The advantage of SMT resistor
1. small volume light-weight
2. accommodate reflow soldering and wave soldering
3. electric nature stable high reliability
4. low cost fitting and effective matching
5. high mechanical strength and high frequency.
The method of labeling SMT resistor
SMT resistor’s resistance is similar to ordinary resistor. There are three methods to label.
1. use number to mark it(rectangle)
2. use color to mark it (cylindrical)
3. E96 code and letter
Five parameters of SMT
SMT is widely applied in electronic industry, more than 90% electronic products is made of SMT. Our country supply SMT at the beginning of 1980s. With the widely used of minitype SMT production equipment, the applied range of SMT is further expand to the field of aviation, spaceflight, instrument, machine tool and so on.
1. The type of SMT resistor has seven types.
2. Resistance value type, the confirmation of nominal resistance is according to the type.
3. Tolerance SMT resistor has four grades.
4. Temperature coefficient SMT resistor has two grades.
5. There are two major kinds of packing; they are Scattered and Ribbon Pac.
