Tantalum capacitors are components used to store electrical energy in a variety of electronic devices and products. Developed in the early 1950s, they have since become the trusted choice for engineers due to their extremely small size and their high dielectric strength in comparison to other types of capacitors. The 293D686X9020E2TE3 is a type of tantalum capacitor that is particularly suited for use in high-performance analog applications. This article will examine the application field and working principle of the 293D686X9020E2TE3.

Application Field

The 293D686X9020E2TE3 tantalum capacitor is designed for use in demanding analog circuits, particularly those operating at radio frequencies or applied voltages above 75V. It is suitable for applications like pulse supply filtering, waveform shaping and lossy-inductive bypassing. This device also has considerable thermal resistance and is capable of high frequency operation which makes it ideal for active modulation, demodulation and control circuits.

Furthermore, it is also an excellent component choice for RF transmitter/receiver circuits due to its inherent low parasitics and minimal ESR which make it less prone to crosstalk and noise-related interference. Its excellent stability and high-power dissipation capabilities make it a great choice for high-speed, high-precision motor drives, switching power supplies and current regulators.

Working Principle

Tantalum capacitors are polarized, meaning that they have a positive and a negative terminal. This means that the device will not always dissipate the same amount of power when exposed to the same voltage, which makes it possible for it to act as either a filter or a signal amplifier. As such, the 293D686X9020E2TE3 can be used to filter out high frequencies and converting them into low-frequencies signals. Additionally, the capacitor can be used to amplify signals and to reduce noise. The way it accomplishes these tasks is by using a dielectric material that acts as an insulator to isolate two electrodes.

Because of the dielectric material, the current needs to be applied with a positive and a negative charge in order for the capacitor to achieve maximum capacitance. This is referred to as the "polarization voltage" or the "bias voltage." When the capacitor is exposed to the correct voltage, it will allow current to flow and the stored energy is then released into the circuit as an electric current or a voltage change depending on the nature of the application.

The 293D686X9020E2TE3 is a surface mount device, meaning that it is based on the latest micro-electronics engineering technology, and takes up minimal space on the printed circuit board. As such, it is the ideal choice for space constrained applications.

Conclusion

The 293D686X9020E2TE3 is a specialized type of tantalum capacitor which is exceptionally well-suited for use in analog circuits. Ideal applications include pulse supply filtering, RF transmitter/receiver circuits, waveform shaping and motor drives. This device is also capable of amplifying and reducing noise, as well as high frequency operation, due to its built-in dielectric material. Additionally, the surface mount technology used with this capacitor allows for its installation on cramped, space-restricted circuit boards.
