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 are the most basic passive component. It may seem like simple components with few applications, but resistors have a wide range of applications form factors and resistor types. Joule heating is the heat created as current passes through a resistor. Often this heat is an important factor in the selection of a resistor to ensure reliable operation, but in some applications, the purpose of the resistor is to generate heat. The heat is generated by the interaction with the electrons flowing through a conductor, impactin...

Thick-film resistors best suit the application of linearity , temperature coefficient (TCR), and long-term stability under voltage stress. Their temperature characteristic is typically U shaped with limits expressed by the TCR, normally from 25 to 100 ppm/C. The TCR error can be reduced by choosing the highest-possible ohmic value, which lowers self-heating, and by designing layouts that avoid proximity to heat-generating components. The temperature coefficient of thick-film resistors typically exhibits a classic U shape. To ...

Thick film chip resistor started to gain popularity in the 1970s. Today, these are by far the most used resistors in electrical and electronic devices. They come usually as chip resistor (SMD), and have the lowest cost compared to any other technology. The resistive material is a special paste with a mixture of a binder, a carrier, and the metal oxides to be deposited. The binder is a glassy frit and the carrier exists of organic solvent systems and plasticizers. Modern resistor pastes are based on oxides of ruthenium, iridiu...

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...

When the resistors are operated in ambient temperature above the rated temperature, the power rating must be derated according to the derating curve. Resistors in general may emit flame, fire, smoke or red heat when overload is applied. When a power exceeding the rated power is applied in a short time, we can not guarantee the safety only that the average power is below the rated power. Please contact Microhm with the surge voltage or current waveform for advise. Flame retardant resistors may emit smoke or cause red heat when...

Current sense resistors are recognized as cost-effective components that help improve system efficiency and reduce losses due to their high measurement accuracy compared to other technologies. Global trends such as the demand for lower CO2 emissions, the smartening of the electricity supply grid and the electrification of our automobiles are all driving the need for electronic circuits to become more efficient. For circuit designers and systems operators, understanding what level of current is flowing through a circuit and be...

Ammeter resistors are put back in the spotlight as the rise of renewable energy. The increase in the number of solar, wind, wave, and tidal power sources has pushed the need for a highly accurate method of measuring current. The solution is required for several reasons: to ensure accurate billing, have a more granular level of control, and, perhaps most importantly, to ensure the efficiency of the distributed power system. There are a few ways to measure current. However, the one most suited for renewable applications looks t...
