Tantalum Capacitors

Tantalum capacitors, or Tantalum electrolytic capacitors, are polarized capacitors, making them essential components in a variety of electronic devices. Their name comes from the material used in their anode, which is a highly stable and durable metal: tantalum. These capacitors can vary in size and shape, but they all use the same principle of capacitance to store electrical energy.

Tantalum capacitors can be used for both DC and AC applications, and are most often used to provide short circuit protection, filtering of signals, and buffering of current. Due to their ability to store and release energy quickly, they are well suited for applications where a high power surge is needed for a brief period of time such as audio amplifiers, timers, and regulators.

293D476X9010D2TE3 application field and working principle

The 293D476X9010D2TE3 tantalum capacitor is a polarised device specifically designed for use in high-current, high-voltage applications. The device is generally used in power supply circuits and can take up to 25V of DC input. The device has a capacitance of 47 μF and is available in an SMD package.

A tantalum capacitor works by storing electrical charge between two solid metal plates called ‘plates’ and a dielectric material called ‘dielectric’ separates them. The plates are made from a conductive material such as tantalum, and the dielectric is a non-conductive material like glass, ceramic, or porcelain. The capacity or the ‘capacitance’ of the capacitor is determined by the plate area and the distance between the two plates.

When an electrical voltage is applied to the capacitor, the charge is stored on the plates and the dielectric. When the voltage is removed, the energy stored on these components will slowly dissipate. This delays the release of the energy when the voltage is removed, thus allowing the device to act as a buffer and filter. This effect can be used to filter or smooth out power supply fluctuations.

The 293D476X9010D2TE3 tantalum capacitor is a low voltage device, so it should be used in circuits where the voltages do not exceed the rated value. The device has very low leakage and is therefore ideal for high frequency circuits where the frequencies can range from kHz to tens of kHz. The device has an effective temperature range up to 125°C, and can be used in both high and low temperatures. These parameters make it well suited for use in power supply circuits.

In conclusion, the 293D476X9010D2TE3 is a tantalum capacitor specifically designed for use in high-current, high-voltage applications. The device can take up to 25V of DC input, has a capacitance of 47 μF, and is available in an SMD package. The device has low leakage and is ideal for use in power supply circuits, filtering or smoothing out power supply fluctuations.
