QFS-052-04.25-L-D-A Description

Short technical summary and product information.

The QFS-052-04.25-L-D-A is a 104-position high-speed ground plane receptacle from Samtec's QFS series. This connector features a 0.64mm (0.025") pitch, 2 rows, and surface mount termination. Contacts are gold-plated with 10µin (0.25µm) thickness over nickel, ensuring reliable signal integrity. The insulator is made of liquid crystal polymer (LCP), and contacts are phosphor bronze.

 

This receptacle is designed for mezzanine board-to-board applications with mated stacking heights of 10mm, 11mm, or 14mm. It includes a board guide and integrated ground bus (plane) for improved EMI performance. Electrical ratings include 2.6A per contact (2 pins powered) and 15.7A per ground plane, with a voltage rating of 300 VAC. The operating temperature range spans -55°C to +125°C.

 

The QFS-052-04.25-L-D-A is a single-ended type (type -D) with a lead style of -04.25 and plating option -L (10µin gold on contact, matte tin on tail). It is lead-free solderable and packaged in trays of 52 units. This connector supports high-speed protocols up to 25 Gbps NRZ, making it suitable for applications such as PCIe, USB, and Ethernet.
