electronica China, lasting for three days, ringed down the curtain on Mar.22,2019 successfully. Microhm prepared elaborately and exhibited full range of resistors in the site. Customers from all over the world visited Microhm E5 - 5606, consulted resistors and experienced. Our staffs introductions of the features, applications and merits were brief and to the point. Customers not only stayed for a time in front of the reception to learn more about products, but also streamed into Microhms booth to have a close look of the mat...

Chip resistors mainly refers to thick film resistor, thin film resistor and metal foil resistor. The first two are traditional and most popular ones. Recent years, metal foil resistors are become popular for its higher precision, lower TCR, and lower inductance as it ismanufactured by alloy resistor materials, including constantan, manganin and more. The size of them can be as small to 0603. The chip resistor is inevitably damaged during the application process. The reasons might be misoperation, service condition or brand. T...

Surface mount resistors are also known as chip resistors usually with tiny black rectangles. The surface mount resistors have smaller edges on both ends and a glossy silver conductive edge. These surface mount resistors are located on top of the PCB where the surface mount resistors are soldered to the mating landing pads. Since these resistors are very small, they are usually placed in place by the robot and melted by solder and held in place. SMD surface mount resistors are available in standard sizes. These SMD resistors a...

The rated power of a resistor is the rate at which energy is converted into something. It is calculated by multiplying the voltage difference between two points by the current between them. The rated power of the resistor is measured in watts W. For example, a light bulb converts electricity into light, but a resistor can only convert electrical energy that passes through it into heat. Heat is usually not the energy required for a resistor product. If the resistor is too hot, it can easily lead to burnout of the circuit and e...

Automotive electronic system is a very large system, which contains a variety of resistors and other components. In these circuits, automotive resistors are very important, and some high-precision automotive resistors have different applications. In the automobile maintenance skill, it is usually found that the engine power is insufficient and the cause of the poor acceleration is generally the automobile resistance fault. At this time, it is necessary to analyze and detect the automobile resistance, and when measuring the re...

Precision shunts are generally produced using copper-manganese alloy materials. Many precision shunts developed by resistor manufacturers on the market generally use copper-manganese alloy or constantan alloy. These two types of precision shunts are widely used and applied. The shunt can guarantee 0.1% sampling accuracy within the range of 10%-100% of rated current. The special structural design effectively reduces the thermoelectric potential error and connection error, and 100% calibration is achieved before leaving the fac...

Thin film resistor is a kind of more common resistor. Usually the manufacturing method of thin film resistor includes insulating substrate, forming a conductor pattern layer on the insulating substrate by non-photolithography. A thin film resistance layer is formed on the conductor pattern layer and the insulating substrate. The thin film resistive layer is patterned by photolithography. This thin film resistor manufacturing method can reduce the manufacturing cost of thin film resistor, but at present, many thin film resisto...

Power resistance is a common resistor. In many cases, the volume of power resistance is closely related to power, and the larger the power, the larger the volume. But not all power resistors are like this. Power resistors are made of different materials or processes, and can not be judged by volume. For example, the same volume of metal film resistance and carbon film resistance, the former is more than twice the power of the latter. In addition, the resistance value of the power resistance is not directly related to the powe...

DC shunt is suitable for measuring DC current, directly acting on analog display instrument below 10KA. DC shunt is a kind of external shunt which is suitable for measuring DC current and directly acting on analog display instrument below 10KA. In addition, DC shunt is used to expand the measuring range of DC current. It can also be seen as standard resistors for current sampling in sequential circuits. The sampling voltage of the DC shunt can be regarded as the analog signal of the primary current used in the measurement. In...
