A Thick Film Resistor is an electronic component used to limit the flow of electric current in a circuit. It is made by applying a thick layer of resistive material onto a ceramic substrate. This design allows for precise resistance values and is commonly used in various applications, including consumer electronics and automotive systems. These resistors are known for their durability and stability under different environmental conditions. They can handle high temperatures and are often used in surface-mount technology (SMT) due to their compact size. Their reliability makes them a popular choice in modern electronic devices.
