ER8 Board-to-Board Connectors

Hirose Electric ER8 Board-to-Board Connectors feature an 0.8mm pitch in stacking and vertical variations, 7mm to 12mm stacking height, and 10 to 140 positions with stacking, vertical, and coplanar variations. The connectors incorporate a large mating guide, while the alignment on the plug offers easy insertion operation. The insertion loss-to-crosstalk ratio (ICR) with five-aggressor differential FEXT meets the IEEE802.3ap specification for 10Gbps with plenty of margins. Other features include 0.5A current rating, 100V_AC voltage rating, and 85Ω differential impedance at 35ps rise time (20% to 80%). Hirose Electric ER8 Board-to-Board Connectors operate in a -55°C to +125°C temperature range.
