T491C107M006AT application field and working principle

T491C107M006AT is an example of one of the Tantalum Capacitors. It is particular valued for its high stability, thermal resistance, and low equivalent series resistance, making it suitable for a wide variety of applications. In this article, we cover the application field, working principle, and characteristics of a T491C107M006AT.

Application Field

The T491C107M006AT is primarily used in pulse applications, where high stability and minimal impedance are required. It can also be used in power supplies, as a filter during signal processing, or in any other applications involving the need for stable capacitance.

In power supplies, the T491C107M006AT can handle higher ripple currents than conventional tantalum capacitors, which makes them a particularly attractive option for designers looking for improved power supply performance. In signal processing, the T491C107M006AT is used to filter out extraneous noise, reduce signal distortion and crosstalk, and improve signal-to-noise ratios. Finally, its low Equivalent Series Resistance (ESR) makes it the preferred choice for applications where switching spikes and strong harmonic signals must be reduced.

Working Principle

The T491C107M006AT works on the same principle as any normal capacitor – a pair of conductive electrodes with a series of insulating layers in between them. The material and construction of T491C107M006AT capacitors are different from conventional capacitors. Unlike conventional capacitors, these components are made out of tantalum – an oxide-based electrolytic material. The electrolyte is then formed using tantalum oxide, which acts as the dielectric material between the two electrodes.

T491C107M006AT capacitors are also constructed differently from traditional electrolytic capacitors. Instead of using a flat, solid electrolyte, they are constructed using a Honeycomb Core construction. This construction involves a series of alternative conductive and insulating layers, which represent the positive and negative poles of the capacitor. The number of layers depends on the capacitance needed and the voltage of the application.

This combination of construction design and materials results in high stability and low losses. The T491C107M006AT is highly resistant to thermal shocks, as well as high frequencies, making it a preferred choice for any applications dealing with such conditions.

Characteristics of the T491C107M006AT

The T491C107M006AT has a few unique characteristics that make it a preferred choice over traditional electrolytic capacitors. These characteristics include: high stability, low equivalent series resistance (ESR), minimal impedance, and a high discharge rate.

The T491C107M006AT offers high stability, with a capacitance change of less than 5% at -55°C to +125°C and a maximum capacitance change of 13.5% over a -55°C to +125°C temperature range. This allows designers to be sure of their product\'s performance even in extreme temperatures. It also has a low equivalent series resistance (ESR) of only 0.6 ohms, which allows for more efficient power transfer and higher current handling.

The T491C107M006AT also offers minimal impedance, due to its Honeycomb Core construction. This minimizes any unwanted losses in the capacitor. Finally, the T491C107M006AT also offers a high discharge rate, thanks to its low ESR. This allows for faster and more efficient energy absorption and discharge, making the capacitors a good choice for applications involving fast transients.

In conclusion, the T491C107M006AT is a unique example of a Tantalum Capacitor, with its high stability, low ESR, and high discharge rate making it an attractive choice for designers looking for improved performance. Its Honeycomb Core construction, combined with its materials, allows it to meet a wide variety of application requirements.
