Film Resistor
Film Resistor
Thick-film resistors are often overcoated with a glaze material (typically a borosilicate glass) to protect them against the environment, chemical attack, and mechanical abrasion. Thin Film and Thick Film Thin film resistors are created using a technique called sputtering which permits a very thin and controlled layer of a material, tantalumnitride or Nichrome, to be deposited onto a substrate. The environment in which the film is laid and without the necessity for high power laser trimming ensures a very stable and accurate resistor. Thick film resistors are constructed from a resistive paste which is printed onto an insulating substrate and then fired. The...
