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.","metaTitle":"BM08B-SURS-TF(LF)(SN) JST SUR Header, 8 Pos, 0.8mm, SMT","metaDescription":"JST SUR series 8-position SMT header, 0.80mm pitch, shrouded 4-wall, tin contacts, rated 0.2A/0.5A, 30V.
