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