Rectangular connectors are a classification of connectors that includes headers, male pins, female pins, single-row sockets, and double-row sockets, among others. All of these have their own distinct uses within various applications. This article will mainly focus on the 43650-1003 series, a specific type of header. Specifically, it will cover the application and working principles of the 43650-1003 series.

Application

The 43650-1003 series headers are primarily designed for use in applications where space is at a premium. While they are suitable for use outside of these confined areas, their ability to fit snugly in tight spaces makes them an ideal choice for embedded applications. Additionally, the 43650-1003 series headers feature a small size, a low profile, and a reliable build quality which make them well-suited for use in portable or mobile devices. They can also be used in automotive, industrial, and telecom applications.

Design

The 43650-1003 series are designed with a 4-pin single row configuration. They are available in a range of packaging options such as tape and reel and tube tray, for easy integration into manufacturing processes. The 43650-1003 series headers feature gold plating on the contact ends, ensuring reliable connections and high durability, even in the harshest of conditions. Additionally, the design of these headers allows for consistent terminal entry force and simple wire termination.

Working Principle

The 43650-1003 series headers are designed to function in an ‘insertion and removal’ manner. This means that they have a ‘keyed’ design which allows for easy and quick insertion and removal from mating components. Additionally, they feature a polarised design which helps to protect against wrong insertion. To ensure reliable connections, the contact pins on the 43650-1003 series are plated with gold. This helps to improve contact resistance and further protect the components from corrosion.

Another important principle in the function of the 43650-1003 series is the heat-sink capability. This allows them to dissipate the heat generated from high-power devices. Finally, the 43650-1003 series headers feature an anti-wicking design which helps to prevent the contact pins from wicking moisture and dirt. This helps to further improve the reliability and electrical characteristics of the headers.

Conclusion

In conclusion, the 43650-1003 series headers are a type of rectangular connector designed for use in embedded and portable applications. They feature a small, low-profile design with reliable build quality. Additionally, their heat-sink capability and anti-wicking design make them an excellent option for applications where heat dissipation and reliable connections are necessary. With a range of packaging options and gold-plated contacts, the 43650-1003 series is an ideal choice for a variety of applications.
