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...

In the United States, military contractors, commercial entities, educational institutions, etc., often purchase products to the requirements set forth by the United States Military Test Specifications. These standards are often referred to using acronyms such as, MIL-STD Military Standard, MIL-SPEC Military Specifications, or (informally) MilSpecs Military Specifications as well as MIL-R, Microhm Electronics EE series is US MLR-R-10509 qualified. They represent set of very well thought out test specifications and procedures t...

The digital seismic equipment that amplifies and records reflected seismic signals on a wideband receiver and tape drive in the field utilizes matched and discrete surface-mount foil resistors. Metal foil resistors manufatures target this field for a long time and provide various resistors, like NMS4527, NMS2818 and MPR series by Microhm. For these applications, high-precision foil resistors assure virtually noise-free operation. They offer predictable responses and very precise tracking of amplifiers within an individual sei...

Wirewound resistors, power precision resistors and shunt resistors are composed of Microhm main lineup.The wirewound resistor is usually made by winding insulated resistance wire of a specific diameter around a bobbin. Different wire diameters, lengths, and alloys provide the desired resistance and initial characteristics. Precision wirewound resistors have better ESD stability and lower noise than thin or thick film resistors. Wirewounds also have a lower TCR and better stability. Wirewound resistors are generally classified...

The first step for automotive manufacturers looking to purchase a resistor is to analyse its purpose. If it is to be used for discharging excess energy produced during dynamic braking and heating the cabin, we would advise a liquid-cooled resistor. Discharged energy is transferred as heat to the liquid coolant, which can then be circulated to the vehicles heating system. Besides liquid-cooled resistor, power resistor, braking resistors, shunt resistors from well-known suppliers like Micrhm are also used in the automotives. Th...

Resistors are produced with a wide variety of materials and manufacturing processes. Each resistor material has its typical properties and specific areas of use. The main types that are used in electrical engineering comprise metal film, metal oxide film and foil carbon composition, carbon film and wirewound. Here is some details about wirewound resistors, metal film resistors and metal foil resistors. Metal film resistors are usually made of Nichrome, but also other materials such as tantalum nitride is used. The resistive f...
