MOLEX / WALDOM 39289128 Mini-Fit Jr. Power Connector

The MOLEX / WALDOM 39-28-9128 Mini-Fit Jr. Vertical Header is a robust connector solution for power and wire-to-board applications. This header features a dual-row design with 12 circuits and a 4.20mm pitch, making it suitable for a variety of electronic devices. The snap-in plastic peg PCB lock ensures a secure and reliable connection, while the gold plating on the mating interface and matte tin on the termination interface provide excellent conductivity and solderability. For increased amperage requirements, consider using the Mini-Fit® Plus HCS family terminals and headers. Refer to Molex Product specification PS-5666-001 for current de-rating information.
