Bourns High Power Current Sense Resistor Families

The Bourns® Model CSS Series comes in both 2-terminal (2512; 3920; 5930) and 4-terminal (4026) options. The popular 2-terminal models are available in three different footprint sizes, 5930, 3920 and 2512 (6332 Metric). With resistance values as low as 0.2 mΩ, each family will have a range of low resistance options and power ratings of up to 15 W. 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. The 4-terminal designs allow for high precision 4 kelvin resistance measurements and is available in size 4026.
