Tantalum Capacitors

Tantalum capacitors are one of the most common types of electrolytic capacitors. They derive their name from their key material – Tantalum – which is a rare and expensive element. Tantalum capacitors have the highest Capacitance-Voltage ratio compared to most electrolytic capacitors, making them great for high power applications.The most common type of tantalum capacitor is the ‘wet electrolytic’, which operates by using a very thin layer of dielectric material between two conductive plates separated by an electrolyte solution. The dielectric material is usually an oxide or a polymer (often a tantalum pentoxide). The capacitor is charged when a voltage is applied, and then stored in the form of an electrical field within the dielectric material.The 299D156X0016CB1E3 tantalum capacitor is a type of wet electrolytic capacitor. The first 3 digits in the part number (299) indicate the minimal capacitance value in µF (micro Farad). This value is usually followed by a letter or character indicating tolerance for the specific capacitor. In this case, the letter is ‘D’ which stands for ±20% tolerance.The second part of the part number (156) stands for the maximal working voltage. This value is expressed in volts. In this case, the maximal working voltage of the capacitor is 160 volts DC (156 x 10V = 160V).The third part of the part number (0016) refers to the physical dimensions of the capacitor. The length and width of the capacitor are indicated as “x10”, so 0016 would stand for 16 x 10 or 16mm x 10mm.Finally, the last two digits in the part number (CB) stand for its maximum working temperature, usually expressed in °C. In this case, the CB indicates a maximum working temperature of 85°C.The 299D156X0016CB1E3 tantalum capacitor has a wide range of applications, from medical equipment and computers to audio electronics and telecommunications. It is preferred for its high capacitance-voltage ratio and wide range of working temperature. The capacitor also has a fairly long useful life, making it an economical choice for most applications.
