modname=ckeditor1, according to the spectral characteristics of three photoresistor photoresistor: UV light-sensitive resistors, infrared light-sensitive resistors, Visible photoresistor;
2, the main parameters are as follows:
A, dark current, the dark resistance: photoresistor at a certain applied voltage, when no light irradiation, when flowing Current is called dark current. Applied voltage and the dark current ratio is called dark resistance;
B, Sensitivity: Sensitivity refers to the resistance value of the photoresistor from light irradiation (dark resistance) when irradiated with light and the Resistance (light resistance) of the relative change value.
C, voltage characteristic curve. Volt-ampere characteristic curve used to describe the relationship between the applied voltage and the photoresistor photocurrent, of The photosensitive device, its photocurrent increases with the applied voltage.
D, the temperature coefficient. Photoelectric effect photoresistor influenced by temperature, partial photoresistor optoelectronic at low temperatures Higher sensitivity, whereas the sensitivity at high temperatures are lower.
E, rated power. Refers to the rated power for a certain line photoresistor allowed power consumed, when the temperature rise High, its power consumption is reduced.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
