ESQT-104-03-SM-D-326 is one of the series of rectangular connectors developed for use in a wide variety of applications. This connector is specifically suited for use in high-frequency and high-voltage applications due to its high current density, wide temperature range and low insertion force. The ESQT-104-03-SM-D-326 is a 4-pin, surface mount (SM) header connector in a dual type B format. It is rated for a current rating of 1.5 amps and a voltage rating of 350 VAC. The contact retention force is 15N. It is designed to mate with male headers or receptacles.

The main purpose of rectangular connectors such as the ESQT-104-03-SM-D-326 is to provide reliable electrical connections between two or more components. They provide a secure and reliable environment for the transfer of power. To achieve this purpose, the rectangular connector must be able to withstand high levels of current, a wide range of temperatures, and provide consistent contact force between the two components. In addition, the rectangular connector must be durable enough to withstand high levels of vibration and shock.

The basic structure of rectangular connectors consists of several terminals, which make contact with the mating connector, and an insulator body that separates the terminals from the surrounding environment. The contact terminals are typically either flat or rounded metal pins. These pins have a curved surface, which ensures a snug and secure fit while providing the necessary electrical connection. To ensure good contact, the pins are usually gold plated. The insulator body typically consists of two plastic pieces that snap together to form a secure fit.

The terminal pins of the rectangular connector are designed to make contact with their respective connectors in one of two ways. The first way is through a pre-applied insert, which is firmly secured in place within the insulator body. This ensures a consistent contact force regardless of the orientation of the plug and receptacle. Alternatively, a \'floating\' contact can be used, in which the contact fingers float within the insulator body, allowing for flexible orientation of the plug and receptacle.

The ESQT-104-03-SM-D-326 is a typical example of a rectangular connector. It can be used in a wide variety of applications, including high-frequency and high-voltage applications, as well as applications that require a secure and reliable connection. Its high current density, wide temperature range, and low insertion force make it suitable for many different types of applications. With this type of connector, engineers and technicians can rest assured that their electrical connections are secure and reliable.
