2. Key points of selection
Confirm power requirements: If the circuit design power exceeds 1W, prioritize the 2W specification to avoid resistor overheating and damage;
Matching accuracy requirements: For non precision measurement scenarios (such as motor current limiting and power supply voltage division), ± 5% accuracy can meet the requirements. For precision control scenarios, ± 1% accuracy models of the Tiantong series can be considered;
Pay attention to packaging adaptation: The 2512 package size is relatively large, and it is necessary to confirm the reserved space on the PCB board. If the space is limited, the 1210 package 1W model can be considered, but the power margin needs to be re evaluated;
Verify brand qualifications: Prioritize the use of original authentic channels to avoid performance non-compliance and safety hazards caused by counterfeit products.
