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...

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...

Precision current shunt is a kind of common resistor, which has been widely applied to household appliances. Precision current shunt has a wide variety of types and different models. They can be seen in many products. This resistor is widely used in both DC circuit boards and AC circuits, and can accurately test current size. In the precision current shunt, there are five very stable precision resistors ( 0.001, 0.01, 0.1, 1 and 10 ), which can be used to measure AC and DC currents from 0.02A to 220A. The principle of AC / D...

Metal strip chip resistors are the first choice in many circuit design applied surface mount resistors. Because of its particularity, alloy chip resistance can be widely used in many products, especially in the circuit design of electronic products. It is often used to detect voltage or current size. Resistance manufacturers usually use rectangular metal composite strips to make alloy chip resistors, which are safe and convenient for production and transportation. In the current sampling scheme, the current value can be fed ...
