This November, our company will attend Electronica2008 in Munich, Germany. At this fair, we will strongly recommend our Tantalum Capacitor to visitors and customers from all over the world. Especially TS19 Dipped Tantalum Capacitor and and TS20 Chip Tantalum Capacitor will be our focus. From the sales performance of 2008 first half year, the two Tantalum Capacitors bring us very good business and customers’ comment to the two series is satisfactory , these bring us more confidence to expand our market for Tantalum Capacitors all over the world, especially in Europe and in America.
Tantalum capacitors are a form of electrolytic capacitor. However, some forms of them are non-polar, containing two capacitors connected in series (negative to negative). In comparison with aluminium electrolytic capacitors, they are for similar capacitance and volume ratings generally more expensive, with lower effective series resistance. They usually have longer life, especially at moderately elevated temperatures. For surface mount devices, they are generally smaller.
Tantalums exploit the tendency of tantalum to form a protective oxide surface layer. They use tantalum powder, pressed into a pellet shape, as one “plate” of the capacitor with the oxide as the dielectric, and an electrolytic solution or conductive solid as the other “plate”. Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, Tantalum Capacitor is useful in portable telephones, pagers, personal computers, and automotive electronics.
