Microhm Achieved Great Success in electronica Shanghai, 2019

Microhm Achieved Great Success in electronica Shanghai, 2019

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...

Power Resistors' Features and Applications

Power Resistors' Features and Applications

Power resistors are designed to withstand and dissipate large amounts of power. In general they have apower ratingof at least 5 Watt. They are made from materials with a high thermal conductivity, allowing efficient cooling. They are often designed to be coupled with heat sinks to be able to dissipate the high amount of power. NLR series and MVR series from Microhm Electronics are very popular precision power resistors with heatsink, Nual series is a traditional metal-clad power resistor. Some might even need forced air or li...

Microhm Electronics Cement Resistor NWH Series

Microhm Electronics Cement Resistor NWH Series

Cement resistors, such as Microhm Electronics NWH series, are made by winding resistance wires around non-alkaline ceramic core or metal oxide film rod, which is added with a layer of heat and humidity resistant and non-corrosive protective material. If you are designing a circuit where a lot of current is being passed through a resistor and with it needing to be resistant to high heat and flame, cement resistors is a good design choice. Microhm Electronics offers cement resistor NWH series for customers power supply, current...

Tolerance and Measurement of Resistance at Low Values

Tolerance and Measurement of Resistance at Low Values

The ability to measure low values to tight tolerances is a concern to both the manufacturer and the user. Microhm Electronics low ohm resistors with tight tolerance covering shunt resistosrs, metal foil resistors, metal film resistors and more. The problem is compounded in the cases of high current shunts where the self-heating will cause the in-service resistance value to be different than that obtained with low current level measuring equipment. Therefore, the measurement conditions must be defined at the time of specificat...

4-Terminal Resistors Work Principle

4-Terminal Resistors Work Principle

In a 4-terminal resistor, an ultra-precise resistor (green) is connected to 4 terminals through small, but unknown, resistors (red). These unknown resistors are the combination of lead resistance, screw terminal resistance, connection wire resistance, and other sources of errors. Typical values for these unknown resistors range from 0.01 ohms to 0.2 ohms, and the values are often unstable. The values can change when you loosen or tighten a screw, for example, or if you substitute a longer test lead. To use a 4-terminal resist...

Resistors for Automotive

Resistors for Automotive

Ever-evolving automotive technology is no longer confined to the basic vehicle functions of propulsion, steering, and braking. It is now expanding into a variety of disciplines. Remarkable advances in automotive technology, most notably in areas such as telematics, advanced safety features, and environmental compatibility, have led to tremendous evolution in our vehicles and our automotive society since the days when vehicles were merely a means of getting around. This evolution has been facilitated by electronic components, ...

Resistors Used in Analytical Equipment and Instrumentation

Resistors Used in Analytical Equipment and Instrumentation

Precision resistors deliver the tight tolerances, low temperature sensitivity, and high stability demanded across a broad range of laboratory analysis equipment . The input stage of an instrument with a resistive sensor, such as a thermistor in a precision temperature-monitoring circuit, consists of a bridge of resistors, which must be closely matched in value. Since it is the ratio between values that matters rather than absolute values themselves, the maximum difference between TCRs (that is, the tracking TCR) is more impor...

Thin and Thick Film Resistors' Characteristics and Applications

Thin and Thick Film Resistors' Characteristics and Applications

Thin and thick film resistors are the most common types in the market. They are characterized by a resistive layer on a ceramic base. Although their appearance might be very similar, their properties and manufacturing process are very different. The naming originates from the different layer thicknesses. Thin film has a thickness in the order of 0.1 micrometer or smaller, while thick film is around thousands time thicker. However, the main difference is method the resistive film is applied onto the substrate. Thin film resist...

Selecting Right Resistors for Preamp, Amplifier and Other High-End Audio Applications

Selecting Right Resistors for Preamp, Amplifier and Other High-End Audio Applications

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. 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. Microhm Electronics manufactures varied resistors, including below mentioned thin film resistors, thick film resistors, ...
