Product details

Right-Angle SMT Header for Board-Edge Harness Connections

The SM03(4.0)B-BHS-1-TB(LF)(SN): The tin-plated mating finish is suited for moderate mating cycles (typically 30–50 cycles) in indoor equipment.

No stock-holding claim – each RFQ is sourced through independent distribution.

The SM02(4.0)B-BHS-1-TB(LF)(SN) is the 2-position version of this same header – identical pitch, orientation, plating, and ratings. If your BOM calls for 2 positions, that part saves one circuit of PCB real estate; if you need 3, this is the one. The non-LF(SN) variant SM03(4.0)B-BHS-1-TB is electrically identical but may not carry the same RoHS documentation suffix – verify your compliance requirement before substituting.

Frequently asked questions

What is the pitch of the SM03(4.0)B-BHS-1-TB(LF)(SN) header?

The mating pitch is 0.157" (4.00 mm).

Is SM03(4.0)B-BHS-1-TB(LF)(SN) RoHS compliant?

Yes, it is RoHS compliant as indicated by the (LF)(SN) suffix in the order code.

What is the mating connector for this header?

It mates with a JST BH series receptacle (female housing with crimp terminals) of the same 3-circuit count and 4.00 mm pitch.
