Tantalum capacitors are a unique class of electrolytic device with many important characteristics. The TAP155M025GSB is a tantalum capacitor designed specifically for a range of applications in both civilian and military electronics. The main functions of a TAP155M025GSB are to store and release energy in a reusable form. In this article, we will discuss the general application field and working principle of this tantalum capacitor.

Application Field

The TAP155M025GSB has a wide range of applications, including automobile, communications, power supplies, and military electronics. It is particularly well-suited to use in automotive applications where shocks, vibration, and temperature extremes are common. In military electronics, the TAP155M025GSB is often employed in radiofrequency systems, radar systems, and electronic warfare systems. Its high capacitance, small size, and low cost make it an ideal replacement for too bulky and expensive electrolytic capacitors.

Working Principle

The TAP155M025GSB is a polarized capacitor that consists of a tantalum wire-wound anode and a metal oxide film cathode. When the two electrodes are connected to a voltage source, a charge builds up on the anode and a depletion region is created in the metal oxide film. This depletion region allows electrons to flow freely between the anode and the cathode along a newly established electrical field. The amount of charge that can be stored in this device depends on its capacitance, which is determined by the area of the anode and cathode, the thickness of the metal oxide film, and the dielectric strength of the material.

The TAP155M025GSB has a capacitance of 15.5 microfarads, a voltage rating of 25 volts, and a voltage-temperature coefficient of 200 ppm/°C. It utilizes an electrolytic dielectric which has a very low tolerance for chemical contamination. As a result, it requires meticulous handling and maintenance. The device is also known to have a relatively high self-discharge rate, meaning it will lose its charge quickly when left unconnected to a power source.

Conclusion

The TAP155M025GSB is a tantalum capacitor with a wide range of applications, including automotive, communications, power supplies, and military electronics. The device features a wire-wound anode and a metal oxide film cathode, and has a capacitance of 15.5 microfarads, a voltage rating of 25 volts, and a voltage-temperature coefficient of 200 ppm/°C. It has low tolerance for chemical contamination, and relatively high self-discharge rate. With its small size, low cost, and high energy storage capabilities, the TAP155M025GSB is an ideal replacement for too bulky and expensive electrolytic capacitors.
