WebAn Introduction to Carbon Composition Resistors. Carbon composition resistors (CCR) are fixed value resistors. They are made out of fine carbon particles mixed with a binder (for example clay). After baking, it has a solid form. Although carbon composition resistors are widely applied in circuits, the majority of resistors today are made by ... Web5 de mai. de 2024 · Thick-Film Resistors. Thick-film resistors have received a significant amount of attention for high-temperature applications in recent years. These resistors are made by depositing a blend of metal and particles onto a ceramic substrate and firing at a high temperature (typically 850°C or so in the air) which creates a conductive cermet matrix.
