Current and Plating – 5 A with 100 µinch Tin
The 93939-408HLF: Tin is suited for occasional mating (under 50 cycles) in clean, dry environments; for frequent disconnect, a gold-plated sibling is the better choice. The 100.0 µinch (2.54 µm) tin thickness on the mating face is well above the 40 µinch flash typical of economy headers — this thickness resists fretting corrosion over the connector's service life.
