The working principle of T491R105M020AT can be explained by Sandrock’s 3-in-1, which stands for the interplay of electric capacity, electrical resistance and thermal reaction. Electrical capacity is often referred to as capacitance, and is the resource of storing electrical energy. Electrical resistance is a measure of the introduction of resistive elements to the physical body, and this parameter allows users to modify the current and voltage. Lastly, thermal reaction relates to the heat produced by energy consumption, which must be properly dissipated in order to help maintain the capacitance.

T491R105M020AT is the perfect solution for pulse current filtering, energy storage, oscillation stabilization and other applications requiring high stability through-hole tantalum capacitors with high temperature rating. It is a reliable, cost effective component that has extremely low ESR and a high ripple current allowing it to be used in numerous applications.

In short, T491R105M020AT is an ideal choice for high stability and high ripple current applications due to its high capacitance density, low ESR rate, high temperature rating and excellent thermal reaction. With its extremely low ESR, high temperature rating and comfortable DC bias, it can be used for numerous application field such as energy storage, pulse current bypassing, filter and stabilization.
