re-arrange themselves under the influence of the applied voltage and thus producing a storage plate for electrostatic energy charge.When the capacitor is disconnected from the external circuit, the stored charge remains and provides a low equivalent series resistance (ESR). This feature makes the M39003/01-6087/HSD tantalum capacitors ideal for use in pulse application and high frequency circuits.In summary, the M39003/01-6087/HSD series of tantalum capacitors make use of the dielectric properties of tantalum to store electrical energy in an efficient manner. They are designed for use in highly sensitive and critical applications where reliability is of great importance. The highly efficient low ESR makes them ideal for use in pulse and high frequency circuits.
