Rectangular Connectors—Headers, Receptacles, Female Sockets—are versatile, self-contained electronic interconnection devices. This type of connector utilizes electrical signals to route communication to and from a circuit to associated systems or components. The 71991-425LF is one such type and is manufactured by TE Connectivity (NYSE: TEL), a global manufacturer of connectivity and sensor products.

The 71991-425LF is a through-hole right angle receptacle and header that is terminated with plated-through standard tin-lead solder tails. It features an environmentally-friendly matte tin finish over copper lead frame. This module offers a large range of mechanical and electrical mating options and can be easily interconnected. Additionally, it offers a robust design with improved durability and high reliability.

When it comes to applications, the 71991-425LF is suitable for a wide variety of industrial, automotive, consumer electronics, and other applications requiring a robust connection. In an automotive environment, the product is suitable for instrument panel and fuse box connections, as well as transmission/powertrain connections. It is also appropriate for HVAC systems, consumer appliances, medical equipment, battery management and more. Additionally, the product can be used for military/aerospace applications.

The main working principle behind the 71991-425LF is its ability to transmit an electrical signal through a shielded or unshielded connection. The signal essentially travels from one port to another in the form of a differential or single-ended signal. When the signal arrives at the module’s destination, it is translated into a digital or analog format.

The 71991-425LF is designed with a wide range of features, including a completely removable and interchangeable core, a polarizing key design, secure mating retention, an optional crimp-style latch, and optional painted to order. Additionally, the product’s lead frames are designed with a two-piece construction that can reduce misalignment and the need for soldering. There are also optional solder tails available in a wide variety of configurations.

In terms of assembly, the 71991-425LF can be attached with either an overmolded or molded-in-place style. Or, components can be flame-soldered or laser welded with a low-temperature soldering process. Additionally, modules can be integrated into secondary operation with the help of specialized inserts.

Depending on the application, the 71991-425LF can be operated on 0.5A current, 2 A rated voltage, and up to 0.4A rated current. It is rated for 250V peak-rated power, and its AC and DC contact resistances are less than 30 milliohms. The product is designed with AMP connectors, which are UL94V-0 compliant, and is RoHS compliant.

Overall, the 71991-425LF is a versatile and reliable through-hole right angle receptacle header. It is designed to meet a wide variety of electrical and mechanical requirements and is suitable for a range of applications, including automotive, industrial, and consumer electronics. Its main principle of operation is based on transmitting an electrical signal from one port to another in the form of a single-ended or differential signal.
