Detailed explanation of chip resistor screen printing model comparison table

With the continuous development of electronic products,Chip resistorAs one of the most commonly used electronic components, its model identification has become particularly important. patchresistanceSilk screen models not only help engineers quickly identify resistor values, but also effectively improve production efficiency and product quality. This article will introduce the comparison table of chip resistor screen printing models in detail to help everyone understand and apply it accurately.

1. Basic concepts of chip resistor screen printing models

The silk screen model number on the chip resistor is an identification method that uses a combination of numbers and letters to indicate its resistance value and accuracy. Due to the small size of chip resistors, it is impossible to directly mark the complete resistance value, so a simplified coding method is used. Common silk screen models include a combination of three or four digits, which are converted into resistance values ​​through specific rules.

2. Analysis method of three-digit silk screen model number

The three-digit silk screen model number is the most common representation, with the first two digits representing significant digits and the last digit representing the multiplication to the power of 10. For example, "103" means 10×10³=10,000 ohms, which is 10kΩ. This method is suitable for chip resistors with a wide range of resistance values ​​and is easy to identify and apply.

3. Usage scenarios for four-digit silk screen models

The four-digit silk screen model is usually used for chip resistors with higher resistance value accuracy, especially those with smaller resistance values ​​or special resistance values. The first 3 digits represent significant figures, and the last digit is the multiplier. For example, "1001" means 100×10¹=1000 ohms, which is 1kΩ. Four-digit coding provides finer resistance differentiation.

4. Model designation combining letters and numbers

Some special chip resistors use a screen printing method that combines letters and numbers. The letters usually represent the unit or specific parameter of the resistance, such as "K" representing kiloohms and "M" representing megaohms. At the same time, the letters may also indicate the tolerance level or temperature coefficient of the resistor, helping engineers quickly judge the performance of the resistor.

5. The practical value of the chip resistor model comparison table

Through the screen-printed model comparison table of chip resistors, users can quickly convert the silk-screened code into a specific resistance value, reducing search time and avoiding circuit failures caused by misjudgment. The comparison table also facilitates inventory management and purchasing, ensuring that the required resistor type is accurate.

6. How to correctly read the screen-printed model number of chip resistors

When reading screen-printed models, pay attention to font clarity and coding rules to avoid misjudgments caused by blurred printing or misreading of numbers. It is recommended to use a professional comparison table or use electronic component identification tools to improve identification accuracy.

7. Examples of common chip resistor resistance values ​​and corresponding silk screen models

For example, 1Ω corresponds to the silk screen "1R0", 10Ω corresponds to "100", 100Ω corresponds to "101", 1kΩ corresponds to "102", 10kΩ corresponds to "103", 100kΩ corresponds to "104", and 1MΩ corresponds to "105". Familiarity with these common models will aid in quick identification.

8. International standards for screen printing models of chip resistors

There may be differences in silk screen markings between different manufacturers and regions, but most follow international electronic component coding standards (such as EIA-96). Understanding these standards facilitates cross-border procurement and application and improves compatibility.

Chip resistor screen printing model comparison table is an indispensable tool in the electronic design and manufacturing process. Accurate understanding and application of silk screen models not only improves work efficiency, but also ensures stable circuit performance. I hope this article’s analysis of chip resistor screen printing models can help readers better identify and use chip resistors and promote the high-quality development of electronic products.
