What this 3-position Metrimate header does
Current rating and thermal derating
At 7.5 A per circuit and 600 V, this header handles moderate power distribution. The operating range of -55°C to 130°C means the 7.5 A rating holds at 25°C ambient; above 85°C, derate per the Metrimate curve to keep the contact temperature rise within the housing's UL94 V-0 polyamide limits.
Mating and mounting fit
This header mounts through-hole with solder termination. The contact post length is 0.186" (4.72 mm), suitable for standard PCB thicknesses. The mounting flange provides additional mechanical retention to the board.
