What Our Customer Said ?

Ordered 500pcs of the 200W aluminum-clad resistors for our CNC drives. Despite a tight 10-day deadline, they delivered flawlessly. Zero failures after 6 months of 24/7 operation – the IP67 rating actually works!
John Doe
Lead Engineer
These 0.5mΩ current sense resistors have been a game-changer for our motor controllers. With ±10ppm TCR and AEC-Q200 compliance, we finally eliminated signal drift issues in high-vibration environments. The team even provided thermal simulation reports upfront – truly a partner
Maria S
Procurement Manager
We had resistor failures in our HVAC control boards during thermal tests—SMD types (2 × 40mΩ, 3W) couldn't handle 80°C near the current sense area. Their metal strip resistors solved it with superior thermal stability, low TCR, and reliable soldering. Zero failures across 20K+ units—problem solved.
