Can high-power resistors replace thick film resistors? To answer this question, we cannot simply give a "yes" or "no" conclusion, but need to have a deep understanding of the core characteristics and application scenarios of these two types of resistors.
Power resistors are energy dissipation devices specifically designed for high-power circuits, with thermal management as their core design principle. According to different materials and structures, high-power resistors can be divided into the following categories:
For the mainstream models in the market you have listed, the power options of 1206 packaged 10 Ω resistors and their advantages compared to ordinary 0.25W thick film resistors are as follows:
The following is a list of models and parameters for the 1206 packaged 22R high-power resistor (classified by brand, without using a table):
Based on the 0402 1R resistor model and parameters you provided, combined with the requirements of the application scenario, the following is a detailed parameter analysis and selection recommendation:
