Stackpole’s CSS0508 is a one watt current sense chip resistor that combines high power in a small package, low resistance values, and low TCR in a robust all metal technology. In addition, the 0508 long side termination allows the part to run cooler under full rated power than similar size chips because the larger terminations are far more thermally efficient.
The CSS0508 is available in values of 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, and 5 milliohm, in tolerances as low as one percent and 100 to 150ppm TCR depending on resistance value. The CSS0508 is AEC compliant, RoHS compliant, as well as lead-free and halogen-free. Applications include power management, power modules, battery charging, frequency converters, hybrid power current sensing, engine and motor controls, and PC graphics and motherboards.
Pricing will CSS0508 in a one percent tolerance is around $0.115 each.
