It uses a 3.00 mm pitch and mates with the standard Micro-Fit 3.0 receptacle housing and crimp terminals. The gold-plated mating contacts (15.0 µin) handle repeated mating cycles without fretting corrosion, while the tin-plated solder tails (100.0 µin) wet well during wave solder. Operating from -40°C to 105°C with a UL94 V-0 LCP housing, it is suited for enclosed equipment where flame rating is required. The 3.00 mm pitch and 0.118\" row spacing give enough creepage for the 600 V rating without forcing an oversized board footprint — a practical balance for mixed-signal boards where power and low-voltage traces share the same layer. The 8 A per contact rating assumes all circuits are loaded at 25°C ambient; derate above that per the Micro-Fit 3.0 derating curve in the product drawing.","metaTitle":"Molex Micro-Fit 3.0 430451213, 12 Pos Header, 8A, 600V","metaDescription":"Molex 430451213 Micro-Fit 3.0 header, 12 circuits, 2 rows, 3.00mm pitch, 8A, 600V, gold mating contacts.
