1.Introduction:
Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The
metal is renowned for its resistance ,as the metal powder, is in the production of electronic components, mainly
capacitors and some high-power resistors. Tantalum electrolytic capacitors exploit the tendency of tantalum to form
a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor,
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 capacitors
are attractive for portable telephones, personal computers, and automotive electronics.
