Current sense resistors are fully AEC-Q200 compliant
Now available in Europe through TTI are CSS series high power current sense resistors from Bourns. The devices come in both 2-terminal and 4-terminal versions. 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 designs allow for high precision 4kelvin resistance measurements and are available in size 4026.
CSS series products benefit from excellent long term stability, low inductance, low thermal EMF, and are fully AEC-Q200 compliant. Custom versions are available upon request.
The main target applications are current sensing, battery management systems, power modules/motor controllers, as well as frequency converters.
Generally, 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.
