Tantalum Capacitors: 152D107X9020R2B Application Field and Working Principle

Tantalum capacitors, also known as electrolytic capacitors, are widely used in electronics due to their unique physical and electrical properties. The use of tantalum in capacitors is especially advantageous due to its high efficiency and relative economies of scale. In particular, the 152D107X9020R2B is one of the most popular sub-series of the tantalum capacitor family, thanks to its versatility and efficient response.The key characteristics of the 152D107X9020R2B are its relatively high voltage rating (up to 20 Volts) as well as its very low impedance and ESR. This makes it ideal for use in applications such as high voltage ripple protection circuits, power supply decoupling, switching power supplies, as well as high-speed motor and signal processing applications. The 152D107X9020R2B also has excellent temperature stability and can operate in temperatures ranging from -55 Celsius to 125 Celsius.The working principle of a 152D107X9020R2B is based on the volumetric capacitance of charged particles. Inside the capacitor, a thin layer of tantalum powder is deposited onto two separate electrodes. The two plates act as an electrochemical capacitor, storing charge within this charged volume. Different capacitors have different capacitance values, depending on the amount of charge stored within them.In addition, the 152D107X9020R2B also has copper connections between the two plates. These copper connections allow an electrical current to flow across the plates, amping up the capacitor’s capacitance. This allows for the greater storage of charge, resulting in an increased amount of electricity Q. The 152D107X9020R2B series also utilizes a solid anode; this unique feature is designed to help maintain a stable capacitance even when exposed to higher temperatures. The anode and cathode will be connected to two steel plates, also known as ‘pole caps’, for mounting the capacitor securely. When the capacitor is subject to an alternating electric field, the charges stored in the capacitor will move in relation to the electric field. The current generated by the charge change causes an electric field which then causes an additional flow of current. This process is known as ‘electrolysis’ and allows for the capacitor’s dielectric to serve as an insulator when current is flowing through it.Overall, the 152D107X9020R2B series capacitor has a wide range of applications. It is extensively used in the computer and automotive industry. Its broad range of features make it an ideal choice for high speed circuits and a great solution for power component decoupling and ripple control. Thanks to its low internal impedance and ESR, as well as its temperature stability and wide voltage rating, the 152D107X9020R2B series are one of the most versatile and popular sub-segments of the tantalum capacitor family.
