What is alloy resistor What are the main application area of alloy resistor

Alloy resistor is a kind of ultra-low-resistance chip resistance with high precision and high power. The common resistance value is between 1mΩ~150mΩ, and the temperature coefficient is mostly 50ppm~100ppm. The common sizes are mainly 0805, 1206 and 2512. It is mainly used as sampling resistor, such as current detection of power circuit and engine circuit. At this time, the common ceramic-based chip resistor is difficult to realize from the process. Therefore, an alloy chip resistor is specially developed for high-power applications. In the structure, an alloy layer is used to replace the ceramic substrate of the common chip resistor. The whole structure comprises the following parts: an alloy layer, a copper layer, a nickel layer, a tin welding layer, a protective layer and a resistance value mark printed on the surface.

What are the main application area of alloy resistor ?

Alloy resistor is a resistor with alloy metal as current medium. It is generally characterized by low resistance value, high precision, low temperature coefficient, impact current and high power and so on. It is generally called precision alloy resistor. These resistors are commonly used in various electronic products and are mainly used in current sampling or short-circuit protection. Alloy resistor generally has low resistance value, such as 1mΩ, 10mΩ, 100mΩ, etc as the strong conductivity of metal. It is often used for sampling the current in a circuit for feeding back the varying current in the circuit to further control or influence the variation of the current. The main applied products are as follows of battery protection plate, power supply, BMS energy storage, frequency conversion industrial control, lamp lighting, motor starting current protection plate, etc.
