Tantalum Capacitors

Tantalum capacitors, sometimes known as "ta-caps" provide a great deal of energy density. They are printed circuit board components that are comprised of a small piece of tantalum metal that is coated with an oxide material and then hermetically sealed in an epoxy case. The tantalum capacitors are then connected to external components using one or two metallic leads.

The capacitors are strongly reactive to both incoming and outgoing electrical signals. This allows them to act as an interface between electronic components. The material used for the coating makes them suitable for applications that require high temperature operation. This is because the high tolerance level of the material makes them capable of producing good results even in high temperature environments.

199D156X0020D2B1 Application Field and Working Principle

The 199D156X0020D2B1 device is a tantalum capacitor designed for use in high-power electronics projects. It has a capacitance of 156 micro-Farads at 50 volts, and it is rated to both -40 and +85 degree Celsius temperatures. Its ESR (equivalent series resistance) rating is 1.2 ohms at 100kHz.

The device works by initially charging up with an incoming electrical signal and then discharging the stored electrical energy back into the circuit when an adequate output voltage is reached. An important part of the working principle is the chemical nature of the capacitor. The oxide coating on the tantalum plate sets up an electronic barrier between the charge and the discharging plates. This barrier sees the voltage of the incoming signal, and it ramps up until the barrier is reduced to a point where the output voltage is achieved. At this point the capacitor has reached its full charge and starts to discharge.

An important factor that has to be taken into account is the power rating of the capacitor. This rating is determined by the amount of energy stored in the capacitor. The higher the capacitor\'s power rating, the higher its max output electrical energy will be.

The capacitors are also rated according to their temperature tolerance. This shows the minimum and maximum temperature ranges that they are designed to work in. A capacitor\'s temperature rating shows how much heat they can withstand before their performance starts to suffer.

As capacitors are used to store electrical energy, they must be chosen with care. Although the 199D156X0020D2B1 device is the right choice for a specific application, other tantalum capacitors may need to be considered if the required specifications are different. It is always best to double-check the device\'s specifications to ensure the highest level of safety when undertaking any electronics projects.
