QFSS-104-04.25-H-D-A rectangular connectors (rectangular arrays, edge type, mezzanine (board to board)) are widely used in various fields and applications for high-speed transmission. It provides electrical interconnections between two PCBs or boards with different or same packages.

The connectors come in two different versions: removable and soldered. The soldered version features high vibration resistance, and it is ideal for use in harsh environments. For the removable version, both robust and accurate mating features are necessary to ensure consistently reliable connections.

The QFSS-104-04.25-H-D-A connector is designed to meet demanding application requirements such as high power density, high operating temperature, high signal integrity, low crosstalk, and guaranteed system durability. It features a horizontal robust design which allows for easy handling, fast assembly, secure connections, and provides excellent protection against shock and vibration.

The QFSS-104-04.25-H-D-A connector uses a high-density modular interface with up to 104 contacts per connector. It has a 4.25 mm contact pitch for high-density applications and an unmated height of 13.8 mm. The contact terminals are plated with tin for reliable electrical connection and durability.

The mating interface features a straight-pin configuration to ensure an accurate fit when connected, and it also features a self-guided housing mating guide and an outer shell that offers extra protection against dust and water intrusion. The connector also features a multi-row system of a single row male and female connectors with staggered wire entry. This ensures superior signal flow and improved system reliability and performance.

The QFSS-104-04.25-H-D-A connector is suitable for high-speed data transmission on printed circuit boards. It allows for a high-throughput data rate of up to 12 Gbps and a frequency range up to 7 GHz. Its low-resistance design ensures minimal signal loss, and it also reduces reflections, which can degrade the signal transmission.

The working principle of the QFSS-104-04.25-H-D-A connector involves establishing a reliable electrical connection between two devices. It uses its high-density contact terminals to create a low-impedance connection between the devices, providing a secure and robust connection. The contact terminals use gold plating to provide additional durability and a low contact resistance, ensuring reliable transmission.

The connector also features a high-temperature resistance which can withstand up to 125°C of continuous operating temperature. It also has an increased scratch-resistance surface which can provide extra protection and durability.

In summary, the QFSS-104-04.25-H-D-A rectangular connector is an ideal solution for high speed data transmission in a variety of applications. It features a robust design, high-density contact terminals, and high temperature resistance, providing increased reliability and performance.
