The TR3A105M025C4000 is an example of a Tantalum capacitor commonly used in these industries. It is a RoHS compliant, low profile SMD capacitor, with a working voltage of 10V DC, a capacitance of 25 µF and a working temperature of -55°C to +125°C. It has a 10% tolerance and voltage derating. The package size of the TR3A105M025C4000 is 3328 (EIA 19mm) and the height is only 2.5mm, which is very suitable for the design of miniaturized electrical circuits.

Working principle

Tantalum capacitors working principle is electrochemical and is similar to electrolytic capacitors. They consists of an anode, a cathode, and a dielectric medium. A Tantalum anode is manufactured as a sintered pellet composed of porous sintered Tantalum, a dielectric layer of oxide and an electrolyte deposit. A solid Tantalum cathode forms the plates of the capacitor. When subjected to voltage, the oxide dielectric layer creates a barrier between the anode and the cathode and creates a space charge. The oxide layer forms a leak-proof seal, eliminating the need for a casing seal which enables the capacitor to have a shielded construction.
