The housing carries 4 positions but only 2 are loaded with male pins. That means the BOM circuit count is 2, not 4 — confirm the application needs exactly two signal or power lines before committing the line item. ## Mating and Shrouding This header mates with a Molex 3099-series receptacle housing (same series) — confirm the mating half order code from the series catalog.","metaTitle":"Molex 10-18-1040 Header – 0.198\" Pitch, 4 Pos, Active","metaDescription":"Molex 10-18-1040 shrouded header, 0.198\" (5.03 mm) pitch, 4 circuits (2 loaded), 5 A per contact, tin plating, UL94 V-0.
