What this Micro-Fit+ header does in the assembly
The 2182160220 is a 2-circuit, 2-row, shrouded header from the Molex Micro-Fit+ 218216 series, designed for board-to-cable/wire connections. The 3.00mm pitch sets the PCB footprint and the per-contact current ceiling — the actual current depends on the wire gauge used in the mating receptacle. The locking ramp on the shroud provides a positive mechanical latch that resists vibration-induced separation, a common requirement in automotive and industrial equipment.
SMT termination and solder retention
The 0.390-inch (9.91mm) insulation height provides clearance for the mating receptacle's latch and wire strain relief.
Mating connector and system compatibility
The 2182160220 mates with Micro-Fit+ 218216 series receptacle housings that accept the matching crimp terminals. The 2-circuit, 2-row configuration with 3.00mm row spacing (same as pitch) means the mating receptacle must also be a 2x1 layout. The locking ramp on the header engages with the latch on the receptacle housing for a secure connection.
