Current sense resistors come in 2- and 4-terminal options
The CSS series high power current sense resistors from Bourns that come in both 2-terminal and 4-terminal options can now be sourced in Europe through TTI. The 2-terminal models are available in three different footprint sizes: 5930, 3920 and 2512 (6332 Metric). With resistance values as low as 0.2mΩ, each family will have a range of low resistance options and power ratings of up to 15W.
The 4-terminal design allows for high precision 4 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 growing in popularity due to their high measurement accuracy and relatively low cost compared to other technologies.
These resistors detect and convert current to an easily measured voltage which is proportional to the current through the device.
