Product details

5-Pin, 0.80 mm Pitch, SMT – JST SUR Board-to-Cable Header

The BM05B-SURS-TF(LF)(SN): The 0.031" (0.80 mm) pitch sets a compact footprint suited for dense PCB layouts where signal routing space is tight. It is a surface-mount (SMT) header with a shrouded 4-wall design and push-pull fastening — the shroud guides the mating female housing and protects the contacts from damage during blind mating. The tin finish is cost-effective for moderate-cycle applications (a few hundred mates) in indoor, non-corrosive environments.

Mated Stack Height and Board Clearance

The mated stack height is 3.95 mm, with an insulation height of 0.106" (2.70 mm). This low profile suits enclosures with limited z-height — for example, when routing a cable parallel to the PCB inside a shallow housing.

Sourced through independent distribution channels against an RFQ.

Frequently asked questions

What does the 0.80 mm pitch mean for board layout?

The 0.80 mm pitch sets the center-to-center spacing of the SMT pads. This is a fine-pitch connector — the PCB footprint must match the 5-position single-row layout exactly. The shrouded 4-wall housing also requires clearance for the mating female connector body.
