Working Principle:

Tantalum capacitors are made of tantalum foil, an oxidized insulator, and a conductor that acts as the other plate. The capacitor works in the same general way as other types of capacitors, by charging up and discharging. When a source of voltage is applied to the capacitor, electrons from the source are attracted to the oxide layer at the surface of the negative electrode. Due to the thin oxide layer, electrons can move through this layer and form electrical charges on the surface of the dielectric, resulting in a buildup of charge on the surface of the capacitor.

When the source is taken away, the capacitor discharges. The electrons in the negative electrode are attracted back to the conducting plate, and the charge on the surface of the dielectric dissipates over time. This process repeats each time a voltage source is applied, allowing the capacitor to store and release energy when needed.

The TAP685M035SRW capacitor is a prime example of the superior performance offered by tantalum capacitors. With its lead-free design, high-energy density and low profile, it is a perfect fit for a variety of applications requiring dependable, reliable and high-performance capacitors.
