KOA Expands Shunt Portfolio

With the new current sense resistors of the PSJ2 and PSG4 series, KOA is expanding its range of metal plate power shunts. The four-terminal construction of the PSG4 with welded copper terminals allows high currents of up to 140 A in the 2725 inch size. These low-resistance, non-inductive power resistors are available in resistance values of 0.5 and 1 mΩ in the 2725 size and, as of mid-2017, also in 1216. Thanks to four-terminal technology, temperature coefficients of less than 50 ppm/K and long-term stable behavior during temperature fluctuations are achieved. AEC-Q200 test data are available.

The PSJ2 series is suitable for current measurements up to 244 A (200 µΩ). The resistors with welded copper terminals allow power ratings from 6 W to 12 W. These low-resistance, non-inductive power resistors are available in resistance values from 0.2 to 2 mΩ in the 3920 (PSJ2) size and, as of mid-2017, also in 2512 (PSL2). AEC-Q200 test data are available and allow for use in numerous automotive and industrial applications within an operating temperature range of -65 to +175 °C.
