When it comes to chip resistors, most of them will pay attention to its resistance, power and so on. Will forget the accuracy. In fact, its accuracy is also very important.

Take smart home appliances as an example: the accuracy of chip resistors will directly affect the performance and effects of electrical equipment. The main reason is that the accuracy of resistors affects the ability to regulate current and voltage, and it has a great impact on smart home appliances. An important guarantee for product accuracy. After research, it is found that 0.5% precision chip resistors are very suitable for the application of smart home products. Of course, different electronic devices have different choices for the accuracy of chip resistors.

SMD resistor resistance error accuracy

Mainly have ±1%, ±2%, ±5%, ±10% accuracy.


J-indicates that the accuracy is 5%,

F-means that the accuracy is 1%.

T -means taping packaging


Small size and light weight; suitable for reflow soldering and wave soldering; stable electrical performance and high reliability; low assembly cost and matching with automatic placement equipment; high mechanical strength and superior high-frequency characteristics.


Resistance identification method of chip resistor

1. Add a letter after the 2 digits:

The first two digits of this method indicate the effective value of the resistance value, and the following letter indicates how many powers of 10 should be multiplied after the effective value, in Ω.

For example: 02C is 102×102=10.2kΩ, 27E is 187×104=1.87MΩ
