Chip resistance-surface Mount (Chip resistance-surface mount) Surface Mount is an electronic component assembly technology in which the Resistor and other components are directly pasted to the surface of the printed circuit board. There is no need to reserve the pupil for the original, and the electrical connection is realized by brazing, which greatly improves the integration and processing speed of the circuit board. In the circuit, the chip resistor can not only stabilize the current and voltage, prevent excessive current or voltage from causing damage to the chip, but also carry out impedance matching in signal transmission to ensure that the signal is smooth and without loss. In addition, the chip resistance can also filter out the interference signal, improve the anti-interference ability of the system, and ensure the stability and reliability of the circuit. Surface mounting of chip resistance can greatly improve the efficiency of chip resistance.

Chip resistance-surface Mount has a wide range of applications, It is widely used in communication equipment (such as mobile phones, TV sets), computer equipment (motherboard, graphics card), automotive electronics (engine control unit, braking system), industrial control (PLC, sensor) and medical equipment (electrocardiograph, blood pressure monitor) and other fields. Its compact size and high-precision characteristics enable electronic equipment to be further miniaturized and refined to meet the diversified needs of modern science and technology.

• 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. 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 digital identification interpretation example

  To better understand the interpretation method of chip resistor digital identification, let's look at an example. Assuming that the digital identification on a chip resistor is "1001", what is the resistance value of this resistor? What is the accuracy?
  First, we interpret the first three digits "100", indicating that the resistance value is 100 ohms. Next, we look at the last digit "1", which indicates that the tolerance accuracy of the resistor is 1%. Therefore, the resistance of this chip resistor is 100 ohms and the tolerance accuracy is ±1%.
