When is gold resistance better? When will carbon resistance be better?
The gold resistance is of high accuracy, but the price is high. The resistance value of the carbon resistor is low, but it is cheap!
Metal film resistance, high precision, overload capacity, high temperature coefficient, but the price is also higher. Commonly used in some demanding or more accurate circuit, such as instrumentation, precision power supply. Carbon film resistors have high cost performance and low cost, but they have larger errors. A large number of applications in civil electrical products. Such as television, air conditioning, stereo and so on.
