PRECISION MEASUREMENT TECHNOLOGY
WAT (2512)
Roll cladded current sensing resistor

30% better TCR than comparable products
The latest addition to our performance-driven WAx series brings power and stability to the 2512 format. Dramatically better TCR than other solutions. 25% higher power capacity at higher temperature too. All of this is welcome news to automotive and eMobility engineers looking to push their designs further while optimizing for performance, cycling stability and durability.
Excellent Temperature Coefficient
TCR-curve of low resistance WAT-Z-L200 (200 μΩ) shows an excellent TCR of 0 ± 50 ppm/K.

Optimized heat dissipation
Large terminals: 3.05 x 2.75 mm; enough space for some thermal vias to optimize the heat dissipation.
