Tantalum capacitors, or tantalum electrolytic capacitors, are a type of electrolytic capacitor, a component of electronic circuits. They are made with a tantalum metal oxide as the electrolyte, as opposed to liquid electrolyte in you typical electrolytic capacitor. This makes them rugged and able to withstand higher temperatures and the effect of mechanical shocks and vibrations. In addition, they are self-healing and have a very long service life. All these features make TA tantalum capacitors the ideal choice for many industrial and commercial applications.

TDC226M035WSG, by KEMET Corporation, is a surface mount capacitor that falls under the category of tantalum capacitors. It is a 25 V, 15 uF, ±20% capacitance tolerance capacitor and comes in a molded SMD tape and reel. This capacitor can be used in various applications such as switch mode power supply, inverter, voltage regulators, defibrillators, and motor controls.

The TDC226M035WSG utilizes tantalum metal oxide as the dielectric material which helps to store electrical charge. It also features an etch-back anode construction which provides the incredible stability permitted by surface mount technology. The anode termination is compatible with virtually all soldering profiles including lead-free varieties.

This capacitor has superior temperature stability compared to other capacitors and offers a better resistance to ripple current and lower ESR. The solid construction also helps to provide increased reliability and extended life. Moreover, the rugged design makes it suitable for use in a wide temperature range from -55℃ to 125℃.

The working principle of TDC226M035WSG can be broken down into four stages. First, when connecting a positive voltage to the anode of the capacitor, the anode terminal emits electrons which help to create an oxide layer on the anode. This oxide layer acts as an insulator and prevents further current flow. Second, when connecting the anode voltage to zero and then to a negative voltage, electrons from the negative terminal are drawn to the anode and the oxide layer is reduced. Third, when the negative voltage is reduced to zero, charge on the capacitor’s plates is restored and the oxide layer begins to rebuild itself. Fourth, when the voltage on the capacitor is reduced to zero, the oxide layer is completely restored. Although this process is repeated an infinite number of times, the capacitance of the capacitor remains the same due to the capacitance factor.

In conclusion, the TDC226M035WSG capacitor by KEMET is one of the most reliable and versatile capacitors available. It can be used in a wide range of applications including switch mode power supplies, adjustable DC power supplies, motor control systems, and more. It offers superior temperature stability with a wide temperature range as well as extended life and increased reliability.
