The resistance material has a certain structural form, and the current two -terminal and two -terminal electronic component components that pass through the current through the effect. The resistance value can be changed. It is called a fixed resistor resistor. Essence Essence The resistor resistor resistor is selected by multi -component components in electronic circuits. It is mainly used to regulate and voltage, voltage voltage voltage voltage voltage voltage voltage voltage voltage and voltage voltage-current current voltage component component component component component component composition
First, the resistor guidelines
Different resistors, different potentiocators can be alloyed, and the three -three types of categories are also different. When using a fixed resistor.
Second, choose according to the characteristics
1. Use resistor resistance and error use
Resistance: The principle is that the smaller the difference between the nominal and the resistance of the demand.
Error selection: RC RC circuit circuit needs to be as small as possible.
2. Select the parameters of the resistor
Rating: When the voltage exceeds the fixed voltage, even if it is met, the resistor requires, the resistor resistor will be broken and damaged.
Rating: The selected resistor rated the actual power of the actual power to ensure that the resistor works in the middle and long term of the circuit
1. Choose according to the characteristics
High frequency: The smaller the distribution, the better the film resistance metal oxide film resistance. Essence Essence
Low -frequency: Wind resistance Wind -resistant carbon membrane is applicable.
Filter circuit: There is no strict, any resistor resistor. Essence Essence
Power circuit circuit, circuit: circuit circuit require
