The through-hole press-fit tails align the part before soldering, simplifying assembly. At 2.50 mm pitch, this header occupies a compact board footprint — the 3 positions fit in a row width determined by the pitch and position count. Insulation height of 0.299 inch (7.60 mm) provides clearance for mating receptacle housing. ## Environmental and Safety Ratings The base product number is S03B-XAS; the full order code S03B-XASK-1(LF)(SN) includes the (LF)(SN) suffix for lead-free and tin-plate finish.","metaTitle":"JST S03B-XASK-1(LF)(SN) Header – 3 Pos, 2.5 mm, Right Angle","metaDescription":"JST XA series 3-position single-row right-angle header, 2.50 mm pitch, 3 A, 250 V, tin-plated, UL94 V-0.
