The header is through-hole soldered, with gold-plated mating contacts (15.0 µ\" gold) and tin-plated solder tails (100.0 µ\" tin). The dual-row layout with 12 positions means the board footprint occupies six positions per row, which is a common density for a 12-circuit power harness. The tin-plated solder tails are the economical choice for the one-time solder joint to the PCB. Against the 10-circuit sibling 430451210 at the same 3.00 mm pitch, the 430451228 adds two circuits per row — the footprint is wider by one position per row, but the pitch and row spacing are identical, so the same receptacle housing series mates with both. Choose the 12-position when the BOM calls for 12 circuits; the 10-position when the harness needs fewer conductors.","metaTitle":"Molex Micro-Fit 3.0 430451228, 12-Pos Header, 3 mm Pitch","metaDescription":"Molex 430451228 Micro-Fit 3.0 header, 12 circuits, dual-row, 3.00 mm pitch, through-hole, gold-plated contacts, 8 A, 600 V.
