Product details

Board Fit and Routing for a 4-Position Right-Angle Header

The 0022288041: With 4 positions in a single row, the header occupies minimal board edge, leaving room for adjacent connectors or passives. This saves z-height in tight enclosures and simplifies board-edge routing.

Plating and Environmental Rating for the Application

Rated for use in Automotive, General Purpose, Medical, and Telecommunications applications per the series listing — the tin finish and V-0 housing support these environments as long as the connector is not exposed to continuous moisture or corrosive atmospheres.
