Rectangular Connectors – Headers, Receptacles, Female Sockets include the SQT-125-01-F-D. This versatile and sophisticated device has numerous applications and works on a variety of principles. It can be used in a multitude of different electrical connections.

The SQT-125-01-F-D is a rectangular two-position, closed-end, wire-to-board connector. This connector is structured so that it is symmetrically arranged in an X-Y fashion, and can be soldered to a PC board. This connector also has a variety of variants; the F denotes female, and the D signifies a 90-degree vertical polarized type.

The connector’s high current capacity of 4.0 amps (20-14 AWG) offers improved heat resistance, making it ideal for applications requiring higher currents. The small size allows for a close fit with other connectors, enabling a compact design that’s well-suited for space-constrained electronic systems. The standard “uncrimped wire” type also allows for quick assembly and easy maintenance.

The SQT-125-01-F-D is particularly useful in the automotive industry. Its excellent electrical characteristics help reduce electromagnetic interference and radio waves. Its high durability and mechanical strength make it well-suited for resisting shock and vibration. Its low temperature coefficient and dielectric strength also make it suitable for the harsh environmental conditions found in motor vehicles.

The standard operating principle for the SQT-125-01-F-D is crimp/solder attachment. This process requires that a solid section of wire is crimped to the connector, and then soldered onto a printed circuit board (PCB). This is the most common and reliable way to attach wires to a board. The crimp/solder process is a cost-effective approach, as it utilizes the same materials throughout the entire process.

In addition to the crimp/solder method, the SQT-125-01-F-D connector also comes with solderless options. These options enable assembly without the need for soldering equipment. Instead, the terminals of the connector are pre-loaded into a housing, which is then simply snapped onto the PCB. This process is both easier and faster than the crimp/solder method, and is popular with automated assembly operations.

The SQT-125-01-F-D connector is also suitable for through-hole and surface mount applications. In through-hole applications, the connector is inserted into the holes of the PCB, and the wires attached on the back side. This process requires highly precise cutting and drilling into the PCB. Surface mount applications require pre-loaded terminal pins integrated into the housing, which are then soldered directly onto the PC board. The SQT-125-01-F-D is popular for both through-hole and surface mount applications due to its small size and inconsequential weight.

In conclusion, the SQT-125-01-F-D is a versatile and sophisticated device that has a variety of applications and works on a variety of principles. It is suitable for a variety of electrical connections, and its crimp/solder and solderless attachment methods make it useful for both through-hole and surface mount applications. This makes it well-suited for a variety of industries, including automotive, home electronics, and telecommunications.
