The connector is designed primarily for use in high-density equipment applications such as telecommunications, high speed networking, servers, and storage. It is also suitable for PCB applications, wire-to-board applications, and board-to-FPC applications. In addition, the ESQT-120-02-F-D-665 is an ideal choice for high-speed, high density, space-saving applications in computing, communications, and other industries where small size and high reliability are needed.

Working Principle of ESQT-120-02-F-D-665

The ESQT-120-02-F-D-665 is a type of rectangular connector designed to allow technicians to quickly make reliable connections between two electronic devices. This versatile connector is easily installed and is designed to meet the high-speed/high-density requirements of a variety of applications.

In the ESQT-120-02-F-D-665, pins are either press-fitted or thru-hole soldered into a solder cup. The pitch between the pins is 2.5mm and the contact fingers are gold plated. This type of connection provides reliable electrical contact while maintaining an improved retention force and a low profile.

Also, the pins are polished to minimize potential contact resistance or crosstalk. Then, a dielectric separator is inserted between the pins which acts as an insulator and increases signal integrity. In addition, the contact resistance is maintained by using a contact-door mechanism, which means the contact pressure is kept equal between all points of contact of pins on the connector.

The ESQT-120-02-F-D-665 is configured with an SPQ style, which means it is available in two different layouts. These layouts include a dual row or a dual channel arrangement. Additionally, the ESQT-120-02-F-D-665 is equipped with isolation material between the pins for insulation. This insulation helps to reduce crosstalk and backdrive current and also reduces shrinking due to heat.

The ESQT-120-02-F-D-665 is also UL compliant and RoHS compliant. It has a UL 94V-2 flammability rating and is qualified for temperatures up to 125°C. It is also available with an option of mounting tabs for convenience.

Conclusion

The ESQT-120-02-F-D-665 is a versatile connector that is designed to be both low cost and reliable. Its application field is broad and it is suitable for a variety of high-speed, high-density, space-saving applications. It is anexcellent choice for PCB applications and offers reliable electrical contact while maintaining a low profile. Additionally, it is UL compliant and RoHS compliant, making it a great choice for applications where reliability and durability are needed.
