WAT – Power resistor for high current applications

The WAT from Isabellenhütte is the ideal solution for engineers who have the highest demands on precision and current carrying capacity. Specially developed for applications in automotive technology, power electronics and e-mobility - e.g. EPS, cooling fans, frequency converters, e-bikes and drones.

Highlights: 
  • Constant current up to 100 A (0.5 mΩ)
  • TC: 0 ± 50 ppm/K - for maximum temperature stability
  • 5 W rated power at 135 °C (0.5 mΩ)
  • Excellent cycle stability at changing temperatures
  • Excellent cycle stability at changing temperatures

Developed with proven Isabellenhütten alloys for maximum precision, long-term stability and robustness.

Optimized heat dissipation

Large terminals: 3.05 x 2.75 mm; enough space for some thermal vias to optimize the heat dissipation. Wide copper areas, short distances, and thermal vias reduce hot spots and keep drift low.
