Thin-film resistor technology and thick-film resistor technology are popular resistor production technologies in the market at present, and the use of these two resistance techniques can be seen on many resistors. When it comes to resistors, we have to think about the noise of resistors. In fact, all the resistors produce a certain amount of noise, it is only the size of the noise. In many cases, resistance noise can lead to fatal defects, many products have strict control requirements for resistance noise. The production tec...

Non-inductive resistor, only relatively speaking, is mainly to meet the needs of intermediate-frequency circuits and high-frequency circuits. The inductance of wire-wound resistance is reduced by selecting non-magnetic material and special winding method, which is close to ideal pure resistance. There are many relationships between noninductive resistor and wire-wound resistor. Many noninductive resistors are wire-wound ones. In the strict sense, wire-wound resistors are actually inductive resistors. There are usually severa...

Precision resistors are often used in high-precision electronic circuits. In fact, the precision resistors refers to the resistance error, the thermal stability (temperature coefficient) of the resistance, the distributed capacitance and the distributed inductance in the distribution parameters of the resistor, and so on. Precision resistors are indispensable in many high-end electronic devices without which they cannot perform properly. For instance, most of the military grade resistors use precision resistor products. Prec...

In the past year, the market of photovoltaic inverter mainly consists of centralized inverter and series inverter, and the proportion of micro-inverter and distributed inverter is small. With the rapid development of distributed photovoltaic market, the proportion of series inverters in centralized photovoltaic power stations is increasing, and in 2018, the market of series inverters accounts for 60.4%. In addition, it is worth noting that the distributed photovoltaic inverter improves the MPPT control effect compared with t...

The battery management system (BMS) is like the heart of a new energy vehicle, and many new energy vehicles lack the competitive power often reflected in the defects of the battery management system. For many new energy vehicle brands, it is very difficult to develop a battery management system. Because the battery management system contains many resistive components, such as precision resistors, shunts, capacitors, transistors, and so on. These products need professional brand suppliers, and technology is also critical. At p...

With the development of the electric vehicle, the charging pile of the electric vehicle has started to be extended and applied. For electric vehicles, the battery management system detects the battery through the precision shunt, and will prompt the owner to charge the charging pile when the battery is found to be insufficient. The frequent problem of charging piles is the phenomenon of electric leakage, which is very unsafe for both the charging pile and the electric vehicle. In order to provide better safety, the charging p...

A car grade resistor is an important electronic component of automobile electronic products. For many automotive resistors, it can be entered into the automobile market only when it meets the requirements of automobile electronics. Many automobile manufacturers have very strict requirements for resistors because this small resistor may affect the safety of the entire car. Car gauge resistors usually need to be certified by AEC-Q100 standard. The AEC-Q100 standard is designed to prevent possible situations or potential failur...

The shunt resistor is widely used in the digital watt-hour meter, high-precision test instrument, and all instruments and meters for measuring, sampling and shunting current, and can also be used as the main component of the current sensor. At present, the traditional shunt resistor is low in precision, and the temperature coefficient is high. It is difficult to meet the higher requirements, and many resistance manufacturers have started to develop new shunt resistors. The shunt resistor comprises a resistor composed of a co...
