What this 8-position right-angle header gives the board layout
The 9-146309-0-04: With 8 positions in two rows, the board gets four pins per row, all loaded, no empty slots. The unshrouded header means the pins are exposed after soldering; mating is push-pull with no latch.
Current, temperature, and flame rating — what they mean in practice
Rated 3A per contact, with the temperature ceiling at 105°C and a floor at -65°C. The 3A limit keeps the temperature rise inside the thermoplastic housing material's safe zone; push past it and the glass-filled UL94 V-0 housing still won't propagate flame, but the contact beam may anneal.
