Resistors, passive devices made using different materials, are electrical components that help control the flow of current in a circuit and applicable to a broad range of applications, including FA and robot. In the industrial world, especially in the field of FA, the integration with IT such as Industry 4.0 and Industrial-Internet and the use of big data are attracting attention. In particular, there are an increasing number of cases where high precision resistors are used for signal processing of many sensors of IoT. In add...

A shunt resistor is used to measure electric current, alternating or direct. This is done by measuring the voltage drop across the resistor. Several parameters are important to specify a shunt resistor. Shunt resistors have a maximum current rating. The resistance value is given by the voltage drop at the maximum current rating. For example, a shunt resistor rated with 100A and 50mV has a resistance of 50 / 100 = 0.5 mOhm. The voltage drop at maximum current is typically rated 50, 75 or 100 mV. Microhm milliohm shunt resistor...

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...

Resistors, as passive components, are widely used in all the applications consuming electricity including newly rising drones. From 2019 to 2023, the utilization of global drones will grow at a compound annual growth rate (CAGR) of 13.61%. Drones applications includes access to dangerous or remote areas, aerial photography and video, surveying, wildlife and forest fire records, rescue missions, agriculture military surveillance as well as civilian field. Because drones have low operating or low cost, no casualties, good maneu...

An ammeter shunt allows the measurement of current values too large to be directly measured by a particular ammeter. In this case, a separate shunt, a resistor of very low but accurately known resistance, is placed in parallel with a voltmeter, so that all of the current to be measured will flow through the shunt. The resistance is chosen so that the resultant voltage drop is measurable, but low enough not to disrupt the circuit. The voltage across the shunt is proportional to the current flowing through it, and so the measur...

Microhm has comprehensive marine experience, and supplied water and air-cooled break and submerged load resistors. Microhm products are designed to withstand adverse marine conditions. For large-scale wind farms where varying wind speeds effect the quality of power an SVC can be fitted to regulate transmission voltage. The SVC can also improve availability by reducing the impact of power fluctuations. Despite being less common than wind or solar power, wave and tidal power has a number of benefits. It is considerably more pr...
