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 that tolerate against surge are used in power supplies, automotive, industrial equipment, consumer and power supply. Pulse means the overload of large power and with long duration(large energy) whereas surge means overload like ESD, of high voltage and with short duration. Anti-pulse resistors are unlikely to be damaged even if large power is instantaneously applied. Among SMD type resistors, thick film chip resistors, like compact Microhm NBS Series, are generally stronger against pulse than metal film chip resisto...

Lead has long been recognized as a serious environmental hazard. The Restriction of Hazardous Substances Directive 2002/95/EC (RoHS) legislated to remove metallic lead from electronic components. It should be noted though that there are certain exemptions to the RoHS directive where, at the time of its implementation, no viable substitute could be found. Among the areas where an exemption would prove to be warranted was in thick-film resistors, and to this day the incorporation of lead oxide compounds into their glass element...

Microhm Electronics announced the launch of E-Beam Welded Shunt resistor MMS8518 for industrial and automotive applications. MMS8518 is an electron beam welded resistance element, alloy material, typically MuCu, sandwiched between large copper terminals with optional tin plating. The low measurement error of this resistor frees up the designers error budget and its low ohmic values reduces power loss. The shunt MMS8518 provides the fullest selection of values ranging from 50 to 100Ω. Precision applications can make use of i...

Although not a complex component, resistors have specifications that can be confusing, misleading, and misinterpreted. When specifying performance qualities, it is important to review and understand the resistor test conditions to properly interpret and apply the results to your design. There are potentially significant differences in data presented by resistor manufacturers and those differences can significantly affect performance. The specification process for resistors involves more than just allowing for tolerance bands....

Full-metal shunt resistors consist of a homogeneous resistive element so that no additional inductance develops. This quality is key in such high-precision applications as medical technology or precision measurement devices. Furthermore, these resistors are characterized by high measurement accuracy and resistance to thermal shock. They are available in various sizes including versions that are much larger than standard chip resistors and TCR below 100 ppm/K. Full-metal resistors can operate with an output of up to 36W at max...

Today, practically every control and monitoring circuit uses shunt-based current measurements as an alternative to sensors. To make these measurements accurately, it is useful to understand how shunts work. Because the method is categorized as a precision measuring technology, Microhm reminds that it should be managed seriously. A shunt is a low-value resistor used to measure current it is therefore also referred to as a current-sense resistor. The shunt typically connects in series so it carries the current of interest. A vo...

Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system. The change in resistance then limits the current through the motor, which dictates the speed at which the blower fan works. Blower resistors, being a mechanical component, are prone to wear and are the most common point of failure in a cars heating system. This article...
