With the development of miniaturization of electronic products,Chip resistorAs basic electronic components, they play an important role in circuit design. 1210 patchresistanceBecause of its moderate size and strong current carrying capacity, it is widely used in various electronic devices. Understanding the 1210 resistor dimensions is critical to the design and purchasing process. This article will introduce in detail the size and specification comparison table of chip 1210 resistors to help engineers and purchasers make better selection and use.
1. Basic size definition of chip 1210 resistorThe "1210" of the 1210 resistor means that its size is 0.12 inches × 0.10 inches, which is approximately 3.2mm × 2.5mm when converted to metric units. This size refers to the length and width of the resistor body, excluding the leads. Understanding this will help you lay out components properly when designing a circuit board.
2. Thickness specification of 1210 resistorIn addition to length and width, the thickness of 1210 resistors typically ranges from 0.55mm to 0.75mm. There may be slight differences between different manufacturers and models, but generally it will not exceed 1mm. Thickness affects the heat dissipation ability and mechanical strength of the resistor and is a parameter that needs to be considered during design.
3. Relationship between resistor power and sizeCommon power ratings for 1210 chip resistors are 0.5W to 1W, which is higher than the smaller size 0805 or 0603 resistors. The larger size provides better heat dissipation conditions, making it suitable for applications carrying larger power.
4. Pin size and spacing of 1210 resistorThe pad size of the 1210 resistor is generally 1.8mm×3.2mm, and the pin spacing is about 2.5mm. Reasonable pad design contributes to welding quality and electrical performance, and avoids false soldering or short circuits.
5. Nominal resistance range of 1210 resistorChip 1210 resistors are available in a wide range of resistance values, from a few ohms to several megohms, to meet various circuit needs. The standard resistance accuracy is usually ±1% or ±5%, and the accuracy of high-precision models can reach ±0.1%.
6. Temperature coefficient of 1210 resistorTemperature coefficient is an important indicator to evaluate the stability of resistance as temperature changes. The common temperature coefficient of 1210 resistors is between ±100ppm/℃ and ±200ppm/℃, which is suitable for general industrial and consumer electronic products.
7. Material and packaging type of 1210 resistor1210 resistors are generally made using thick film or thin film technology.thick film resistorThe cost is low and suitable for high-volume applications; the thin film resistor has stable performance and is suitable for high-precision requirements. The packages are mostly rectangular and have a non-polar design to facilitate automatic mounting.
8. Application scenarios of 1210 resistorDue to its moderate size and high power carrying capacity, 1210 resistors are commonly used in power modules, automotive electronics, industrial control and other fields. Reasonable selection of size specifications will help improve product performance and reliability.
The SMD 1210 resistor size specification comparison table provides key size parameters and performance indicators and is an important reference for electronic design and procurement. Understanding its length, width, thickness, pad size, power level and performance parameters can help engineers make reasonable selections and improve the efficiency and stability of circuit design. With the continuous upgrading of electronic products, the rational use of 1210 chip resistors will provide a solid guarantee for the performance optimization of electronic equipment.
