With the continuous development of electronic products,Chip resistorAs an indispensable part of electronic components, it has been widely used. 1210 package as SMDresistanceOne of the standard package sizes, it is widely used because of its moderate size and good performance. This article will introduce the chip resistor 1210 package size diagram in detail to help electronic engineers and purchasers better understand and select such components.
1. Overview of chip resistor 1210 packageThe chip resistor 1210 package refers to its size specification of 0.12 inches × 0.10 inches (ie 3.2 mm × 2.5 mm). This package size is medium in the electronics manufacturing industry and is suitable for circuit board design of various electronic devices. It not only ensures the stability of the components, but also facilitates automated mounting.
2. Standard size parameters of 1210 packageAccording to international electronic component standards, the specific size parameters of the 1210 package include:
Length: 3.2 mm (0.126 inches)
Width: 2.5 mm (0.098 inches)
Thickness: Typically 0.55mm to 0.65mm
Pad size: generally 1.0 mm × 1.3 mm, specifically adjusted according to PCB design requirements
These dimensions ensure that the chip resistors can be adapted to common automatic placement machines and reflow soldering processes.
3. Dimensional drawing of 1210 package1210 package dimensional drawings usually include front view, side view and pad layout diagram. The front view shows the length and width, the side view shows the thickness, and the pad layout diagram indicates the welding area and installation location, helping designers accurately arrange PCB pads and improve welding quality.
4. Size comparison between 1210 package and other packagesCommon chip resistor packages include 0603, 0805, 1206, etc. The 1210 package size is between 1206 and 1812. The specific comparison is as follows:
0603：1.6mm×0.8mm
0805：2.0mm×1.25mm
1206：3.2mm×1.6mm
1210：3.2mm×2.5mm
The 1210 is larger in size and suitable for applications with higher power or requiring a larger pad area.
5. Application advantages of 1210 package1210 package chip resistors are commonly used in power management, automotive electronics, industrial control and other fields because of their moderate size and ability to withstand large power loads. In addition, its larger pad area helps dissipate heat and improve component stability and life.
6. Precautions for 1210 packaging in PCB designWhen designing PCB, the pad size and spacing need to be reasonably designed according to the 1210 package size diagram to ensure welding quality. At the same time, consider thermal expansion and electrical performance to avoid welding defects or circuit failures caused by dimensional errors.
7. Dimension confirmation when purchasing chip resistor 1210 packageWhen purchasing, you should strictly check the 1210 package size drawing provided by the supplier to ensure that it meets the design requirements. There may be slight size differences between different manufacturers, which affects the placement accuracy and welding effect of the placement machine.
The 1210 chip resistor package occupies an important position in the electronics industry with its moderate size and excellent performance. By understanding the detailed dimensional drawings and related design points of the 1210 package, electronic engineers can more accurately conduct PCB layout and component selection, improving product reliability and production efficiency. Whether it is design or procurement, accurately grasping the 1210 package size information is the key to ensuring circuit quality.
