High power current sense resistors offer high measurement accuracy and low-cost

The Bourns Model CSS Series, available from TTI Europe, comes in both two-terminal and four-terminal options. The popular two-terminal models are offered in three different footprint sizes, 5930, 3920 and 2512 (6332 Metric). With resistance values as low as 0.2mOhm, each family will have a range of low resistance choices and power ratings of up to 15W. Current sense resistors are growing in popularity due to their high measurement accuracy and comparatively low cost related to other technologies. These resistors detect and convert current to an easily measured voltage which is proportionate to the current through the device. The resistor has an EB welded metal strip, with excellent long-term stability, low resistance, low TCR, and low thermal EMF.
