ESQT-125-03-G-5-375 is a type of Rectangular Connectors - Headers, Receptacles, Female Sockets. It is mainly used for high-density, high-throughput signal transmission between boards or modules. This type of connector improves the traditional connector’s current rating, temperature rating, and durability factors while maintain low cost. Its low profile design also contributes to better heat dissipation and insulation performance during transmission.The main application field of ESQT-125-03-G-5-375 is for varieties of small electronic devices and boards. Examples include telecommunication devices, portable media players, security systems, point of sale registers, medical monitors, wearables, and tablet docks. Due to the compact size and low profile design, it also works particularly well for PCBs and modules with limited space, especially in devices such as laptops with limited space and heat dissipation.The working principle of this type of connector involves establishing electrical connection on two perpendicular boards. The connectors consists of several components which include: the insulator, metal contacts, and retainers. Initially, the insulators will be placed in the desired position. Following that, metal contacts will be inserted through the insulator and folded against the electrical pad side. Then, a retainer is drawn to secure the connectors and pads. This creates a strong contact that is firmly holds the component to the board.The contacts in the connector serves several functions. First, the contacts hold a metal strip in place against an electrical pad on the board. This ensures that current flows from the connecting board and prevents sparks or shorts from occurring due to the contact point. Secondly, the contacts also provide a good connection and insulation, preventing any leakage of current. Lastly, the contacts also provide mechanical stability in terms of holding the connectors firmly in place to the board.The components used in ESQT-125-03-G-5-375 are designed to be durables and are suitable for long-term operation. They are also able to withstand extreme temperatures and harsh environments. In addition, the connectors are resistant to abrasion, impact, and corrosion which makes them suitable for use in dry, wet, and humid conditions. The built-in locking mechanism also provides a secure connection, making it ideal for applications in industrial equipment. Overall, ESQT-125-03-G-5-375 is a versatile and cost-effective solution for board connections. It provides an easy and reliable connection while also being able to withstand extreme temperatures and harsh environments. With its low profile design and compact size, it is an ideal choice for small electronic devices and in limited space applications.
