What is a precision resistor and what are the common types of precision resistors? 2

3. Wire wound resistance:

Wire wound resistors are made by winding thin metal wires (such as nickel chromium alloy) around a non-conductive core. This type of resistor can achieve very high precision, with tolerances typically ranging from 0.1% to 1%. Their temperature coefficient is relatively low, making them suitable for high-precision measurement and control applications.diode

4. Thin film resistor:

Thin film resistor is an ADS8412IBPFB resistor made by depositing a layer of resistive material (such as metal or oxide film) on an insulating substrate. This type of resistor has good temperature stability, with a tolerance range typically between 0.1% and 1%, making it suitable for applications that require high precision and stability.diode

5. Carbon film resistor:

Although carbon film resistors are not the most precise type of resistor, they can still be considered as precision resistors in certain applications. They are made by coating a layer of carbon film on ceramic materials, with lower tolerance and temperature coefficient than the aforementioned resistance types, but they are a feasible choice in cost sensitive applications.diode
