Thick film resistors are electronic components used to limit the flow of electric current in a circuit. They are made by applying a thick layer of resistive material onto a ceramic substrate, which provides stability and durability. These resistors are known for their compact size and ability to handle high power levels, making them suitable for various applications in electronics. These resistors are commonly used in printed circuit boards (PCBs) and can be manufactured with precise resistance values. Their performance is reliable across a wide range of temperatures, and they are often preferred for their cost-effectiveness in mass production.
