First, the resistor selection
1. Selection of fuse resistors
Electricity on a certain protective effect, selects the performance of performance performance and performance, and according to its performance, performance, performance, performance performance Performance performance Performance performance Double dual dual dual dual dual dual dual dual dual double circuit circuit circuit circuit circuit circuit circuit specific specific specific requirements Choose its resistance value and resistance, etc. Normal conditions such as stable work resistance and excessive work resistance, otherwise it will be great
2. Select the fixed resistor
Select species, select a resistor resistor of the type type one, and the requirements of the circuit circuit of the circuit circuit that are due. The high -frequency circuit should use a distributed inductance and inductance amplification response. The wire winding is compared with a wire, the current resistor or a high -power resistor. Compared with wire -wiring electrocarrings resistors, it is mostly used for fixed attenuation device attenuers, resistors, and the calculation value of each electrical circuit computing value. The resistor of the series series. Essence The resistor in the precision instrument and special circuit circuit uses the resistor resistor to choose from, and the general requirements are generally required. Generally, it is required to increase the power power power of the resistor resistor at will. Essence Essence Ruocu circuit circuit requires a power type power -type resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor
3, electrical choice pressure
The major parameter parameters of the main electronic products in the main electronic products in each electronic product include the nominal nominal voltage voltage, the largest continuous working voltage, the maximum and biggest requirements, especially the voltage is accurate.高高，压敏高高高高起起到到过电压电压保护作用标称电压电压过过低低低低低低
4. Choose the optical resistor selection
Selecting electricity should determine the type of resistance in the application. Essence
5. Wetmine resistor selection
When selecting, the block first is based on the requirements of the application. Essence For example, for example, for example, for the washing machine washing machine ,,,,, dry clothing machine drying machine appliances and appliances of appliances and humidity humidity and humidity detection of humidity, humidity humidity, and medium environment of constant humidity machines. Resistors;; for detecting detection and detection resistors in meteorological meteorological meteorological monitoring and monitoring and monitoring, video recorder video recorder, etc.
Selection of thermistor
There are many types and models of thermistor resistance, and should be appropriately selected according to the specific requirements of the circuit. Positive temperature coefficient thermistor is generally used for the launch circuit of the refrigerator compressor, the color of the color of the color of the color TV, the electrical motor over -circuit, the current restricted circuit, and the electric heating circuit. Essence Commonly used in circuits in the circuit, commonly used thermal heating thermistor, heating thermistor, electromododlectronics, electromododlectronics, electromododlectronics electrocrolers and electrocrolers resistors Resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor block Resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor block Resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor resistor block The resistor can be used to start with the compressor.

Second, resistor detection
1. Detection of fixing and fusion resistors
The main melting, the measurement of the main resistor resistor resistor measurement of the resistor is measured, when the resistance value is measured, it can be measured. Essence
The measured resistance values ??that are measured do not match, then the error error error error of the resistor is large or the value has been changed;; if the resistance value of the resistor is measured
2. Sensitive resistor detection and testing
(1) NTC thermist sensitivity detection detection
At the same time, NTC measures the thermoltage and thermoltage at the same time, at the same time, use pinching the resistor or using electricity at the same time, and the hair dryer is smaller according to its temperature and temperature. Then change changes and changes and changes
2) The test of the table with a meter with a meter with a meter with a meter or a R × R × 10K file for the meter of the surface of the voltage pressure
((3) PTC thermal electricity detection detection and detection
The PTC thermistor is measured with a table ×× file with a table ×× file with a table ×× file with a table ×× file. If the electricity is large and large, it is heated with electricity iron. For use of induced and induced, for use, use for use. Essence Resistor.
