What is the difference between SMD resistors and plug-in resistors?
What is the difference between SMD resistors and plug-in resistors? First of all, SMD resistors, also known as chip resistors, are a form of metal glass uranium resistors. Its resistance is made by high-temperature sintering with high reliability. . It is widely used in computer peripherals and power supplies, household appliances, lighting, battery packs, power supplies, etc. It can be said that as long as it is an electronic device with power, SMD resistors will appear.
Secondly, plug-in resistors, commonly known as resistors in daily life, are a current limiting component. It means that after the resistor is connected in the product circuit, the resistance value of the resistor is fixed, usually with two pins, which can limit the current of the branch connected to it. This common type of plug-in resistor includes varistors, thermistors, photoresistors, hygroresistors, etc. It is generally used in consumer electronics, computers, telecommunications and other fields.
SMD resistors
1. SMD resistors.
(1) Small size, light weight, easy to store and transport.
The commonly used SMD resistor package is much smaller than the plug-in resistor. Without considering the circuit current, the storage space of dozens of plug-in resistors can accommodate thousands to tens of thousands of SMD resistors, which greatly saves space in circuit design and greatly improves the operability of other aspects of the product.
(2) SMD resistors are easy to solder and disassemble.
SMD resistors do not require vias, have less tin, and are easy to disassemble. Even if one or two hundred pin components are disassembled several times, the circuit board will not be damaged.
(3) Strong stability and high reliability.
SMD resistors have good stability, which greatly improves the stability and reliability of the circuit and reduces production costs and productivity.
2. Plug-in resistors.
(1) Large size and large current.
Compared with SMD resistors, plug-in resistors are large in size but can withstand large currents. The performance of plug-in resistors is more stable than that of SMD resistors and is suitable for working in some harsh environments. It is generally used in high-power product applications.
The solder is stable and not easy to fall off.
The soldering area is large and the stability is good. There is no need to worry about falling off during use, causing circuit instability.
