Board Layout Fit: 0.80mm Pitch and 3.95mm Stack Height
The BM08B-SURS-TF(LF)(SN): The 0.80mm pitch on this single-row header sets a tight board footprint — plan for fine-pitch routing between pads, especially if the PCB has multiple signal layers. The mated stack height of 3.95mm is fixed, so the mating receptacle must sit at that exact gap above the board; no adjustment for taller or shorter mezzanine spacing.
Signal-Duty Current and Temperature Envelope
Rated 0.2A and 0.5A per contact — this is strictly signal-level current, not power. The dual rating likely reflects a derating at elevated temperature; at 85°C ambient the lower figure applies. The 30V voltage rating matches the fine-pitch insulation limits. Operating temperature from -25°C to 85°C suits indoor consumer electronics, office equipment, and light industrial gear. No IP rating is listed, so this is an unsealed connector — keep it away from moisture or washdown areas.
Sourced through independent distribution channels.
This header mates with a SUR series receptacle (crimp or IDC type) for board-to-cable/wire connections. The 0.80mm pitch and single-row layout are mirrored in the mating half. Termination is solder-only — no press-fit option. The SMT pads need a reflow profile compatible with the nylon housing's UL94 V-0 rating; the material can handle standard lead-free soldering temperatures.
