We can often see the appearance of resistance products in our daily life. There are usually carbon film resistors, metal film resistors, metal oxide film resistors, etc. Currently, there are more and more alloy resistors on the market, and many people are not sure which materials are usually made of alloy resistors. The difference in resistance products made of different alloy materials is very large. Lets analyze the alloy resistance materials. 1. Copper-manganese alloy resistors produced from copper-manganese alloy material...

Precision shunts are widely used in the BMS of power battery management systems, and precision shunts are used in almost every power train. Precision shunts are used for current sampling in battery management systems. As power battery shipments continue to rise, precision shunts are also welcoming market opportunities. According to relevant data, in November 2018, Chinas new energy vehicle power battery installed capacity was about 8.91GWh, an increase of 50.22% from the previous month, an increase of 28.53%; the cumulative i...

The resistors have their own certain power. In many circuits, the power of the resistor must be determined and applied. Braking resistors are a very important resistor in the inverter circuit, and its power usage is also critical. If the braking resistor power is not used accurately, it will affect the efficiency of the entire inverter. Engineers often use the derating principle when using braking resistors, that is, the nominal power of the resistor will be less than the power consumed during power-on. The braking resistor w...

Alloy resistance is a resistor made of a metal alloy material, which has a strong electrical conductivity and is often used for sampling current in a circuit. Due to the particularity of the materials produced, the alloy resistance has the advantages of low resistance, high precision, low temperature coefficient, withstand current and high power. Many projects use alloy resistance when they are tested for pressure resistance. Then the resistance of alloy resistance is felt by those aspects. The withstand voltage of the alloy ...

Wirewound resistors are one of the most common resistors, and many engineers prefer to use wirewound resistors when using resistors. Generally, a wire is used for a wire-wound resistor. Usually, a wire made of an alloy material such as nickel-chromium or manganese-copper is used, and then a wire-wound resistor is formed around the insulating frame. The wire is wound according to different requirements. Or by winding multiple layers, it will also be produced by a non-inductive winding method. Many engineers like to use wirewou...

The materials used to produce the resistors vary in performance. People looking for resistance products often confuse metal film resistance with metal oxide film resistance. Although they differ by only two words in the text, they are quite different. Today we will analyze the difference between the metal film resistance and the metal oxide film resistance. We know that the metal film resistor is made of special metal or alloy as the resistance material. It has excellent pulse overload characteristics and mechanical propertie...

The frequency converter is an important part of the automobile. It controls the power control equipment of the AC motor by changing the frequency of the working power of the motor. The inverter is not limited to the application of automotive products, and the use of the inverter can also be seen on many other products. The frequency converter usually brings some problems during the use. The appearance of the brake resistor allows the inverter to successfully solve these problems. Below we will carefully analyze the use of the...

The resistor has four functions, namely voltage divider, shunt, impedance matching and filtering. There are many types of resistors. We usually have fixed resistors, variable resistors, special resistors, RT-type carbon film resistors, RJ-type metal film resistors, RX-type wirewound resistors, chip resistors, high-power resistors, and low-power resistors. So how many types of resistors are used in our production? First, the resistor has a shunt function and is often used in a variety of circuits for the distribution of curren...
