Introduction

Tantalum capacitors have been around since the early 1960s and are widely used in the industry today. The tantalum capacitor is constructed from a tungsten alloy, which is the actual dielectric material of the device. The cathode is generally aluminum, while the anode is a mixture of manganese dioxide and an electrolyte. The unique properties of the tantalum material make it an ideal choice for electronics. The term “T197A156M030AS” denotes the physical characteristics of a particular type of tantalum capacitor such as its capacitance and voltage characteristics. This article will discuss the application field and working principle of the T197A156M030AS tantalum capacitor.

Application Field

Tantalum capacitors are an integral part of many electrical and electronic applications. They are used in standard power supplies, audio amplifiers, motors, computers, telecommunications systems, aerospace systems, medical equipment, household appliances, military equipment and more. The T197A156M030AS is a special-purpose tantalum capacitor that is specifically designed for the automotive industry. In the automotive industry, these capacitors are used for triggering low-voltage relays and for voltage stabilization.

Working Principle

Tantalum capacitors work in the same way as other types of capacitors. An electric charge is stored between two conductive plates (the cathode and anode) separated by an insulator (dielectric). The characteristics of the electric charge are determined by the type of dielectric material, as well as the area of the anode and cathode plates and the distance between them.The T197A156M030AS tantalum capacitor was designed specifically for automotive applications. Its design is able to withstand shock and vibration associated with vehicles. The dielectric material is a special tungsten alloy, which has a high temperature resistance and a low dielectric power dissipation factor. The anode plate is made of a mixture of manganese dioxide and electrolyte. There are two leads for electrical connection – one for the anode and one for the cathode.

Conclusion

The T197A156M030AS is an advanced type of tantalum capacitor used in the automotive industry. Its design features a special dielectric material and anode plate, capable of withstanding shock and vibration. It is used in many applications, such as power supplies, motors, computers, telecommunications systems, aerospace systems, medical equipment, household appliances, and military equipment. Understanding the application field and working principle of the T197A156M030AS tantalum capacitor is crucial for the efficient use of these versatile devices.
