Resistors
Shunt-based current sensors
It must be possible to measure currents accurately and reliably, even in large applications. The manufacturer RESI offers appropriate system solutions for this purpose.
Based on the latest shunt technology, sensors are offered that have various communication options.
Shunt Resistors from Resi
Current measuring resistors, or shunts for short, are used to measure the current in a circuit. By measuring the voltage drop that occurs when the current flows through the known resistor, the current can be calculated using Ohm's law (I = U / R).
In general, the resistance of the current measuring resistor is very small, between 1m Ω and 1 Ω, with a narrow tolerance and low TCR, as the ohmic losses should be minimised.
New pulse-resistant high-temperature SMD resistor
With the HSG73P series, KOA is offering an SMD resistor for the first time that combines pulse resistance and high-temperature properties. The resistors are available in SMD designs 0402 to 1206 and allow ambient temperatures of up to +200°C. The rated power is 0.2 W in the 0402 and 0.75 W in the 1206.
The components have very good pulse stability and ...

High-power resistors from Nikkohm
To provide designers with highly reliable power resistors that operate with the lowest temperature rise on the market, Nikkohm has introduced the RPU800 series (800 Watt) for inverter applications and is available in additional power classes (1000 W & 2000 W).
These unique high power resistors use Nikkohm's proprietary thick film and thin film technology on aluminium oxide substrate and offer up to 10kV insulation at low inductance.
