Tantalum Capacitors

Tantalum capacitors, such as the 299D106X0025CB1E3, are widely used in the electronics industry due to their high volumetric efficiency, low cost, and stability of characteristics over wide temperature range. They have found use in medical electronics, doorbells, sensor circuits, communications, aerospace, and instrumentation applications, among many other uses.

Tantalum capacitors are solid-state devices which are employed to store an electric charge. A small amount of material is sandwiched between two layers of a metal-insulator-metal (MIM) assembly, forming a capacitor when a DC voltage is applied. The materials used are a porous form of the metal tantalum, which serves as an internal electrode, and dielectric oxide layers such as manganese or niobium, which acts as dielectric. The other electronic element typically used in these capacitors is an element called a solid electrolyte, which is installed between the dielectric oxide layer and the metal-insulator-metal assembly to form the capacitor.

The use of tantalum in capacitors is advantageous due to several factors. Firstly, it has a greater dielectric constant (a measure of the voltage per unit area) than many other materials normally used in capacitors, such as aluminum or polymer. As a result, tantalum capacitors can store more charge than other types. Secondly, the low resistivity of the material means that the capacitors can better withstand temperature fluctuations without damaging the dielectric oxide layers, improving the stability of the device and allowing it to be used in higher temperature environments. Finally, tantalum capacitors typically have lower leakage currents than either aluminum or polymer capacitors, reducing the total power consumption of the device.

The 299D106X0025CB1E3 is a classic example of a tantalum capacitor in common use. This device has a capacitance of 10µF and a maximum working voltage of 25V, with a working temperature range of -55 to +125°C and a tolerance of ±20%. It can be used to store a charge for applications such as bypassing, decoupling, charge/discharge, transient and energy storage purposes. The device is relatively simple to operate, with its working principle being that of a simple electrostatic field developed across the two terminals of the device.

Tantalum capacitors are becoming increasingly popular and are now commonplace in modern electronics. In terms of their application, they can be used in a range of different scenarios where a steady charge is needed, including audio, video, and medical electronics, as well as in communications, aerospace, and instrumentation applications. The 299D106X0025CB1E3 is a typical example of a tantalum capacitor, with its high volumetric efficiency, low cost and stable characteristics making it suitable for a wide range of applications.
