QFS-078-01-H-D-RA-K

The QFS-078-01-H-D-RA-K is a type of rectangular connector, specifically belonging to the category of Edge Type Arrays, Mezzanine (Board to Board) connectors. As its name implies, this connector has a maximum number of 78 contacts and is configured for horizontal mounting. It is designed for a straight connection between boards, utilizing two separate rows of contacts on either side, making it the ideal choice for applications that require an effective but simple connection.

The connector’s simple board-to-board connection translates into increased signal integrity since there are fewer connection points. The QFS-078-01-H-D-RA-K also features an optional 0.4mm pitch, which can drastically reduce the space required for system-level integration. This makes the connector ideal for applications with high density and high port density including mobile phone baseband boards.

The QFS-078-01-H-D-RA-K operates by utilizing two rows of 78 contacts placed in alternating positions along both sides of the edge type array. One row of contacts is the signal contacts while the other is for ground return. The two rows are arranged in order, with the signal contacts alternating between being placed on the back side of the connector and the front side. This arrangement creates a balanced coupling between the two sides of the connector, thereby reducing transmission losses.

When connecting to the QFS-078-01-H-D-RA-K, the mating connector is designed to have a predetermined number of contacts that match those on the QFS-078-01-H-D-RA-K. This precise matching eliminates the need for adjusting the number of contacts when the mating connector is inserted into the array. Additionally, the contacts of the QFS-078-01-H-D-RA-K are all enclosed in a single housing block, preventing any loss of signal or power to the surrounding environment.

In summary, the QFS-078-01-H-D-RA-K is an excellent choice for applications with high port density requirements due to its high signal integrity, precise contact alignment, and 0.4mm pitch option. It is an ideal choice for connecting boards that require reliable yet simple connections between them.
