Metal film resistors are usually coated with nickel chromium (NiCr), but might be coated with any of the cermet materials listed above for thin film resistors.5 %) for an Compared to other resistor types such as metal film, the wire diameter is relatively large and, therefore, is more robust. And looking for guidance on what to test for as a reduction in performance. Resistors 101 A metal film resistor consists primarily of an evaporated coating on aluminum that acts as the resistance material with additional layers that provide insulation protection from heat and a current-carrying coating to complete the package. By this method, tighter resistance tolerances can be achieved. Common carbon film resistors are mostly yellow or pink due to their low accuracy and low production costs, while most metal film resistors are blue. 0. Metal film resistors are usually coated with nickel chromium (NiCr), but might be coated with any of the cermet materials listed above for thin film resistors.
