Samtec AcceleRate® HD Ultra-Dense Mezzanine Strips
Samtec AcceleRate® HD Ultra-Dense Mezzanine Strips feature a low-profile 5mm stack height, slim 5mm width, and a 0.635mm pitch. These micro interconnects are super dense with up to 240 total inputs/outputs (I/Os). The four-row design allows 10 to 60 positions per row. Samtec AcceleRate HD header and socket connectors are PCIe® Gen 5 compatible, support 56Gbps PAM4 (28Gbps NRZ) applications, and feature an Edge Rate® contact system that is optimized for signal integrity performance. The solder ball technology self-aligns for simplified processing while the open-pin-field design offers grounding and routing flexibility. These mezzanine strips are compatible with Samtec UMPT/UMPS Ultra Micro-Power Connectors for flexible two-piece power/signal solutions.
