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. What is a Chip Resistor?

  Chip Resistor, also known as chip fixed resistors, are resistors designed for surface mounting. They can be mounted directly to the surface of a printed circuit board (PCB) without drilling holes like traditional through-hole components.
  
  Such resistors are usually much smaller than traditional resistors, so they take up much less space on the circuit board. The use of SMD resistors is due to the invention of surface mount technology (SMT), which not only reduces the size of components, but also greatly reduces the time to manufacture circuits. SMD resistors are mainly used in professionally manufactured PCBs, while through-hole resistors are more commonly used in most homemade circuits because they are more convenient to install and do not require specialized equipment.
  
  There are many ways to express the resistance value of SMD resistors, including direct marking, three-digit digital representation, four-digit digital representation, EIAJ code representation, etc. These methods enable the resistance value of the resistor to be clearly marked on the resistor for easy identification and use. In addition, SMD resistors are also resistant to moisture and high temperatures, and have a small temperature coefficient, which allows them to maintain good performance in various environments.

  ‌6. Chip current sensor‌: used to detect the current in the circuit, with low temperature coefficient (TCR) characteristics.

• 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".
