Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are high-density, user-configurable connectors utilized in various applications from automotive and consumer electronics to industrial systems and medical equipment.

The QTH-090-03-C-D is one such connector specifically designed for high speed differential applications. The connector provides a high-density, shielded, hybrid interface consisting of three power and signal contact arrays arranged with a guide pin on the mating face and mounted on a low-profile modular format. The purpose of the guide pin is to facilitate reliable, high-density mating of the connector and to help ensure precision mating of the array elements.

The QTH-090-03-C-D connector is suitable for a range of application fields from high frequency data transmission and control to sensor applications in electronic equipment. Its advantages include its low profile, its availability in multiple orientations, and its suitability for high-speed transmission of analog and digital signals with low crosstalk.

The working principle of the connector is based on a combination of contacts, a dielectric, and a shield. The contacts, typically made of phosphor bronze, are positioned in the connector in a grid arrangement that allows for high-speed transmission of electrical signals. The dielectric insulates the contacts and the shield provides improved electrical noise immunity.

The connector contacts also use a variety of polarization features such as lancing tabs and ramp lancing to ensure that the contact tails have formed a reliable electrical connection. The mating process can be automated by using special mating tools or manual mating tools with guide pins. The connector contacts can also be configured to accept specialized high-speed and high voltage differential signals.

The QTH-090-03-C-D connector is an ideal solution for applications where a high-density, shielded, hybrid interface is required. Its ability to maintain signal integrity through its reliable contact system, high-speed transmission capabilities, and low profile form factor make it a popular choice for a variety of applications.
