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...

Resistors' Types and Characteristics

Resistors' Types and Characteristics

There are a lot of different resistor types, all with their own applications, characteristics and construction. Microhm Electronicss resistors are broadly ultilized in automotives, green engeries, communications and more. This page lists the different resistor types which are described on the resistor guide. Fixed resistors The fixed resistor type is the most common resistor, when people talk about a resistor they most probably mean a fixed resistor. Fixed resistors have a constant resistance value. Different resistor materia...

Cylindrical Resistors' Resistance Values and Tolerances Revealed By Banded Codes

Cylindrical Resistors' Resistance Values and Tolerances Revealed By Banded Codes

In the ever-shifting world of electronics, one thing that hasnt changed over the years is the resistor color code. It is used to identify resistance value and tolerances for cylindrical resistors with axial leads. The International Electronics Commission formally defines the color code in its IEC 60062 standard. Microhm Electronics HPMRY series and PMRY series are popular cylindrical resistors. The resistor color code is expressed in bands of various colors imposed sequentially across the circumference of the resistor. There ...

Microhm Electronics' Sense Resistor for Motor Control

Microhm Electronics' Sense Resistor for Motor Control

The use of current sense resistors, such as Microhm Electronics shunt resistors, is part of a trend in motor control system design that benefits from adopting new digital isolation technologies. These technologies offer higher reliability levels to designers based on the introduction of the component level standard IEC 60747-17, which specifies the performance, test, and certification requirements for capacitive and magnetically coupled isolators. Digital control of a motor drive incorporates current sense resistors for sensi...

High Power Precison Shunt Resistors Contain Integrated RTD

High Power Precison Shunt Resistors Contain Integrated RTD

Measuring high current in circuits such as DC power supplies requires shunt resistors. Unfortunately, those resistors affect the circuits performance because of the voltage drop needed to make the measurement in the first place. Plus, shunt resistors generate heat that needs to be managed. Microhm Electronics NSR series of metal-foil resistors contain an embedded Pt100 RTD sensor that you can connect to a temperature-measurement circuit or instrument to monitor the resistors temperature. The drawing below shows the voltage (V...

Film Resistors' Role in  Automotives' Signal Conditioning and Calibration

Film Resistors' Role in Automotives' Signal Conditioning and Calibration

In almost all new vehicles, an electronic engine control module teams with sensors and actuators to constitute the engine control system where film resistors play important roles. Piezoresistive transducers implanted in a silicon wafer with bulk micromachined diaphragms have become the dominant technology for producing automotive pressure sensors. Initially an absolute, bulk micromachined, piezoresistive pressure sensor element with a backside constraint for the formation of a vacuum reference cavity--a necessary element for ...

LHR Series Wirewound Resistors Work in Harsh Environment

LHR Series Wirewound Resistors Work in Harsh Environment

Microhm Electronics expandeds its line of high-power wirewound resistors with the new LHR series of rugged metal-clad braking resistors that target industrial and commercial applications such as motor drives, power conversion systems, HVAC systems, and battery charging and monitoring applications. The LHR series, encased in aluminum and offer a power rating of 300 watts. These rugged resistors provide excellent heat transfer and reduce the need for heatsinking. They are also significantly less sensitive to heatsink requiremen...

High Voltage Resistors For  Switched-Mode Power Supplies

High Voltage Resistors For Switched-Mode Power Supplies

There are a vast array of power supplies on the market, and the variety of resistor applications, such as high voltage resistors, anti-surge resistor, non-inductive resistors, in those designs broaden the selection dramatically. 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. The nomenclature of power supplies is often taken from whether the input is AC or DC, and what type of regulation is...
