The 78938-102HLF is a rectangular connector, also known as a header with male pins. It is a product of TE Connectivity, made up of a chip scale packaging (CSP) designed with a single surface soldering system to decrease the number of soldering operations needed in a PCB assembly. The 78938-102HLF can be found in a variety of applications and a few potential uses are provided below.

Communication Applications

Due to its detailed design, small form factor and robust smoke barrier features, the 78938-102HLF is suitable for communication applications. It has the ability to send data across far distances without signal contamination and can also switch between variable speed transmission modes. It also supports flexible functionality in transmitting audio and video data and can handle a wide range of communication protocols. The 78938-102HLF is officially certified to support high-bandwidth applications such as Ethernet, Fibrechannel, and Infiniband.

Consumer Electronics

The 78938-102HLF is also used in consumer electronics due to its small footprint and very low profile. It is capable of interconnects with fewer solder points and the ability to route both signal and power within the same unit means that it is easier to manage the circuits as compared to more traditional designs. Its slim profile is suitable for compact designs where space is of the essence, such as in TV’s, digital cameras, smartphones, tablets etc.

Industrial Applications

The 78938-102HLF is a suitable choice for industrial applications due to its EMC shielding features, which ensures interference or induction of unwanted signals is reduced. It is also able to support up to 4 channels, which allows it to be used to manage or control difficult cabling tasks. Its high reliability and precise design makes it suitable for devices or equipment that require an extremely robust connection. This makes it particularly suitable for use in heavy industry and factory operations.

Working Principle

The 78938-102HLF utilizes a single-surface soldering system, meaning that instead of using several solder points, the electrical components are soldered directly on the top of the IC (integrated circuit). This makes it easier to manage the connections and ensures fewer steps are needed to complete assemblies. The 78938-102HLF also utilizes a strong physical connection that is secure enough to tolerate repeated motion or shaking, making it suitable for use in vehicular and robotic applications.

The 78938-102HLF also makes use of EMC shielding to ensure electromagnetic interference and immunity are reduced to a minimum. This means that the signal noise within the electrical circuits is kept to a minimum, resulting in clearer, faster and more reliable data transmissions.

In conclusion, the 78938-102HLF is a reliable and efficient rectangular connector that is suitable for a wide range of applications, from consumer electronics to industrial and communication-related uses. Its single-surface soldering system and strong EMC shielding make it a viable choice for assemblies where robustness and flexibility are of the utmost importance.
