What Is a Precision Resistor?
A precision resistor is a component designed for exact resistance in electrical circuits.
Unlike standard resistors, which have broader tolerances, precision resistors boast near-perfect resistance values, essential for applications demanding high accuracy. These resistors stand out for their minimal error margin and the ability to maintain consistent resistance despite environmental changes, crucial for precision measurement and control in electronic devices and instruments.
There are two main types of precision resistors: fixed, offering a stable resistance value, and variable, which permit adjustments to resistance. Both types play pivotal roles in high-precision applications.
