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".

4. 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.
