The ESQT-138-03-M-D-310, a rectangular connector belonging to the Headers, Receptacles, Female Sockets category, is a high-quality part used in many types of electronics. To better understand its use and operation, let\'s explore its application field and working principle.

Application Field

The ESQT-138-03-M-D-310 is a popular choice among engineers for PCB-connecting and other electrical interconnecting applications. It is especially useful in applications requiring a slim profile, robust high temperature performance, and reliable electrical contacts. Its features make it an ideal choice for applications such as motor control, automotive, telecommunications, control systems, and embedded computing.

In terms of features, the ESQT-138-03-M-D-310 provides a slim profile that allows it to fit into tight spaces with ease. It also boasts robust high temperature performance thanks to its UL 94V-0 rated black thermoplastic housing, which is capable of withstanding temperatures of up to 175°C. Additionally, the ESQT-138-03-M-D-310\'s two rows of gold-plated contacts lend it excellent electrical corrosion resistance. Lastly, the connector is UL approved and RoHS-compliant, making it suitable for use in all manner of commercial applications.

Working Principle

The ESQT-138-03-M-D-310 is designed to be used when connecting two or more printed circuit boards (PCBs). When used, the contacts within the connector are aligned with the PCBs, allowing for the transmission of electrical signals between them. The connectors are constructed with an array of dual-row female contacts, which are terminated on the inside of the connector body.

Once connected, the female contacts establish an electrical connection with the male contacts on the PCBs. This electrical connection allows for the transmission of signals between the two PCBs. Furthermore, the connector\'s thermoplastic housing serves to provide the contacts with physical protections, as well as protection against dust and dirt.

In addition to providing electrical interconnectivity between two or more printed circuit boards, the ESQT-138-03-M-D-310 is also useful in providing EMI protection. When the connectors are properly mated, their thermoplastic housings provide a physical barrier between the PCBS and the environment, thereby preventing unwanted electromagnetic interference (EMI) from entering and impacting the functioning of the circuit boards.

Thanks to its robust features and EMI protection capabilities, the ESQT-138-03-M-D-310 has earned the trust of many engineers for use in a wide variety of electrical applications. Its slim profile, high temperature performance, reliable electrical contacts, and EMI protection make it ideal for motor control, automotive, telecommunications, control systems, and embedded computing, among other applications.
