In daily production, linear resistors can be used to simulate the high precision and low temperature drift characteristics of chip resistors, and the operating conditions of chip resistors are analyzed when voltage and current values are limited to rated conditions. This technique can also be applied to plug-in resistors. If the voltage or current value exceeds the specified value, the resistor will be overheated and will not comply with Ohms law, and will even be burned down. High precision low TCR chip resistor are designed...

Shunt resistor can be used in many electronic products. It consist of slot shunt and non-slot shunt. These two types of shunt are widely used in automotive electronic products, especially in battery management systems. In the case of Teslas new-energy electric vehicle, the use of precision dividers gives it a competitive advantage over other cars in the industry, which we would also call automotive grade resistors. In new energy automotive electronics, automotive shunt is usually made of Mn-Ni-Cu alloy resistance rod and copp...

Generally, Mn-Cu alloy is used for production of automotive shunt. Mn-Cu alloy has relatively small temperature coefficient of resistance (TCR), low thermal EMF against copper, excellent annual stability of resistance, good weldability and workability. We know that the resistance value will change with temperature. For automotive shunt, the change of resistance value directly affects the precision of measurement. For precision instrument, this effect is enough to constitute an error to the precision. The resistivity and stab...

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 charging pile is the nipple of the new energy vehicle, and the new energy vehicle cannot drive without the popularity of charging post. With the increasing use of new energy vehicles, many places are actively promoting the installation and use of charging piles. How to realize fast charging and reduce the failure rate of charging pile has become a difficult problem for many charging pile companies. At present, many DC charging piles on the market are designed with high precision resistors, and the fault rate of many charg...

Switching power supply products will be optimized in the design of many electronic products, excellent switching power supply can effectively protect electronic products from high voltage damage, and can effectively improve the service life of the products. Power resistors are often seen in switching power supply products, which are often used by designers to protect power products when designing switching power supplies. The linear power supply may be less efficient because of the energy consumption of transmission devices ...

The current sampling resistor is a kind of very common resistor. The current sampling resistor is usually in series in the circuit, but the voltage sampling of the current sampling resistance is parallel. Many brand sample resistors have plug-in resistors and chip resistors. Because the sampling resistance can truly reflect the current or voltage fluctuation, it requires high precision and is very susceptible to the influence of temperature. When sampling the current, the resistance value is very large and the partial voltag...

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 ...
