With the continuous upgrading and miniaturization of electronic products,Chip resistorAs a basic component in electronic components, the standardization and diversification of its packaging size has become particularly important. Learn about the various patchesresistanceThe package size not only helps to design a reasonable circuit board layout, but also improves the performance and reliability of the product. This article will systematically introduce the common package sizes of chip resistors, and help engineers and electronics enthusiasts quickly master relevant knowledge through detailed charts and data.
1. The definition and significance of chip resistor package sizeChip resistor package size refers to the physical size of the resistor element housing, usually expressed in length and width. Common units are inches or millimeters. Clarifying the package size facilitates the automatic placement and soldering of components, as well as the rational design of circuit boards. Standardized sizes also ensure component interchangeability and supply chain stability.
2. Main chip resistor package size classificationThe common chip resistor packages currently on the market are mainly divided into the following categories:
0201(0.6mm×0.3mm)
0402(1.0mm×0.5mm)
0603(1.6mm×0.8mm)
0805(2.0mm×1.25mm)
1206(3.2mm×1.6mm)
1210(3.2mm×2.5mm)
1812(4.5mm×3.2mm)
These sizes cover application needs from ultra-small to medium to large.
3. Relationship between chip resistor size and powerThe larger the package size, the more power the chip resistor can typically carry. For example, the resistor power of the 0201 package is generally 1/20 watt, while the resistor power of the 1206 package can reach 1/4 watt or even higher. When designing, it is necessary to select the appropriate size according to the circuit power requirements to prevent component damage due to power overload.
4. Applicable scenarios for different package sizesUltra-small 0201 and 0402 are suitable for mobile devices, smart wearables, etc. with extremely limited space.
Medium-sized 0603 and 0805 are widely used in household appliances and communication equipment.
Large 1206 and above are suitable for industrial equipment with large power or high heat dissipation requirements.
Choosing the appropriate package size can effectively improve product performance and production efficiency.
5. Demonstration of complete table and diagram of chip resistor package dimensionsThe following is a table of typical chip resistor package dimensions (unit: mm):
| Dimensions | Length | Width | Typical power (W) ||----------|------|------|---------------|
| 0201 | 0.6 | 0.3 | 0.05 |
| 0402 | 1.0 | 0.5 | 0.063 |
| 0603 | 1.6 | 0.8 | 0.1 |
| 0805 | 2.0 | 1.25 | 0.125 |
| 1206 | 3.2 | 1.6 | 0.25 |
| 1210 | 3.2 | 2.5 | 0.5 |
| 1812 | 4.5 | 3.2 | 1.0 |
6. How to choose the appropriate chip resistor package sizeWhen selecting package size, the following points should be considered:
Board space limitations
Power load requirements
生产工艺和成本
产品的散热需求
综合评估后,选择既满足性能又便于生产的封装尺寸。
