Tantalum Capacitors

Tantalum capacitors are polarized capacitors with a tantalum oxide dielectric layer. Their most distinguishing feature is their very large capacitance for a given size. They are commonly used in applications which require a high capacitance in a limited space, such as in medical devices and in cellular phones.

150D186X9050R2TE3 Application Field

The 150D186X9050R2TE3 is a type of tantalum capacitor that is often used in automotive, telecom and industrial electronics. These capacitors are often used to store energy in high-voltage circuits, as they can tolerate up to an 85V DC rating. They are particularly useful for power conditioning and filtering, since their extremely low equivalent series resistance and inductance values enable them to provide a stable electrical field regardless of operating temperature or load.

150D186X9050R2TE3 Working Principle

Tantalum capacitors are constructed of two electrodes and a dielectric layer. The electrodes are typically constructed of tantalum foil. On one side of the electrode is a metalized layer, which acts as the cathode, and on the other is a porous layer, which provides high capacitance. The dielectric layer is constructed of tantalum oxide which, when a voltage is applied, creates an electric field between the two electrodes. This electric field accumulates charge and produces an electrical field that has the ability to store energy. When a potential difference is applied to the electrodes of the capacitor, an electrical field is created within the dielectric layer which stores energy in the form of an electrical charge. As the voltage increases, the amount of energy stored by the electrical field increases, creating a capacitance. This capacitance is then used to store electrical energy, making it suitable for power conditioning and filtering applications.

Conclusion

Tantalum capacitors such as the 150D186X9050R2TE3 provide an efficient way to store energy in high-voltage applications, since their extremely low inductance and equivalent series resistance values make them ideal for power conditioning and filtering. Thanks to their small size, they are particularly useful when space is at a premium.
