Detailed explanation of the comparison table and reading method for SMT resistance values

Introduction

SMT resistors are a common electronic component widely used in various electronic products. This article will provide a detailed introduction to the resistance comparison table of SMD resistors and how to correctly read the resistance value of SMD resistors, helping everyone better understand and use SMD resistors

1、 Comparison Table of Chip Resistance Values

The following is a common comparison table of SMD resistance values, which includes different SMD resistance models and their corresponding resistance ranges:

|100 | 0.01|

|475 | 0.475|

|1k | 1.0K|

|3.3K | 3.3K |

|10k | 10.0K|

|22k | 22.0K|

|33k | 33.0K|

|50k | 50.0K|

|75K | 75.0K|

|100k | 100.0K|

|150k | 150.0K|

|220k | 220.0K|

|270k | 270.0K|

|330K | 330.0K|

|500k | 500.0K|

|800k | 800.0K|

|1kk | 1.0K Ω|

|1m Ω | 1.0M Ω|

|10m Ω | 10.0M Ω|

2、 Reading method for SMT resistance

1 Firstly, it is necessary to use a multimeter to test the resistance value of the chip resistor. Before testing, ensure that the dial of the multimeter is set to resistance measurement mode and select the appropriate range. Normally, it is recommended to choose a range slightly larger than the target resistance value in order to make appropriate adjustments during the measurement process

2 Insert the resistance of the patch to be tested into the circuit to ensure good contact. If possible, a soldering iron can be used to fix it onto the circuit board to improve stability

3 Contact the probe of the multimeter to both ends of the resistance of the patch to be tested. In some cases, it may be necessary to adjust the position of the multimeter to maintain a certain distance from one end of the resistor. This can be achieved by rotating the knob on the multimeter. Please note that the probe should not be placed close to other components or circuits to avoid short circuits or interference

4 Observe the reading on the multimeter, which is the actual resistance value of the chip to be tested. If the reading does not match the values in the comparison table, you can try adjusting the knob of the multimeter or replacing it with another model of SMD resistor for testing
