77319-103R40LF

The 77319-103R40LF is a type of rectangular connector, which is a type of electrical connector featuring pins or sockets usually arranged in a rectangular pattern. Specifically, the 77319-103R40LF is a header, which is a type of male pin that has an electrical connection system. Headers feature two rows of pins that are mounted on a printed circuit board (PCB) and are designed to enable the mated connection of two separate circuits.

The 77319-103R40LF is mainly used in rugged and harsh environments with increased shock and vibration. This header uses straight as well as right angle mountings. This type of mounting reduces any space used between two panel components in a device. It has a current rating of 2A and a dielectric withstanding voltage of 1.5 kVAC. The rated current stress, on the other hand, is highly dependent on the wire size used. In fact, the 2A rating is achievable using a 0.9mm wire.

The 77319-103R40LF is also characterized by having a temperature resistance range of -25°C up to +85°C and humidity of 85%, a permitted amount of soldering heat of 230°C for 10 seconds, a contact material of phosphor bronze with gold plated edge contact, and a UL flammability rating of 94V-2.

One of the most remarkable features of the 77319-103R40LF is the way it works. Essentially, when it is connected to other components, just like other headers, it creates an electrical contact and allows current to flow between two electronic devices or components. In order to ensure that current flows continuously, the header utilizes a male pin design, which enables it to form a tight fit when mated with a female pin. To make sure that the connection is secure and reliable, these headers feature two rows of pins that make contact with two separtae circuits. This connection, thus, allows for the flow of current in a controlled manner.
