3-Circuit SMT Header – Board-Fit and Sourcing
The 55450-0369 is a 3-circuit SMT pin header from Molex, described as a Mini-MI2 SMT wire-to-board assembly without a boss. The 'no boss' feature means the plastic housing lacks a locating peg — the board footprint relies solely on the SMT pads for alignment during reflow, which simplifies the PCB layout but demands precise solder-paste deposition to prevent skew.
