Tantalum Capacitors, especially TARS475K035 capacitors offer an extremely wide range of performance characteristics and are used in many different applications. This breakdown of the application field and the inner workings of TARS475K035 helps engineers, designers, and users fully understand what this device offers and how it leads to better electrical solutions.

Capacitor Components

Capacitors are composed of two electrical conductors that are separated by an insulating dielectric material. The conductors, commonly referred to as plates, are made of a variety of materials, such as aluminum, copper, or tantalum. In general, as the voltage applied across the capacitor increases, the dielectric constant of the material decreases. As a result, capacitors constructed with materials such as tantalum become the go-to choice for high-voltage applications. TARS475K035 capacitors are no different, providing a dielectric constant of 8.5 and a rated voltage of 25V-200V DC. Other properties associated with dielectric materials including temperature coefficients, dissipation factors, and surge limits all should be considered before implementation.

TARS475K035 Working Principle

TARS475K035 capacitors are constructed with three terminals, two of which are the end plates, while the third is an insulated element embedded between them. The two end plates act as the anode and cathode, while the insulated element functions as the dielectric material. A voltage applied across the two plates causes electrons to move across the dielectric material on the third terminal. This creates an electrostatic field, which in turn creates the capacitor’s electric charge. When a circuit is connected to the capacitor, the electrons generated on the third terminal are discharged through the circuit, producing a current.

Application Field

TARS475K035 capacitors are commonly used across a broad spectrum of electronic devices. This includes the use in amplifiers, RF filters, and other high-speed circuits. The desired characteristics of the capacitor such as voltage, temperature, and change can also determine the application. For instance, TARS475K035 capacitors are used extensively in power supply applications. This is due to the low voltage limit of the capacitor, allowing designers to reduce the output voltage of the power supply if needed. These devices offer both high resistance to thermal shock and low plastic deformation, allowing for high-temperature operation.

Another application field for TARS475K035 capacitors is motor drives and other automotive electronics. These capacitors offer lower insertion and removal forces compared to other types of capacitors, making them more suitable for the automobile applications. Furthermore, the robust construction of the device makes it resistant to shock and vibration.

In general, the wide operating temperature range, high voltage rating and low ESR make TARS475K035 capacitors a great choice for many applications. This device will continue to see implementation across a growing field of technologies.
