It has a wide range of applications and simpler models. SMD resistor and plug-in resistor are the two most commonly used types. The following is an introduction to the differences between them:
1. Small size, light weight, easy to store and transport
Such as the commonly used SMD resistor 0805 package or 220, this package is smaller and longer than the plug-in resistance we used before. Dozens of plug-in resistor can fill a bag, but with SMD resistor, thousands or even tens of thousands can be filled. Of course, this has nothing to do with the maximum current it can withstand.
2. SMD resistor are easy to weld and decompose
Friends who have done it know that it is troublesome to disassemble the plug-in resistor. It is a PCB motherboard with more than two layers, even if it only has 2 pins, it is not very easy to replace and it is very easy to destroy the circuit board, multi-pin Not to mention that. The disassembly and assembly of the chip resistor is much easier, the other two pins are very easy to disassemble, and even the components of one or two hundred pins can be removed a few times without destroying the circuit board.
3. The resistance is stable and reliable
The stability of the SMD resistor is very good, which will greatly improve the stability and reliability of the circuit, reduce the production cost, and increase the productivity.
1. Large volume and large current withstand
The plug-in resistor has a smaller volume than the SMD resistor, but it can withstand a larger current. The plug-in resistor has a more stable performance than the SMD and is suitable for working in some harsh environments. Generally used for high-power product applications.
2. The solder is stable and not easy to replace
Need through holes, can be soldered with a large area, firmness, and good stability. Don't worry about replacing it during use, causing the circuit to be unstable on site.
