Tantalum Capacitors

Application Field and Working Principle of 199D106X0010B6V1

Tantalum capacitors are highly surface mountable capacitors traditionally used on most embedded microelectronics designs today. The 179D106X0010B6V1 is a surface mountable tantalum capacitor with an Electrolytic Nickel Plastics (ENP) surface finish. The capacitor has an operating temperature range of -55°C to +85°C, and its typical capacitance ranges from 12 μF to 100 μF. Unlike other surface mountable capacitors like ceramic capacitors, tantalum capacitors offer higher working voltages and better high-frequency performance. The 179D106X0010B6V1 tantalum capacitor is commonly used in many embedded applications, including in power management, office machines, and portable electronics. In these applications, the capacitor helps to filter high-frequency noise, provide input and output (IO) filtering, and store energy. The capacitor also helps to supply fast rising and falling current pulses, and to smooth out switch-mode power supplies.

Working Principle

The working principle of the 179D106X0010B6V1 tantalum capacitor can be broken down into three individual components; namely, the anode, the cathode, and the dielectric. The anode is a solid sheet of tantalum metal which serves as a conductive electrode. This portion of the capacitor is positioned closest to the positive terminal of a power source. Meanwhile, the cathode of the capacitor comprises a porous layer of tantalum metal which has been impregnated with a wetting agent like manganese dioxide. This layer helps to further conduct current from the anode to the cathode. The dielectric of the tantalum capacitor is a layer of thin oxide film that forms an insulating layer between the anode and the cathode of the capacitor. When a voltage is applied to the capacitor, the oxide film polarizes, meaning it will draw electrons away from the anode and towards the cathode. This allows a current to flow through the capacitor, which is then stored as electrical energy. The 179D106X0010B6V1 tantalum capacitor is also durable and reliable due to its high thermal and voltage ratings, as well as its hermetically sealed contained epoxy coating. This coating prevents moisture, dirt, and other contaminants from entering the capacitor and damaging its internal components. The combination of all these components allows the capacitor to provide excellent voltage and temperature stability, meaning it can operate in a wide range of conditions without compromising performance.
