Common problems

Resistor break is usually caused by long-term overload flow or external force impact. In this case, it is usually necessary to replace the damaged resistor with a new one. When replacing the resistor, in addition to ensuring that the resistance value of the selected resistor is correct, it is also necessary to consider its power level to ensure that it can withstand the actual operating conditions in the circuit.

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.

Resistance drift refers to that the resistance value of the resistor changes and does not remain at the original exact value during use. This may be due to environmental factors such as temperature, humidity, or the aging of the resistor itself. In order to solve this problem, it is first necessary to check and control the circuit working environment to ensure that conditions such as temperature and humidity meet the working requirements of the resistor. You can consider using a resistor with higher accuracy and better temperature coefficient, or using a temperature compensation circuit to reduce the influence of the external environment on the resistor.

Established by IEC (International Electrotechnical Commission), this refers to the resistance value determined based on the standard E Series preferred numbers.

Resistors are components that act to impede the flow of electricity.

Shunt resistors are ultra-low ohmic resistors typically used for current sensing.
