A latch holder locks the mating receptacle in place — no secondary clip or screw needed, which saves assembly time in high-vibration environments like automotive or industrial panels. Gold plating on the mating face at 30.0 µinch (0.76 µm) supports repeated mating cycles — expect 500+ cycles before contact resistance rises significantly. ## Pitch, Positions, and Board Footprint At 3.50 mm pitch, this header occupies more board space per circuit than a 2.54 mm part but carries higher current per contact — the wider pitch reduces mutual heating between adjacent pins. The 12 positions are all loaded, so no dummy pins. ## Voltage, Temperature, and Flame Rating Rated 400 V — this covers most industrial and automotive bus voltages (12 V, 24 V, 48 V, 120 V, 230 V) with ample margin. LCP also resists creep at high temperatures, maintaining pin retention over the product lifetime.","metaTitle":"Molex 1722981312 Ultra-Fit Header, 12 Pos, 3.50 mm, Gold","metaDescription":"Molex 1722981312 Ultra-Fit 172298 header, 12 circuits, 3.50 mm pitch, 400 V, gold mating contacts.
