Comparison table of SMT resistor packaging dimensions, precise selection, and improvement of electronic component application efficiency

In the selection process of electronic components, the packaging size of SMT resistors is an important factor that cannot be ignored. Different sizes can affect the effectiveness of resistors and the design layout of circuit boards. This article will provide you with a detailed comparison table for the size of SMT resistor packaging, helping you accurately select the appropriate resistor and improve the application efficiency of electronic components

1、 Type and size of SMT resistor packaging

1 14mm pitch packaging

This type of packaging has a smaller size and is suitable for high-frequency and high-precision circuit applications. Common 14mm pitch packages include 0603, 0805, 1210, etc. Among them, the length of the 0603 package is 0.6mm and the width is 0.3mm; The length of the 0805 package is 0.8mm and the width is 0.5mm; The length of the 1210 package is 1.2mm and the width is 1.0mm

2 20mm pitch packaging

This type of packaging has a larger size and is suitable for low-frequency, high-power circuit applications. Common 20mm pitch packages include 0603, 0805, 1212, etc. Among them, the length of the 0603 package is 0.6mm and the width is 0.3mm; The length of the 0805 package is 0.8mm and the width is 0.5mm; The length of the 1212 package is 1.2mm and the width is 1.2mm

2、 Principles for selecting the size of SMT resistor packaging

1 Choose the appropriate packaging size based on circuit requirements

When selecting the packaging size of SMT resistors, it should be determined based on the actual needs of the circuit. For example, for high-frequency circuits, small-sized 14mm spacing packaging should be selected; For high-power circuits, large-sized 20mm pitch packages should be selected

2 Pay attention to the number and spacing of pins

When selecting the size of SMT resistor packaging, it is also necessary to consider the number of pins and spacing. Generally speaking, the more pins there are, the smaller the capacitance value; The smaller the pin spacing, the greater the capacitance value. Therefore, in practical applications, it is necessary to choose the appropriate number and spacing of pins based on the specific requirements of the circuit

3、 Summary

The comparison table of SMT resistor packaging dimensions is an important reference tool for electronic engineers in the selection process. By accurately grasping the characteristics and application scope of various packaging sizes, the efficiency of electronic components can be effectively improved, costs can be reduced, and the research and development cycle can be shortened.
