Tantalum capacitors are a type of capacitors which consists of tantalum powder pressed into a “pellet”, and which is then wrapped with an oxide film. The typical oxide films used are tantalum pentoxide (Ta2O5), niobium pentoxide (Nb2O5) and tantalum niobium pentoxide (TaNb2O5). They have the advantage of possessing a low ESR, high capacitance, a wide temperature range and excellent linearity. The specific model T491D106K035ZT7027 belongs to the same family of capacitors.

This type of capacitor finds application in automotive, aerospace, military and consumer goods. Its low ESR parameters make it ideal for high current filtering applications, power supply management, and signal or oscillator noise attenuation as typical examples. Its design also allows it to support several scenarios, from high-end applications in the military and automotive sectors, to other markets, such as consumer electronics, medical, and industrial applications.

The working principle of this tantalum capacitor is based on the fact that when the pellet is charged with an electrical current, it forms a dielectric layer of oxide. This dielectric layer then acts as an insulator, preventing the flow of electric current through the device. This helps to control the charge of a capacitor at a particular voltage. As the electrical current increases its impedance decreases, and there is a consequent increase in charge of the capacitor, which is used to store potential energy.

In addition, the tantalum material can accept voltages up to 30 volts and temperatures up to 130°C, making it suitable for most applications. Also, due to its higher stability when compared against other types of capacitors, it performs better in temperature-dependent applications, such as radio frequency and shock-momentum applications.

The T491D106K035ZT7027 tantalum capacitors offer low ESR, tan delta and a wide temperature range that makes them suitable for a variety of applications across military, automotive and consumer markets. Their high reliability and performance enabled by this type of capacitor, along with their low cost, makes them a preferred choice over other types. In conclusion, these capacitors are great for a wide range of high current, low voltage applications and can be utilized across a number of industries.
