Tantalum capacitors, despite their limited amount of applications, are still useful components and are used in a number of circuits. Such as the TPSD477K006R0100 capacitor. This particular capacitor’s application field and working principle should be well understood by professionals and hobbyists who are looking to make use of them.

Firstly, the TPSD477K006R0100 Capacitor is used for DC-DC power supplies and power electronics applications, as well as audio filtering or snubbing applications. This capacitor is also utilised for embedded power supplies and are also used in electronic equipment as well as timing and level shifting circuits.

The TPSD477K006R0100 may have a small size, 2.5 x 10mm; however, the device is highly reliable and provides long term stability. This is in thanks to its solid-tantalum construction with SMP or SM technologies. Furthermore, their qualities of low ESR, robustness and extended temperature range makes them a viable choice for designs that require stability and performance.

In addition, these capacitors arrive with a higher capacitance than usual devices, allowing them to also be used in digital circuits. All of which being said, the TPSD477K006R0100 Capacitor still has it’s limitations and is not suitable for high frequency applications.

Moving onto the working principle of the capacitor, the TPSD477K006R0100 is a polarised capacitor, meaning that the electrical current flows in only one direction, allowing for a greater charge to store for a given voltage. The dual anode technique utilised also separates the cathode capacitance and the anode’s capacitance, allowing for a greater capacitance whilst reducing power dissipation.

This capacitor is a tantalum capacitor and have an anode that consists of a porous sintered tantalum material. A layer of oxide lines the anode, which act as a dielectric and allows the capacitor to have it’s voltage rating (10VDC) and working frequency (1kHz).

The capacitor’s double-anode design works to separate the cathode and anode capacitance, as one anode becomes floating whilst the other is connected to the casing. A cathode tin-plated at each contact of the two anodes is then activated and is used to exchange the electrons to the oxide layer. This exchange is used to create differing voltage levels along the oxide layer which allows the capacitor to form a capacitive path and block the direct current. Thus allowing for charge to be stored and for a voltage drop to occur at the anode.

The above explains the structure and working principle of the TPSD477K006R0100 Capacitor. This particular device is a small and reliable component that, when used correctly, is perfect for a number of applications in the power electronics and embedded power supply fields. It is a valuable device and should be better understood by hobbyists and professionals alike.
