Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor which use tantalum as its anode material. They are mostly preferred due to their low cost, small size, and high capacitance. Though they are not as efficient as other types of capacitors, they offer a combination of advantages which make them suitable for many applications.

M39003/01-2261/TR Application Field and Working Principle

The M39003/01-2261/TR application field is typically used in avionics, military, medical, automotive, consumer, telecommunications, and other electronic products. The major advantage of this device is its low power consumption, high reliability, and long working life. This device works on the principle of a solid electrolyte, which provides a stable capacitance, regardless of temperature changes. The working principle of the capacitor is that, when a voltage is applied across two electrodes, charges on those electrodes are attracted, making the capacitor charged. As long as the electric field created remains, the capacitor will maintain its charge.

The M39003/01-2261/TR application field utilises the phenomenon of double layers of stored charges between two electrodes. The double layer of charges can be referred to as electrical dipole and it is generated for the presence of the direct current in electrolytes. When current passes through the electrolyte, there is an electric field in the electrolyte which produces the layers of dipoles.

The double layers of charges can be treated as a capacitor. The functions of the double layer are to accumulate capacitance between two electrodes, to filter any fluctuations or radio frequency interferences, to reduce ringing effect and also to reduce distortion and EMI from the DC voltage. The dielectric strength of Z5U (M39003/01-2261/TR) varies from 200 to 400 volts.

In general, tantalum capacitors provide many advantages over their counterparts, including high capacitance values in small volume, high reliability, long service life, quick current flow, and low self-discharge rate. They are also ideal for a variety of power applications, such as the M39003/01-2261/TR application field, where the current flow needs to be high but the size of the device needs to be kept small. In addition, these capacitors are ideal for applications that require very low ESR values, as the dielectric used is very stable, and does not deteriorate with extreme temperatures.

Tantalum capacitors are also highly resistant to corrosion and vibration, making them ideal for use in extreme environments such as military and aerospace applications. Over the years, tantalum capacitors have been used in many applications, such as medical imaging, telecommunications, automotive, and other consumer, industrial, and commercial applications.
