Active Sourcing for a Standard 3-Pin Header
Board Fit and Routing: 2.54 mm Pitch, Unshrouded
Current and Thermal: 3 A per Contact, Tin Finish
For repeated mating beyond a few hundred cycles, a gold-plated sibling would be a better choice — but for a fixed harness or low-cycle board interconnect, this tin finish holds up fine.
How This Unshrouded Header Differs from a Shrouded Sibling
The 9-146278-0-03 is unshrouded, single-row, 0.100" pitch, and uses a simple push-pull fastening. If your application needs polarization and a locking latch, the shrouded sibling is the correct choice; for a bare pin header that mates with a standard receptacle, this unshrouded part is the direct fit.
