Unprecedented increases in the price of ruthenium, a key element in the production of thick film pastes used in thick film chip resistors, has resulted in extended lead times for the ubiquitous resistor component. Because of the large percentage of variable costs in the production of chip resistors relying on raw materials, expect price increases and short supply for the rest of CY 2021 and FY 2022.

Stackpole releases HCSM2818 high current shunt chip resistors with a 5W power rating. Modern electronics utilize current sense resistors for portable power management. As more devices become portable, higher currents and higher power ratings are critical, however, space for any portable electrical device must always be conserved.

Voltage and Frequency Dependence on Resistors

Voltage Dependence If we apply a voltage on a resistor it’s resistance will drop slightly in certain types. Therefore the resistance change is negative. The change per volt of applied voltage is called voltage coefficient, VC, and is expressed in %/V or better, μV/V. The coefficient is determined not only by the resistive material but also by the dimensions, i.e., the electrical field strength, and the time of applied voltage. Thus, MIL-STD-202, Method 309 prescribes measurements when the voltage is applied intermittently for less than 0.5 seconds.
