Key Features
- Lower Df (0.013) than standard S1000-2 (0.018) for 28% loss reduction
- Same Tg 180C and thermal reliability as S1000-2
- Cost-effective bridge between FR-4 and low-loss materials
- Proven for 10G-25G SerDes channels under 20 inches
- Widely used for cost-sensitive high-speed applications
Applications
Shengyi S1000-2M is proven in production for: automotive ADAS (10G links), 10G/25G Ethernet switches, consumer 5G routers, HDI boards with moderate signal integrity, cost-optimized networking.
How It Compares
S1000-2M is the mid-loss variant of S1000-2, offering ~28% lower dielectric loss (Df 0.013 vs 0.018) at minimal cost premium. For links under 20 inches at 10-25Gbps, it eliminates the need for S7040G or Megtron 6.
