Alloy Chip Resistor is a current sensing resistor. The main material is copper, and other materials are added to become constantan, manganin and so on. There are many other auxiliary materials, but the main performance is determined by the alloy itself. Next, I will tell you in detail "what is the alloy resistance, the characteristics and functions of the alloy resistance".
What are the characteristics of Alloy Chip Resistor?
What is the function of Alloy Chip Resistor?
What are the advantages of using Alloy Chip Resistor?
The material is alloy, the main material is copper, and other materials are added to form manganese copper, constantan, nickel copper and so on.
Low resistance value, the lowest resistance value can be 0.2mR~4R (determined according to the size), generally 2512, 1206, 2725, 2728, but with the continuous miniaturization and low power consumption of portable products And other requirements, alloy sampling resistors are also gradually miniaturized, such as 0805, 0603, 0402 and so on.
High power, the power is higher than ordinary resistors and power-up resistors, such as: the power of 1206 ordinary resistors is 1/4W, the power of 1206 liter-power resistors is 1/2W, and the power of 1206 alloy resistors is 1W/1.5 W.
Low temperature coefficient, TCR value ppm/℃. The temperature coefficients are 25ppm, 50ppm, 75ppm, 100ppm. The temperature coefficient of ordinary low resistance resistors is 100ppm/200ppm.
High precision, generally ordinary low resistance resistors are 5%, 1%, and alloy sampling resistors are 1%, 0.5%.
Anti-high current impact, due to its special alloy material, it has better resistance to high current impact characteristics, and the higher the power, the greater the current.
The effect of Alloy Chip Resistor on the current shunt;
Impedance matching;
Alloy Chip Resistor can divide the voltage in the circuit;
Filtering.
Each size of Alloy Chip Resistor has high power and high resistance value. At present, the main size 1206 ~ 4527 has the most specifications in the industry. The material is a pure metal plate, which is different from ceramics and ceramic laminated metal plates. The characteristics of pure metal plates are better than the former two. The power is sufficient, the alloy plate is thick, the service life is long, and it can withstand high surges. Alloy Chip Resistor is not only used in power supply products, but also has low EMF characteristics, and the dynamic EMF is small, which is suitable for battery modules. The EMF effect is low, and the current value can be measured more accurately when the load current changes sharply, and the system control is precise. High design ability, can be customized when necessary, various shapes, specifications and power.
