Working Principle

The T491D156M020AT tantalum capacitors are composed of a porous anode that is pressed in to a shape and encased in a metal shell. The anode mixture is made of tantalum powder and a conductive additive, usually manganese dioxide (MnO2). When a voltage is applied to the capacitor terminals, the resulting electric field allows an ionic current to pass from the anode to the cathode, creating a physical barrier between them. This barrier, known as the dielectric, is what allows the capacitor to store charge and function as a filter.

The T491D156M020AT’s architecture is highly stable and able to provide excellent electrical performance in a variety of conditions. Its low-ESR characteristic makes it ideal for applications requiring high power management, particularly in low-power environments.
