With the development of miniaturization and high performance of electronic products,Chip resistorAs a basic component in electronic components, it has been widely used. Among them, 0603 patchresistanceIt is popular for its compact size and stable performance. In the actual use and purchasing process, it is particularly important to understand the silk-screen resistance comparison table of 0603 chip resistors. This article will start with the basic concepts of 0603 chip resistors, introduce its silk screen resistance comparison table and related precautions in detail, and help electronic engineers and purchasers better identify and select this type of components.
1. Introduction to 0603 chip resistorThe size of the 0603 chip resistor is 0.06 inches × 0.03 inches (approximately 1.6mm × 0.8mm), which is one of the common chip resistor packaging specifications such as 0402, 0603, and 0805. Resistors of this specification are widely used in electronic equipment such as mobile phones, notebooks, and home appliances. They have the advantages of small size, convenient welding, and stable electrical performance.
2. The importance of silk screen resistance markingDue to the small size of the 0603 chip resistor, it is unrealistic to directly mark the resistance value on the component with numbers. Silk screen codes are usually used to represent the resistance value. Mastering the screen-printed resistance value comparison table can help engineers quickly identify resistor values and avoid selection errors or assembly errors.
3. 0603 chip resistor silk screen resistance coding rulesCommon silk screen codes use three-digit representation: the first two digits represent significant digits, and the third digit represents multiplied by a power of 10. For example, "103" represents 10×10³=10kΩ; "472" represents 47×10²=4.7kΩ; "000" represents 0Ω (zero ohm resistance). In addition, some resistors with smaller resistances will use "R" instead of the decimal point, such as "4R7" indicating 4.7Ω.
4. Common resistance value screen printing comparison tableThe following are examples of some commonly used 0603 chip resistors screen printing resistance values:
| Silk screen code | Resistance value ||----------|------------|
| 000 | 0Ω (zero ohm) |
| 100 | 10Ω |
| 220 | 22Ω |
| 472 | 4.7kΩ |
| 103 | 10kΩ |
| 154 | 150kΩ |
| 225 | 2.2MΩ |
5. Silk screen identification skillsNote that the "R" in the number represents the decimal point to avoid misreading.
Understand the common resistance ranges and quickly determine the actual resistance represented by the silk screen.
For special resistance values or non-standard coding, please refer to the detailed data sheet provided by the manufacturer.
6. Tolerance and power marking of 0603 chip resistorsSilk screen printing usually does not indicate resistance tolerance and power information, and it needs to be checked through the product specification sheet. Common tolerances include ±1%, ±5%, etc., and the power is generally 1/10W to 1/8W. The selection should match the appropriate tolerance and power level based on circuit requirements.
7. Procurement and storage considerationsConfirm that the silk screen resistance value is consistent with the design requirements to avoid product defects caused by misjudgment of the resistance value.
0603 resistors are small and easy to confuse. It is recommended to choose well-known brands and formal channels when purchasing.
The storage environment should be dry and anti-static to avoid affecting the resistance performance.
As a key component in electronic design, the correct identification of 0603 chip resistors directly affects the performance and reliability of the product. By mastering the silk screen coding rules and common resistance value comparison tables, engineers can select appropriate resistor models efficiently and accurately. At the same time, comprehensive consideration is given to tolerance, power and other parameters to ensure the smooth progress of circuit design and production assembly. I hope this article will help you understand the silk screen resistance value of 0603 chip resistors and improve the efficiency of electronic component selection.
