Tantalum Capacitors

T491A105K035ZT7280 is a series of tantalum capacitors, developed by KEMET. it is the preferred capacitor type with a wide range of applications. The combination of its high density, reliable performance, outstanding frequency performance, and other features like high temperature performance and high current carrying capacity make it popular in the area of aerospace, defense, medical, and industrial systems.

Applications

T491A105K035ZT7280 is often used for the purpose of energy storage. It is used to maintain a steady charge by storing and releasing this charge when required. This is why it is used in applications ranging from storage of electrical energy for a power supply in computer systems to standby batteries for telecommunication and data processing systems. It is also suitable for frequency-sensitive applications such as oscillators, resonators, and filters. Since tantalum capacitors have low temperature coefficients and high dielectric constants, they are typically used in fields that require reliable performance over extended temperature ranges.

Other applications include low-frequency radio transmitters, transceivers, and amplifiers. This is because the high specific capacitance of tantalum capacitors makes them the ideal choice for size-sensitive applications. The robust design of the tantalum capacitors also makes them well suited for refillable applications.

Working Principle

T491A105K035ZT7280 is an electrolytic capacitor mainly composed of two separated conductors plates. between these conductors, a dielectric material is put in that can store an electrical charge. The charge is transferred from one conductor to the other via the dielectric material as a function of the capacitance of the capacitor.

The high capacitance of tantalum capacitors is achieved by using a combination of a tantalum plate that is etched with a pattern of permanent dielectric grids to increase the surface area of the plate and a solid polymer material as the second layer. This combination is known as the volumetric capacitor principle, and it is the major reason why tantalum capacitors are ideal for applications that require high specific capacitance.

The design of this type of capacitor is resistant to vibration and shock, so it is commonly used in applications like military equipment. In addition, the low Equivalent Series Resistance (ESR) of tantalum capacitors also makes them a great choice for power supply filtering applications where low ESR is desired.
