The TMMH-139-04-H-5 is a type of rectangular connector, also known as a header, with male pins. Headers are commonly found in electrical and electronic devices, such as motherboards, sound cards and computer peripherals. They are used to connect two sections of an electronic circuit. Headers come in a variety of shapes and sizes, with the number of pins ranging from two to hundreds. The TMMH-139-04-H-5 is a 4-pin header, commonly used for applications where a low profile design is required.

TMMH-139-04-H-5 headers are designed to provide low cost, reliable and durable connections. Typically they are constructed from durable metal or plastic, and consist of a single row of four pins. The pins are inserted into a mating connector that is then soldered onto a PCB. The headers can be mounted on top of the PCB by either surface mount technology (SMT) or through-hole assemblies. In addition to providing electrical connections, they can also provide strain relief for cables connected to the PCB.

The working principle of the TMMH-139-04-H-5 header is quite simple. The male pins are soldered into the exposed copper traces on the PCB, providing the necessary electrical connection between components in the circuit. The mating connector is then secured to the board, either using mounting holes or through the use of SMT technology. This ensures that the electrical connection remains firmly in place even during physical environmental changes or vibration. Additionally, the design of the header minimizes the risk of interference with other circulating electrical signals.

The primary application of the TMMH-139-04-H-5 header is in the creation of internal PCB connectors. This type of header is commonly used in motherboards, sound cards, communication equipment and other types of electronics. It is also used to connect external components to the board, including cables, sensors and other devices. Due to its low profile design, it is particularly well-suited for use in portable, low-profile devices. It is also ideal for cases where the header cannot be shielded from external environment, due to its excellent EMI shielding properties.

In summary, the TMMH-139-04-H-5 header is a type of rectangular connector that offers a low-cost, reliable and durable connection between various components. Its small size and low profile design make it ideal for use in portable and low-profile devices, while its EMI shielding properties make it well-suited for any environment. Its primary application is in the creation of internal PCB connectors, but it can also be used to connect external components to the board. Its working principle is simple, with male pins that are soldered onto the PCB and a mating connector that is secured in place.
