What is a precision resistor and what are the common types of precision resistors? 3

When choosing a precision resistor, the following factors need to be considered:

Tolerance: Represents the maximum allowable deviation percentage, with lower tolerance indicating higher accuracy.

Temperature coefficient: It represents the degree to which the resistance value changes with temperature, and a low temperature coefficient means that the resistance value remains stable when the temperature changes.diode

Stability: The degree of change in resistance value after long-term use, and high stability is crucial for maintaining the long-term performance of the circuit.

Power rating: The maximum power that a resistor can withstand.

Size and shape: Choose according to specific installation requirements and space limitations.diode

Precision resistors have a wide range of applications and play a crucial role in ensuring the performance, reliability, and accuracy of electronic devices. The correct selection and application of precision resistors is a crucial step in improving the quality of electronic design.diode
