QFSS-052-04.25-H-D-A array, edge type, mezzanine (board to board) connectors are used for a variety of applications including power, signal, and datacom/telecom applications. These connectors come in different form factors based on specific application requirements, and are comprised of two contacts arranged in an array.

The edge type is typically used for low speed and power connections where circuit boards are separated by a gap of 1 mm or more. The mezzanine allows circuit boards to be stacked side by side or top-to-bottom and maximizes the number of contacts in a small space while minimizing crosstalk.

The QFSS-052-04.25-H-D-A connector\'s key features are versatility, durability, and cost-effectiveness. The connectors are rated for a current rating up to 8 A, a mating cycle life up to 50 - 500 cycles, and an operating temperature range of -40oC to + HD 85oC.

The connectors\' construction consists of two contact arrays, a press-fit type housing, and a shielding part. The contact arrays are made from copper alloy for maximum electrical performance, and the housing is made from UL 94V-0 rated polyamide material for maximum durability. The shield is made from stainless aluminum for a higher mechanical and electrical performance.

The QFSS-052-04.25-H-D-A connector\'s working principle is simple yet effective. The two contact arrays are located in the press-fit type housing and are connected the two circuit boards being joined. When two circuit boards are joined, the contacts in each array are aligned and both sides are held together by the press-fit housing. When power is flowing through the connector, the contacts act as small resistors, directing the current through the pins and into the boards.

QFSS-052-04.25-HD-A array, edge type, mezzanine (board to board) connectors are ideal for applications that require a robust connection between two printed circuit boards. They are simple to install, cost-effective, and provide exceptional electrical performance. They are rated for use in harsh environments and are UL94V-0 rated, making them a great choice for a wide variety of applications.
