With the continuous development of electronic products,Chip resistorAs one of the basic electronic components, its model identification has become particularly important. especially throughresistanceThe silk screen model can quickly identify the resistance value and specifications of the resistor, which can greatly improve production and maintenance efficiency. This article will give you a detailed introduction to the latest comparison table of chip resistor screen printing models to help you better understand and apply this important information.
1. Basic concepts of chip resistor screen printing modelsThe silk screen model number of chip resistors refers to the code printed on the surface of the resistor to identify its resistance value and other parameters. Due to the small size of chip resistors, it is difficult to directly mark the complete resistance value, so a simplified combination of numbers and letters is used to represent the resistance value. Understanding the meaning of these models is the basis for correct selection and replacement of resistors.
2. The latest screen printing model coding rules for chip resistorsThe latest silk screen models are usually represented by three or four digits, where the first three digits represent significant digits and the last digit represents the power of 10 multiplied by. For example, "103" means 10×10^3=10kΩ. Some models will also add letters to indicate tolerance levels or special properties, such as "R" representing the decimal point position.
3. Comparison table of common chip resistor screen printing models| Silk screen model number | Resistance value (Ω) | Remarks |
|---------|-----------|-------|
| 100 | 10Ω | Direct numerical value |
| 472 | 4.7kΩ | 47×10^2 |
| 105 | 1MΩ | 10×10^5 |
| 0R0 | 0Ω | Connecting line |
This table is a basic comparison, and actual application must be combined with specific manufacturer standards.
4. The meaning and application of letter logosIn addition to numbers, common letters in silk screen printing such as "J", "K", and "M" represent tolerance levels of ±5%, ±10%, and ±20% respectively. In addition, "F" represents ±1% accuracy, and some high-precision resistors will use these markings. Understanding the meaning of the letters can help you choose a resistor that meets your circuit's needs.
5. Special models with multi-digit and letter combinationsSome high-resistance or special resistors use model combinations with letters, such as "1K5" indicating 1.5kΩ, and "4R7" indicating 4.7Ω. This type of logo is simple and intuitive, easy to identify quickly, but please pay attention to the letter "R" in the decimal point position.
6. How to use silk screen models to quickly select modelsAfter mastering the silk screen model correspondence table, you can quickly determine the resistance value through the markings on the resistor surface, avoiding the need to consult complicated information. In addition, combined with the circuit drawings and design requirements, the resistor values and tolerances are reasonably matched to ensure stable operation of the circuit.
7. How to obtain the latest model comparison tableThe latest chip resistor screen printing model comparison table is generally released by resistor manufacturers, such as the official websites of Murata, Samsung, Yageo and other companies, or authoritative electronic component databases and industry standard documents. It is recommended to follow these channels regularly to obtain the latest information.
8. Future development trends of screen printing models of chip resistorsWith the trend of miniaturization of electronic components, silk screen models will be more simplified and standardized, combined with QR codes and digital management methods to improve identification efficiency and accuracy. At the same time, intelligent manufacturing and automatic identification technology will also promote the upgrade of model identification.
The screen-printed chip resistor model comparison table is an essential reference tool for electronic engineers and maintenance personnel. Through the introduction in this article, you should be able to master the latest model coding rules, common model comparisons and letter identification meanings, thereby improving work efficiency and accuracy. It is recommended to continuously update knowledge based on practical applications and manufacturer information to ensure that you remain competitive in the rapidly developing electronics field.
