Film resistor Selection

When selecting Film resistor, you can use the following parameters (such as 0402_4.42KΩ_±1%_1/16W_±100ppm/℃ ）Choose the corresponding type. High frequency circuits are suitable for metal film resistors or metal oxide film resistors, while low-frequency circuits are suitable for wire wound resistors or carbon film resistors, and wiping should also be considered. During the selection process, attention should also be paid to ensuring that the selected resistor model has at least two or more suppliers or corresponding replacement models in the market to prevent stockouts.
