Chip resistors are commonly used electronic components used to control the resistance value in a circuit. The working principle involves depositing a thin film material on an insulating substrate, and then cutting the film into resistors with specific shapes and sizes through photolithography and etching processes. This design enables high precision and stability resistors, suitable for various circuit applications.The working principle of chip resistors mainly includes the following aspects:1. Material selection: The resistance value of chip resistors depends on the resistivity and thickness of the thin film material. Common thin film materials include nickel-chromium alloy, chromium-silicon alloy, etc., which have stable resistivity and good high-temperature resistance, suitable for circuit applications in various environmental conditions.2. Manufacturing process: The manufacturing process of chip resistors includes thin film deposition, photolithography, etching, and other process steps. Firstly, deposit a layer of thin film material on the insulating substrate, then use photolithography to cut the thin film into resistors with specific shapes and sizes, and finally remove the excess thin film material through etching to form the final resistor structure.3. Resistor characteristics: Chip resistors have characteristics such as high precision, high stability, and low temperature coefficient. Due to the uniformity and stability of the thin film material, the resistance value of chip resistors can achieve high accuracy, usually within 1%. In addition, chip resistors have a low temperature coefficient, which can maintain a stable resistance value over a wide temperature range.4. Application areas: Chip resistors are widely used in various circuits, such as analog circuits, digital circuits, power electronic circuits, etc. They can be used as voltage dividers, current limiters, signal regulators, and other functional components, providing flexibility and reliability for circuit design.In conclusion, chip resistors are high-performance electronic components with precise manufacturing processes and stable resistance characteristics. They play an important role in circuit design, ensuring the performance and reliability of electronic products.
