With the rapid development of electronic components,Chip resistorAs a basic component in circuit design, its parameter identification and selection have become particularly important. patchresistanceInformation such as resistance, error, and power are usually marked by silk screen printing. However, due to the various marking methods and the complexity of digital codes, it brings a lot of trouble to engineers and technicians. This article will provide an in-depth introduction to the relevant content of "online query of chip resistor screen printing" to help readers quickly and accurately identify chip resistor parameters and improve work efficiency.
1. Basic concepts of chip resistor screen printingThe silk screen printing of chip resistors refers to the code printed on the surface of the resistor, usually composed of numbers and letters, to indicate the resistance, tolerance and other performance indicators of the resistor. The screen printing rules for chip resistors of different manufacturers and models are slightly different, but generally follow the internationally accepted coding standards. Understanding the basic rules of silk screen printing is a prerequisite for online inquiries.2. The importance of online inquiry for screen printing of chip resistors1. Improve identification efficiency: Traditional manual searches are time-consuming and laborious, but the online query platform can quickly locate resistance parameters.2. Reduce the risk of misjudgment: automatically analyze the silk screen code to avoid manual identification errors.
3. Support multiple brands and models: covering mainstream chip resistor brands to meet different needs.
4. Convenient engineering design: Quickly obtaining parameters helps circuit design and component replacement.
3. Analysis of mainstream chip resistor silk screen coding rules1. Three-digit code: Common in smaller resistance resistors, the first two digits represent significant figures, and the third digit represents the multiplier.2. Four-digit code: used for more accurate resistance value expression, the first three digits are valid, and the fourth digit is the multiplier.
3. Letter coding: Some resistors use letters to indicate the resistance range or error level.
4. Special symbols: Sometimes special symbols appear to indicate temperature coefficient or power level.
4. How to use the chip resistor screen printing online query platform1. Visit the professional inquiry website or APP.2. Enter the silk screen code or upload the resistor picture.
