1.25mm Pitch Terminal Wafer SMT

A 1.25mm pitch terminal wafer SMT (Surface Mount Technology) refers to a specific type of electrical connector commonly used in electronics manufacturing. Let's break down what each term means:1.25mm Pitch: "Pitch" in this context refers to the distance between the center of one terminal (or pin) to the center of the next terminal on the connector. 

1. A 1.25mm pitch means that the distance between the terminals is 1.25mm. This measurement is crucial because it determines compatibility with other components or connectors on a circuit board.

Terminal Wafer: A terminal wafer is a type of connector housing that contains multiple terminals (or pins) arranged in a specific configuration. These terminals are used for making electrical connections between different components or circuit boards. The wafer typically has a plastic housing that holds the terminals in place and allows for easy insertion into a corresponding receptacle or header.

2. SMT (Surface Mount Technology): SMT refers to a method of electronic component placement and soldering on a printed circuit board (PCB). Components designed for SMT have small metal contacts or leads that can be soldered directly onto the surface of the PCB, as opposed to through-holes used in traditional through-hole technology. SMT components are smaller and offer better electrical performance and reliability in many applications.

So, when you combine these terms, a "1.25mm pitch terminal wafer SMT" would describe a connector with terminals spaced 1.25mm apart, housed in a wafer-style configuration suitable for surface mounting onto a PCB using SMT techniques. These connectors are often used in various electronic devices and applications where space-saving, high-density interconnections are required, such as in laptops, smartphones, and other compact electronics.
