Tantalum Capacitors

Tantalum capacitors (also known as tantalum electrolytic capacitors) are a special classification of capacitors that use tantalum as the anode, which is a naturally occurring element. The tantalum anode is immersed in an electrolyte, typically an aqueous or alcoholic solution, which acts as the cathode. This creates a capacitor that is capable of storing a charge and quickly releasing it when needed.

Excessive temperature and humidity can destroy the anode, so the tight tolerance requirements of tantalum capacitors make them particularly suitable for use in military and aerospace applications. These extreme conditions would have a greater impact on the standard aluminum electrolytic capacitors.

The TACU106M002X is a electrolytic capacitor of the tantalum type, through-hole style. It is used mainly in consumer electronics and applications that require a low voltage ripple over temperature, like power supplies and stock control. It is a surface-mount tantalum capacitor of about 1µF in size. The capacitor has an operating temperature of -55 to +85 degrees Celsius and +125 to +165 degrees Celsius for soldering. Its rated voltage is 2.5V and it has 0.1 ohms initial impedance.

Using its internal anode, the TACU106M002X capacitor draws a certain amount of current from the circuit to charge up its internal storage arrangement, the dielectric layer. The dielectric layer is then sandwiched between two metal plates, the anode and the cathode. Once the dielectric layer is charged up to the reference voltage, the capacitor is ready to release its stored energy when a lower voltage is present than the reference voltage.

The current in the resistor that prevents the electric charge from flowing away from the capacitor will pass its value through the capacitor and across the gap between the anode and the cathode, enabling the electric current to flow more freely across the gap between them.

In further detail, the TACU106M002X capacitor works on the same fundamental principles as other tantalum capacitors, but its specifics differs in the following ways. Its dielectric layer is made of MnO2, its anode is made of tantalum and its cathode is made of aluminum oxide. It has a tolerance of 20%, which means that the capacitance of each capacitor can differ by up to 20% from the capacitance specified in the datasheet. Additionally, its voltage rating is a very low 2.5V, which makes it suitable for use in low-voltage circuits.

In conclusion, the TACU106M002X capacitor is an ideal choice for any type of application requiring a high-capacitance tantalum capacitor, as it is generally easier to work with compared to other types of capacitors. Its voltage rating, tolerance and capacitance are all favourable points, making the TACU106M002X a perfect choice for those looking for a reliable, low-voltage capacitor.
