Introduction

The ESQT-104-03-S-D-326 is a 4 pin, male connector header that is a part of the Rectangular Connectors - Headers, Receptacles, Female Sockets category. This particular connector is made of plastic and is meant to provide an efficient method of connecting external wiring to a circuit board or an interior system. It is designed for low to medium current applications and can be easily installed and removed from a PCB.

Application Field

The versatility of the ESQT-104-03-S-D-326 makes it an ideal choice for various different types of applications. This connector can be used in a broad range of electronics, from consumer electronics such as personal computers, televisions, and other computing devices, to industrial applications like telecommunications and automotive electronics. As such, it can be found in a wide range of applications from small, hand-held devices to large scale industrial systems.

Working Principle

The ESQT-104-03-S-D-326 is composed of two parts – a header and the connector. The header end is designed with a 2.54 mm (0.1 in) pitch which is the standard distance between pins. This makes it easy to install it onto a circuit board. The other end of the connector (the "female" end) contains four pins, machined to meet the exact requirements for a specific application. This ensures a secure connection between the header and the circuit board, while at the same time allowing the easy removal of the connector.When connecting the ESQT-104-03-S-D-326, pressure is applied to the front of the header via the four screws that hold it in place. This action creates a secure connection between the header and the circuit board and allows for electrical current to pass through the connector. There is also protection against high-frequency noise interference, making it suitable for low to medium current applications.

Conclusion

In conclusion, the ESQT-104-03-S-D-326 is ideal for low to medium current applications in most types of electronics, from consumer electronics to industrial systems. Its 2.54 mm (0.1 in) pitch makes it easy to install and the four pins ensure a secure connection between it and the circuit board. The pressure applied to the screws allows for a secure connection and also provides protection against high-frequency noise interference.
