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.","metaTitle":"SM03B-GHS-TB JST GH Header 3 Pos 1.25mm SMT Right Angle","metaDescription":"JST GH series 3-position shrouded header, 1.25mm pitch, SMT right-angle, 1A/50V, locking ramp, UL94 V-0.
