Resistors in Analytical Equipment And Instrumentation

Resistors 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...

Fixed Resistors' Safety Application Note

Fixed Resistors' Safety Application Note

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...

Thick-Film Technology Extends The Applications

Thick-Film Technology Extends The Applications

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 ...

Current Sense Resistors' Work Principle in Automotives

Current Sense Resistors' Work Principle in Automotives

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-Resistor Operation and How to Choose the Right One for Renewable Energy

Ammeter-Resistor Operation and How to Choose the Right One for Renewable Energy

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...

Resistors' Selection For Medical Applications

Resistors' Selection For Medical Applications

Passive components, like resistors, are hard to be chosen as the regulations and the unique characteristics of the healthcare environment. Since the human body is intrinsically analog, though, there will always be an important role for highly reliable passive components, like resistor, in systems including diagnostic, imaging, patient monitoring, instrumentation, and pharmaceutical delivery and dispensing applications. Approximately 20 passive components, resistor for example, are needed for each active IC in a design. AEDs p...

Power Resistor for Marine Application

Power Resistor for Marine Application

Power resistors, able to withstand and dissipate large amounts of power, have a wide range of applications within the marine sector. Choosing the correct components when building or refurbishing a ship is essential to ensure productivity and efficiency remain elevated. Resistors are required for many purposes including dynamic braking, ship stabilization and improving power quality using harmonic filters to protect delicate machinery on board. With so many applications for resistors, there are some important considerations to...
