11-Position SMT Header for SL Wire-to-Board Systems
The 0740990011: A latch holder on the fastening type provides positive retention once mated — useful in applications where vibration could otherwise back the connector pair apart. Termination is surface-mount, so the header reflows with the rest of the board-side components.
Position Count and Series Siblings
At 11 positions, this header sits between the 8-position 0740990008 and the 4-position 0740990004 in the same SL 74099 series. If your BOM calls for 11 circuits, this is the exact fit. Dropping to the 8-position version means losing three lines; stepping up to a 12-position would require a different part number and a board layout change.
Mating and Application Fit
The header mates with SL series crimp receptacle housings that accept 22-28 AWG wire. Typical applications include automotive, general purpose, industrial, and medical equipment — environments where a reliable wire-to-board connection with moderate current (up to 3 A per contact, per the SL series rating) is needed.
