Tantalum Capacitors

Tantalum capacitors are electronic components that offer a combination of high capacitance and low equivalent series resistance. They can be manufactured in various physical sizes and capacitance values, allowing designers to choose the exact density and size required, thereby eliminating any unnecessary bulk.

These capacitors are widely used in applications where stable performance over a wide temperature range is required, such as in automotive, military and aerospace applications. As such, they are specified accordingly, with the most widely used type being the 150D474X0100A2B.

Application Field

The 150D474X0100A2B is a glass-sealed, surface mount, high-voltage tantalum capacitors specifically designed for high-temperature and harsh environment applications in automotive, military and aerospace applications. It has a voltage rating of 4 VDC, a capacitance range of 10 uF to 220 uF, and a temperature rating of -55°C to +135°C.

The 150D474X0100A2B can also be used in a wide range of other applications, including medical, industrial, and consumer electronics, as well as in instrumentation, sensing and other computer systems.

Working Principle

The primary working principle of the 150D474X0100A2B, like most tantalum capacitors, is based on the use of a tantalum pentoxide dielectric layer. This layer is sandwiched between two metal plates, with an anode on one side and a cathode on the other. When a voltage is applied to the device, charges accumulate on the dielectric layer and create an electric field. This electric field stores energy in the form of an electric potential between the two metal plates.

The charge stored in the capacitor can be discharged by connecting the positive and negative terminals of the capacitor to the negative and positive terminals of a voltage supply. This will result in a current flow capable of powering various circuitry. The amount of charge stored in the capacitor will depend on the size of the capacitor, the material used and the voltage applied.

Tantalum capacitors feature the advantage of being able to store energy at very high densities, making them ideal for high power applications. They also feature very low equivalent series resistance (ESR), which allows them to deliver high current pulses with a very small power dissipation.

The 150D474X0100A2B represents a major advancement in tantalum capacitor technology, as this particular type is designed for applications with extreme environmental conditions, such as those found in automotive, military and aerospace systems.
