QTH-120-03-F-D-LC is a type of edge type mezzanine connector specifically designed to provide connection between boards. It is well-suited for applications where size constraints necessitate a dense yet reliable connection including consumer electronics, cellular phones, radio frequency (RF) and more. This article will provide a detailed overview of the application fields and working principle of the QTH-120-03-F-D-LC.

Applications of the QTH-120-03-F-D-LC can be broadly divided into consumer electronics, radio frequency (RF), and more. In consumer electronics, especially cellular phones, the QTH-120-03-F-D-LC can provide connections between boards with minimal size requirements yet reliable performance. Additionally, it can withstand environmental and static stresses including signal integrity, humidity, and temperature changes. The QTH-120-03-F-D-LC connector is also capable of providing RF connections in automotive, telecommunications, medical, industrial, aerospace, military, and power generation applications.

The QTH-120-03-F-D-LC can be identified by a few key characteristics. Its edge type mezzanine design features three rows with 0.100" pitch and 120 contacts. It is available in either stamped contacts for cost-effective solutions or die-cast contacts for high reliability requirements. It is available in two different contact types, female and male, each with floating or locking capabilities. The contact area is protected by a dual wall insulator, made of PBT to reduce signal attenuation and cross-talk. Furthermore, it is rated for a current rating of 2A.

The working principle of the QTH-120-03-F-D-LC is relatively simple. The board-to-board connection is established via a low-profile edge type mating interface. This allows for minimal size requirements while also ensuring a secure connection. The contact interfaces are held in place via press-fitted detent or locking push-pull mechanisms, preventing the connection from loosening or damaging during use. Additionally, the contact interfaces are made of a nickel-plated steel material, ensuring a low self-inductance.

The QTH-120-03-F-D-LC is a great choice for edge type mezzanine connection application that require a reliable, dense, and cost-effective connection. Applications in consumer electronics, medical, industrial, automotive, telecommunications, aerospace, military, and power generation industries are well-suited for the QTH-120-03-F-D-LC. Its low profile yet reliable edge type designs make it suitable for a wide range of applications. Furthermore, its dual wall insulator and floating/locking contact mechanisms provide the necessary protection against environmental and static stresses while also ensuring a secure connection.
