Thin film resistors are electronic components that provide resistance in a circuit. They are made by depositing a very thin layer of resistive material onto a substrate, which can be made of materials like glass or ceramic. This thin layer allows for precise control of resistance values, making them ideal for applications requiring accuracy and stability. These resistors are commonly used in electronic devices, sensors, and precision measurement equipment. Their small size and ability to handle high frequencies make them suitable for modern technology, where space and performance are critical. Thin film resistors also exhibit low noise and excellent temperature stability.
