Tantalum Capacitors: TAJW226M010RNJ Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitor, which is based on the dry electrical double layer capacitor. They use tantalum metal for the anode component and once combined with a dielectric material form the capacitor. Due to their design and materials used, Ta capacitors have good high frequency characteristics and high energy density, as well as a wide variety of temperature ranges.

The TAJW226M010RNJ and its Application Field

The TAJW226M010RNJ is an electrolytic capacitor manufactured by Kemet Electronics Corporation. This particular model is an Niobium Oxide (NbO) based surface mount tantalum capacitor with a rated capacitance of 2.2 microfarads, a voltage rating of 10V, and a temperature range from -55°C to 150°C. The TAJW226M010RNJ is widely used in the high frequency electronics market for its high frequency characteristics, good reliability and small size. It is commonly used in applications such as power converters, DC to DC converters and switch mode power supplies, as well as in telecommunications and automotive electronics.

Working Principle of the TAJW226M010RNJ

The TAJW226M010RNJ operates on the principle of an electric double layer capacitor (EDLC) combined with tantalum metal. The capacitor has a sintered tantalum anode and the NbO ceramic dielectric material is used as a separator. This separation produces a negatively charged anode and a positively charged dielectric material, which a form an electric double layer around the anode. This double layer produces a high capacitance of up to 2.2 microfarads. The NbO ceramic dielectric material provides a high insulation breakdown voltage of up to 160V, which allows the capacitor to operate at a high voltage.

When the capacitor is in use, the electric current passing through the capacitor induces a voltage in the anode and an opposing voltage in the dielectric. As the voltage increases, the anode and dielectric layers become increasingly charged, resulting in an increase in capacitance. The TAJW226M010RNJ is equipped with an internal impregnation which allows it to withstand mechanical shocks, vibration, and temperature extremes without affecting the performance of the capacitor. This impregnation also works to increase the capacitor’s lifetime and reduce its risk of failure.

Conclusion

The TAJW226M010RNJ is a reliable and high-performance electrolytic capacitor that can be used in a wide range of electronic applications. Its high capacitance, high voltage and high temperature capabilities make it ideal for high frequency electronics applications. Its NbO ceramic dielectric provides excellent high frequency characteristics, which are further enhanced by its internal impregnation. This makes it ideal for power conversion, DC to DC converters, switch mode power supplies, telecommunications and automotive electronics.
