QFS-032-04.25-H-D-DP-PC4 Application Field and Working Principle

Introduction

Rectangular connectors are an important type of connecting component in electronic equipment. The QFS-032-04.25-H-D-DP-PC4 models are a member of the arrays, edge type, mezzanine (board to board) series. This section will introduce their application fields, working principles, and related technical parameters.

Application fields

The QFS-032-04.25-H-D-DP-PC4 model is applicable for PC4 edge types and board to board mezzanine applications, such as in automotive products, industrial control computers, robotics, medical equipment, communications systems and consumer products. The PC4 version is compliant with current industry standards, making it suitable for high-speed circuit and data connections.

Working principles

The QFS-032-04.25-H-D-DP-PC4 model consists of two independent parts- a high-density press-fit base and a stainless steel protection cover. The press-fit base consists of multiple contact ribs that help in providing a tighter fitting than usual. The stainless steel protection cover is designed to reduce signal loss, decrease interference, and protect the connecting pins from damage due to external factors. The press-fit base ensures that the plug and the socket are firmly connected to each other.

Technical parameters

The technical configuration of the QFS-032-04.25-H-D-DP-PC4 model includes a board to board distance of 4.25mm, a linear current rating of 1.00A, an insulation resistance of 1000M ohms, a voltage rating of 200Vac, an operating temperature range of -55°C to +125°C, a rated current of 50mA, and a dielectric withstand rating of 200Vac. The QFS-032-04.25-H-D-DP-PC4 model has a contact resistance of 20m ohms and an insulation resistance of greater than 2M ohms. It has a minimum mounting force of 7N and a max rating of 300V. The thermal impedance rating of the QFS-032-04.25-H-D-DP-PC4 model is 0.5°C-in2/W and the peak reflow temperature is 220°C.The standard pack of the QFS-032-04.25-H-D-DP-PC4 model includes a connector body, pins, board-locking clips and retaining clips. The cable to board part is UL 94V0 approved, and the board to board part is UL-Recognized for up to 300VAC.

Conclusion

The QFS-032-04.25-H-D-DP-PC4 models are high-performance rectangular connectors which are suitable for edge type, board to board, mezzanine applications. They provide high-speed circuit and data connections, and have been designed to meet industry standards. The technical configuration of the QFS-032-04.25-H-D-DP-PC4 model includes a board to board distance of 4.25mm, a linear current rating of 1.00A, an insulation resistance of 1000M ohms, a voltage rating of 200Vac, an operating temperature range of -55°C to +125°C, a rated current of 50mA, and a dielectric withstand rating of 200Vac.
