New high power current sense resistors offer high measurement accuracy and low cost

The CSS series high power current sense resistors from Bourns come in both two-terminal and four-terminal options and can now be sourced in Europe through TTI Europe. The two-terminal models are available in three different footprint sizes: 5930, 3920 and 2512 (6332 Metric). With resistance values as low as 0.2mOhm, each family will offer a range of low resistance options and power ratings of up to 15W. The four-terminal design allows for high precision kelvin resistance measurements and is available in size 4026. Further technical details of CSS series components include excellent long-term stability, low inductance, low thermal EMF, and custom capability. AEC-Q200 compliant, the resistors have been designed for applications such as current sensing, battery management systems, power modules/motor controllers, as well as frequency converters Current sense resistors are increasing in popularity due to their high measurement accuracy and relatively low cost in comparison to other technologies. These resistors identify and convert current to an easily measured voltage which is proportionate to the current through the device.
