What if the resistor overheats?

Overheating of the resistor may cause the performance of the resistor to decline or even damage. The causes of overheating resistors may include overload flow, unreasonable circuit design or poor heat dissipation conditions. When it is found that the resistor is overheating, the first solution is to find out the cause of the heat generation and solve it. For example, the current passing through the resistor can be reduced, the circuit layout can be optimized to reduce power consumption, or the heat dissipation design can be improved.
