Tantalum Capacitors

Tantalum capacitors are one of the most stable types of capacitors available, used for a variety of applications such as providing power for integrated circuits, smoothing high frequency signals, buffering and decoupling, and filtering. They are composed of two conductive plates separated by a dielectric layer, typically made of tantalum or niobium. In the case of the T351A105K035AT, the two plates are made of tantalum and sandwiched between a piece of tantalum nitride (TaN) dielectric. This capacitor is designed for surface mounting and has a rated capacitance of 10 microfarads (μF), a rated voltage of 35 volts (V) and an operating temperature range of -55°C to +125°C.

Working Principle of T351A105K035AT

Tantalum capacitors work on the principle of electrostatic accumulation. When a voltage is applied across the plates, an electric field is created within the capacitor. This stored charge on the conductive plates is opposed by the dielectric constant, which is what produces the capacitance. This capacitance can be used to store electrical energy, just like a battery.

When the capacitor is charged, the dielectric layer increases the size of the plates. This increases the capacitance and causes the capacitor to hold more energy. The TaN layer in the T351A105K035AT helps to reduce the amount of oxide growth on the plates as well as increase the temperature capabilities of the capacitor.
