Stackpole has revealed that its HCS high current SMD shunt resistors are now available in a 0.2mΩ resistance value in chip sizes of 3920 and 5930. The HCS has an all metal welded construction with a raised resistance element which provides more efficient thermal conduction, allowing the HCS to handle higher currents with lower self-heating compared to comparable flat chips.
The HCS3920 has a 5W power rating and the HCS5930 has a 10W power rating. The HCS is a popular choice for high power lighting controls, power supply and electric motor controls, robotics, electric power tools and automotive and industrial equipment controls.
Pricing for the HCS varies with size, resistance value and tolerance, ranging from $0.28 to $1.15 each in full reel quantities.
