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...

Increasing customers are looking for non-inductive resistors for their application, like power amplifier. Microhm Electronics provides various non-inductive resistors, such as NTW series, TWC series. Then what is resistor inductance? Lets figure it out. Inductance is an electrical property of conductors by which an electrical current passing through the conductor induces an electromotive force in the conductor itself (self-inductance) and other conductors nearby. Since resistors are made of conductive materials, they, too, ex...

After value, power dissipation is the next most important characteristic of a resistor. An overloaded resistor often changes in value over time and can often get hot enough to burn itself and surrounding components. Every circuit designer learns the smell of burnt resistor sooner or later! The common rule of thumb is to calculate how much power the resistor will have to dissipate and then use the next largest size or a factor of two higher dissipation rating, whichever is larger. The power rating is based on unobstructed air ...

High voltage resistors, like NUB series, are used in a wide range of applications including Power supplies, ESD protection, Electron Microscope, Air Ionising equipment, RADAR equipment and ATE. One of the main application of high voltage resistor dividers is in power supplies with a feedback loop for regulation purposes. Appropriate choice of resistor values and their ratio determines the feedback voltage. For optimal performance a primary high voltage resistor is often combined with a secondary low voltage resistor. To prev...

Current sensing is a critical function in electronic systems but comes with complexities that are often underestimated. Accurately measuring current flow is not nearly as easy as measuring voltage and is even more difficult when trying to measure the current flowing through a load connected to relatively high-power supply voltages. Current sense resistors, also called shunt resistors, like Microhm Electronics MPR series, MVR series, MMS series are the technology of choice for measuring current flow due to their high measureme...

Strain gages are fundamental sensing devices that function as the building blocks of many other types of transducersincluding pressure, load, and torque sensorsused extensively in structural test and monitoring applications. An example of such a transducer is a load cell that converts a mechanical force to an electrical output signal. In these designs, gages are connected as a Wheatstone bridge, resulting in an accurate and rugged transducer that can operate in extreme environments. To achieve accuracy, the Wheatstone bridge ...

There are a vast array of power supplies on the market, and the variety of resistor applications in those designs broaden the selection dramatically. So, for the purpose of this article, power supplies will be referred to as devices that have fixed DC outputs up to several kV. Whatever the application, power supply designers must be aware of specific regulations on safety or the environment that apply to the area, as well as the actual electrical performance. Resistors play an important role in regulating the supply output an...

Film resistor consist of Metal Film, Carbon Film and Metal Oxide Film resistor types, which are generally made by depositing pure metals, such as nickel, or an oxide film, such as tin-oxide, onto an insulating ceramic rod or substrate. The resistive value of the resistor is controlled by increasing the desired thickness of the deposited film giving them the names of either thick-film resistors or thin-film resistors. Metal Film Resistors have much better temperature stability than their carbon equivalents, lower noise and are...

Noise is an unwanted wide spectrum signal that may be superimposed on any useful signal, including DC. Resistors, like other passive components, are noise sources to various degrees, depending upon resistance value, temperature, applied voltage, and resistor type. In high-end audio equipment, careful selection of resistors is one of the best ways to avoid or minimize noise and distortion in the signal path. Many experiments have been done to show why some resistors are noisier than others. But the only test that audio experts...
