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, 100VAC 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.
