Headers, Male Pins Procurement Notes

Verify the specific manufacturing date code upon receipt to ensure component freshness. Confirm that the gold and tin plating matches project requirements for corrosion resistance and conductivity. Ensure storage conditions prevent moisture absorption by the nylon housing prior to soldering. Validate that the 19-position count aligns precisely with the PCB footprint design.

Headers, Male Pins Selection Notes

Select this component when a vertical orientation is required for space-constrained layouts. The 2.54 mm pitch is compatible with standard DIP and breadboard systems. Consider the 750 VAC rating for applications requiring higher isolation than standard 250 VAC headers. Verify that the through-hole soldering process accommodates the specific pin length and barrel dimensions.
