Header, 0.1" pitch, 40 pin, female, gold, vertical, surface mount.
These wire wrap pin (0.64mm square) receptacles are very strong and fit all standard solderless and solder-in breadboards. They are the recommended pin type to use for prototypes that will be repeatedly plugged and unplugged.
For production boards and DIP package replacement, where a smaller pin diameter is required, we recommend using our machine pin headers (0.45mm round) instead.
These female gull wing headers fit the bottom side pads on all of our SMT to DIP Adapters, as well as our surface mount connector adapters (including FPC adapters and Dual Row Adapters).
