The insulation height of 0.167 inches (4.25 mm) gives clearance for the mating receptacle's latch. The rectangular contact shape and phosphor bronze base material provide consistent spring force over the rated temperature range of -25°C to 85°C.","metaTitle":"SM12B-GHS-TB(LF)(SN) JST GH Header 12 Pos 1.25mm SMT Right","metaDescription":"JST GH series header, 12 positions, 1.25mm pitch, SMT right-angle, tin contacts, locking ramp.
