Tantalum capacitors, or simply “tantalum”, are a special type of capacitor and were developed to serve certain specific applications. They are available in various sizes and have a number of advantages over standard electrolytic capacitors. This article will discuss the application and working principle of the 150D126X9060S2B tantalum capacitor.

Form Factors and Capacitance

The 150D126X9060S2B tantalum capacitor is a solid molded type with an axial lead connection. It is available in a variety of form factors, including, but not limited to, the DO-204AU, DO-214AC, and the DO-215AA-B. Capacitance values for this type of capacitor range from 0.47µF to 470µF, with a tolerance of ±10%

Operating Voltage

The operating voltage for these capacitors range from 4V to 35V. It is important to note that, despite having a rated voltage of 35V, the DC reverse voltage of this capacitor must not exceed the rated voltage in order to prevent damage.

Applications

Tantalum capacitors are most commonly used in applications where low currents and high capacitance stability are required. They are often utilized in radio-frequency and high-frequency DC-to-DC converters, DC-to-AC inverters, charge pumps, oscillators, pulse circuits, power supplies, battery-backed power supplies, and other electronic devices.

Working Principle

The working principle of a tantalum capacitor is the same as any capacitor. In short, a capacitor is an electronic device composed of two conducting plates that are separated by a dielectric medium. When an electric field is applied to the plates, electrons accumulate on one plate, resulting in a net positive charge on the other plate. This creates an electric potential that stores energy.

In the case of a tantalum capacitor, the plates are composed of a sintered anode of tantalum and a dielectric oxide layer. The dielectric oxide is composed of an insulating material such as manganese dioxide. When the capacitor is charged, the positive ions of the manganese dioxide migrate to the anode, creating a potential difference between the plates. This potential difference is what stores energy.

Conclusion

The 150D126X9060S2B tantalum capacitor is a special type of capacitor that is useful in a wide range of applications. It is available in a variety of form factors and offers good capacitance values and tolerance. The operating voltage for this capacitor is 4V to 35V and its working principle is the same as any other capacitor. As such, it is an excellent choice for a variety of applications where low currents and stability are important.
