WAx Series Resistors

Isabellenhuette WAx series resistors are ideal for automotive and eMobility engineers looking to optimize performance, cycling stability, and durability

Image of Isabellenhuette WAx Series ResistorsIsabellenhuette WAT, WAF, and WAK series performance-driven resistors provide power and stability. They feature a dramatically better TCR than other solutions. These resistors have 25% higher power capacity at higher temperatures. All of this is welcome news for automotive and eMobility engineers looking to push their designs further while optimizing performance, cycling stability, and durability.

Features
  • Constant current up to 100 A (0.5 mΩ)
  • TCR: 0 ±50 ppm/K for maximum temperature stability
  • 5 W rated power at +135°C (0.5 mΩ)
  • Extra-large terminals for excellent power rating to optimize heat dissipation
  • Very robust during temperature cycles
Applications
  • High current applications for the automotive market (e.g., EPS, cooling fans, e-latches)
  • Current sensor for power hybrid applications
  • Frequency converters
  • Power modules
  • Motor controls in drones, e-bikes, and e-scooters
