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

2. Metal foil resistor:

Metal foil resistors are made by attaching extremely thin metal foil material onto an insulating substrate. They provide extremely low temperature coefficients and high precision, with tolerances as low as 0.005%. Metal foil resistors are highly suitable for applications that require extremely high precision, stability, and response speed.diode

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
