Carbon film resistors are electronic components that limit the flow of electric current in a circuit. They are made by depositing a thin layer of carbon onto an insulating substrate, which creates a resistive path. This design allows for precise control of resistance values, making them suitable for various applications in electronics. These resistors are known for their stability and reliability, offering good performance in terms of temperature and voltage. They are commonly used in consumer electronics, audio equipment, and telecommunications due to their low noise and compact size, making them a popular choice among engineers and designers.
