High-frequency circuitry, and circuits with high quality and working stability, high reliability requirement, the smaller the distribution parameters, the better the metal film resistance or the metal oxide film resistance.
The low frequency circuit, and electronic lines with high performance requirements can be used with a winding resistor and a carbon film resistance.
Power amplifying circuit, bias circuit, sampling circuit on stability requirements, resistors having a small temperature coefficient;
The decoupling circuit, the filter circuit has no strict requirements for the resistance change, and any resistor is applied, and the resistance is selected according to the size of the board.
The principle of resistance resistance of the resistor resistor can change the small power resistor, but the electrical resistance for insurance; the metal film resistor can be changed to the carbon film resistor; the fixed resistor and semi-adjustable resistor can be replaced with each otheruse.
