Tantalum Capacitors

Tantalum capacitors are a type of capacitors that consist of tantalum metal and a metal oxide as the storage medium. For many years, tantalum capacitors have been used in a wide range of applications, such as telecommunications, automotive, computer and other electronics. TAP474K035SRW is one of the volumetric series of capacitors offered by Vishay, one of the largest manufacturers of capacitors.

Application Field of TAP474K035SRW

TAP474K035SRW is a leakage current-limited surface mount tantalum chip capacitor designed for high temperature, high current applications. It has a robust construction that can withstand temperature changes and high vibration conditions, making it an ideal choice for military applications such as missile guidance, aviation and military communication systems, and automotive systems.

This capacitor is also suitable for low voltage commercial systems, like cell phones, Digital Video Broadcast (DVB) receivers, and wireless communication systems. In addition, it is used in areas where reliability and environmental harshness are important. Such applications include medical, automotive and industrial electronic products.

Working Principle of TAP474K035SRW

TAP474K035SRW tantalum capacitors use the principle of electric energy storage. When an electric field is applied across two metallic surfaces, electric charge is separated and stored. The electric energy stored in the capped material is directly proportional to the area of the capacitor and the electric field across it. The charge density in a capacitor is greater at higher temperature, which helps to minimize the temperature coefficient.

The amount of charge stored in the capacitor is controlled by the amount of dielectric material used between the two metallic areas. In tantalum capacitors, tantalum pentoxide is used as the dielectric material which provides high dielectric strength, low leakage current and good temperature stability.

TAP474K035SRW is also a bipolar capacitor, which means it can store both a positive and a negative charge. When a positive voltage is applied to one plate, the capacitors will store this electrical energy until the supply of the electric field is removed. Bipolar capacitors are mostly used for storing energy to supply the full-wave rectified power for applications such as audio filtering and power factor correction circuits.

Tantalum capacitors offer longer life, higher stability and greater reliability than other types of capacitors. They are also sensitive to electrical pulses, making them ideal for applications such as signal strain gauges, integrated circuit timing devices, signal filtering and power regulation.

In conclusion, TAP474K035SRW is a type of leakage current-limited surface mount tantalum capacitor designed for high-temperature, high-current applications worldwide. It has a robust construction that can withstand temperature changes and high vibration conditions, which makes it ideal for many applications including automotive, military, medical and industrial applications. It is sensitive to electrical pulses, which make it suitable for a wide range of signal filtering, strain gauging and power regulation applications.
