FAQ about Chip Resistor - Surface Mount
-
1. 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. -
2. Working principle of chip fixed resistors
The working principle of chip fixed resistors is based on Ohm's law, that is, the relationship between voltage (V), current (I) and resistance (R) is V=I×R. This resistor is a two-terminal passive component used to implement resistance like a circuit element. The current flowing through the resistor is proportional to the voltage across the resistor. Therefore, this relationship can be simply expressed using Ohm's law. For example, if a 100-ohm resistor is connected across a potential difference of 10 volts, a current of 0.1 amperes flows through the resistor.
Chip fixed resistors, commonly known as chip resistors, are one type of metal glass uranium resistors. It is a resistor made by mixing metal powder and glass uranium powder and printing it on a substrate using screen printing. This resistor is resistant to moisture and high temperature and has a small temperature coefficient. Its manufacturing process includes mixing metal powder and glass uranium powder, and then printing these mixtures on a substrate by screen printing to form the desired resistance value. This design enables chip fixed resistors to work stably in various environments, including humid and high temperature conditions, while maintaining a small temperature coefficient to ensure the stability of the resistance value. -
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".
