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. 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. ‌

• 2. Resistors Guide

  When interpreting the digital identification of chip resistors, you need to pay attention to the following points:
  1. Make sure to correctly identify each digit in the digital identification to avoid misreading and misjudging the resistance value or accuracy.
  2. Be familiar with the digital representation methods corresponding to different accuracy levels so that you can quickly and accurately judge the tolerance accuracy of the resistor.
  3. In actual applications, you also need to consider the operating temperature range, power and other parameters of the resistor to ensure its stable and reliable performance.
