The integration of electronic circuits is developing rapidly, and the miniaturization of electronic components has become a new trend. The era created heroes, and chip resistors came into being.
Chip resistors have the advantages of small size, light weight, strong shock resistance, strong anti-interference ability, and good high-frequency characteristics.
How is the resistance value of the chip resistor identified? It is usually represented by numbers or numbers and letters.
The digital identification has three digits and four digits. The last digit represents the power of ten, the first few digits represent the effective value, and its resistance is equal to the power of the effective number multiplied by 10.
Three digits such as 243, three represent the third power of ten, 2 and 4 represent the effective digit 24, and the resistance value is equal to the third power of 24×10, which is equal to twenty-four thousand ohms.
Four digits such as 1243, three means the power of the third power, 124 means the effective number 124, Which is equal to the third power of 124×10, and the resistance value is equal to 124 kiloohms.
The decimal place is usually represented by R.
For example, 0.15, use R15.
For example, 1.5, use 1R5.
The above is the little knowledge of Tieba resistor identification.
