Tantalum Capacitors

Tantalum capacitors are electrolytic capacitors that use tantalum for the anode material in their construction. The production of tantalum capacitors, although different than ceramic capacitors, is still governed by the same fundamental principles of capacitor construction. Typically, the tantalum capacitors are constructed of a tantalum anode material, an insulation medium made of proprietary dielectric material, and an external cathode material comprising an electrolytic external cathode material and a layer of printed insulation (usually rated for a voltage of 10-16 volts).

The 109D227X9008F2 is a tantalum capacitor and the application field for this product is digital, analog, and low-power VRMs (voltage regulator modules). This capacitor is a long life type that has a surge voltage of 16V and offers low ESR performance which is ideal for high current applications. The main working principle of the 109D227X9008F2 is the storage of energy within the anode-cathode gap. When a voltage is applied the electrons flow from the anode to the cathode through the dielectric insulation. This creates a positive charge on the anode and an equal but opposite negative charge on the cathode. As a result, the capacitor will store a certain amount of charge and provide the necessary current to power the VRMs.

The advantages of 109D227X9008F2 tantalum capacitor include low ESR performance, high surge voltage, long life operation, and its ability to provide efficient power transfer. The disadvantages include a higher cost than other types of capacitors, susceptibility to reverse bias, and their susceptibility to thermal runaway (which can lead to an increase in capacitance).

Overall, the 109D227X9008F2 tantalum capacitor is an excellent choice for applications that require low ESR performance and a long life of operation. Not only does it have a higher surge voltage than other types of capacitors, it is also effective at providing the current needed to run digital, analog, and low-power VRMs. Despite its relatively higher cost, it is still widely used in a variety of applications.
