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. -
2. What is the number of chip resistors?
Chip resistors are one of the commonly used components in electronic circuits, and their digital identification is an important basis for identifying resistance values and accuracy. The digital identification is usually printed on the surface of the resistor and consists of several digits. These digits not only indicate the specific resistance value of the resistor, but also imply the tolerance accuracy information of the resistor.

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".
