1. Characteristics of chip fixed resistors?
Characteristics of chip fixed resistors mainly include small size, light weight, adaptability to reflow soldering and wave soldering, stable electrical performance and high reliability, low assembly cost, compatibility with automatic mounting equipment, high mechanical strength, and superior high-frequency characteristics.
Chip fixed resistors are small and light, which facilitates the layout and installation of circuits and saves space. Adapting to the technical requirements of reflow soldering and wave soldering makes them highly applicable in modern electronic manufacturing processes. The stability and high reliability of electrical performance ensure the long-term stable operation of the circuit and reduce the failure rate. The low assembly cost and compatibility with automatic mounting equipment improve production efficiency and reduce manufacturing costs. -
2. What are the functions of chip fixed resistors?
Chip fixed resistors (chip resistors) play a vital role in electronic devices and systems.
Chip fixed resistors, also known as Chip Resistor, are one of the passive electronic components widely used in the modern electronic manufacturing industry.
1. Voltage division and current shunting: When the chip resistor is in series or parallel with other components such as light bulbs in the circuit, it can play the role of voltage division and current shunting. In a series circuit, the chip resistor shares the voltage with another component; in a parallel circuit, the chip resistor shares the current with other components.
2. Impedance matching: During the signal transmission process, the chip resistor helps to achieve the matching of the load impedance and the internal impedance of the excitation source by adjusting the impedance, thereby optimizing the signal transmission efficiency.
3. Filtering: In the RC charging and discharging circuit composed of a resistor and a capacitor in series, the chip resistor plays a filtering role, helping to stabilize the voltage and current in the circuit and reduce fluctuations and interference.
4. Special resistor functions: Special types of chip resistors, such as resistors made of semiconductor materials, have variable resistance values and are used to achieve more complex circuit functions, such as impedance control.
5. Save space and improve reliability: Due to the small size and light weight of chip resistors, circuit space costs can be greatly saved, making the design more refined. At the same time, its ability to adapt to reflow soldering and wave soldering improves the reliability and efficiency of production. -
3. Resistor tolerance accuracy representation method
The tolerance accuracy of chip resistors refers to the allowable deviation range between the actual value of the resistor and the nominal value. In the digital identification, the tolerance accuracy is usually indicated by the last one or two digits. These numbers correspond to different accuracy levels, for example, 1% accuracy is usually indicated by the number "1", while 0.1% accuracy is indicated by the number "01".
