How Does Microhm High Precision Resistors Produced?

How Does Microhm High Precision Resistors Produced?

Precision resistor is a kind of resistor with low resistance error, good thermal stability, and the distribution parameters reach a certain standard. Because of the strict requirements of alloy materials smelting technology and related processes, high precision alloy materials, such as CuMn12Ni, are needed for precision resistors made by stamping with alloy materials. The precision of resistors produced by CuMn12Ni alloy material is less than 1%, and the precision resistance can be obtained by further adjusting the alloy shee...

What are the Main Aspects of the Resistor Protection to the Circuit?

What are the Main Aspects of the Resistor Protection to the Circuit?

In many circuits, we often encounter great harm caused by overvoltage, surge, overheating and so on. The latest circuit protection devices not only need to pay attention to volt-ampere characteristics, protection level and other factors, but also consider many other problems. As electronic devices are becoming increasingly thinner, smaller resistive components have to be developed to meet size limits so as to cover a smaller footprint. This requires manufacturers to continuously improve the energy density of resistance compon...

The Features of Metal Foil Resistor and Photoresistor

The Features of Metal Foil Resistor and Photoresistor

The metal film resistor is a widely used resistor so far, and plays an important role in the field of electronic industry and military space where require high precision. The metal film resistor is made of a special metal or alloy through a method of vacuum evaporation or sputtering to form a resistive film layer on the ceramic or glass. This kind of resistor is generally made by a vacuum evaporation process, that is, the alloy is heated in a vacuum, and the alloy is evaporated to form a layer of conductive metal film on the ...
