Product details

3-Pin 1.25mm Pitch SMT Header for GH Wire-to-Board

The SM03B-GHS-TB: This is a JST GH series 3-position shrouded header, 1.25mm pitch, surface-mount right-angle — the board-side half of a compact wire-to-board interconnect for signal and low-power circuits. The 4-wall shroud protects the rectangular tin-plated contacts from handling damage and guides the mating housing into alignment.

SMT Right-Angle Mount and Solder Retention

JST lists this as an active part — no EOL notice, no successor to chase. Sourced per RFQ against your BOM quantity. RoHS status is listed as non-compliant — verify your local exemption or if a lead-free variant is needed.

Frequently asked questions

Where can I buy SM03B-GHS-TB and what is the lead time?

We source SM03B-GHS-TB per RFQ against your BOM quantity. Submit an RFQ for your target volume.

What is the mating housing for SM03B-GHS-TB?

This header mates with the JST GH series receptacle housing (order code typically starts with 'SHR-xxV-S-B') and uses the GH crimp terminals (order code 'SSH-003T-P0.2'). The locking ramp on the header engages the latch on the receptacle for a vibration-resistant connection.

What is the closest pin-compatible alternative to SM03B-GHS-TB?

Within the GH series, the 2-position variant (SM02B-GHS-TB) and 4-position variant (SM04B-GHS-TB) share the same 1.25mm pitch, SMT right-angle footprint, and locking ramp — only the position count changes. No direct cross from another series is documented.
