Tantalum

Tantalum nitride resistors are more rugged and more chemically and thermally resistant than nichrome resistors. A passivating tantalum pentoxide layer (Ta 2 O 5) is formed by annealing the resistors in air or in oxygen or by introducing controlled amounts of oxygen during the reactive sputtering process. Annealing is performed at 450°C or higher.
