The 91930-21109LF is a type of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board). It is used to connect individual contact circuits on an Interface Board and Route Cards, Bus Cards, and Communications Cards. This type of connector is commonly used in telecommunications, consumer electronics, video, computing, networking, and medical applications.

The 91930-21109LF has a contact arrangement of 203 with a total of 11 rows, with the first row having nine contacts. It also has an interfacial seal to protect the contacts from debris and dust. The contact plating used on this type of connector is gold with a minimum thickness of 30u inches. The contact finish is also a nickel finish.

The 91930-21109LF is a surface-mount connector which uses surface-mount technology or SMT. It consists of a bottom contact that is attached to the board and two sets of top contacts that attach to the capacitor or component. This connector offers high contact density due to its small size, and it’s also economical in terms of design and manufacturing cost.

The electrical performance of the 91930-21109LF meets the regulated requirements of MIL-STD-981B. It is rated for 2.5A at 25°C with a maximum mated height of 0.200 inches. It has an insulation resistance of 1000Mohm with a capability to withstand a voltage of 500V. The operating temperature range for this connector is -65°C to 125°C.

The 91930-21109LF uses a “Cantilever Contact System”. For this system to work, the contact of the connector must first be loaded with a heavy duty adhesive. From there, when the mating part is installed, it presses the cantilever contact which is composed of both spring action and elastic action. This causes the contact to expand which provides a positive retention force. This system is used for very low insertion force and high reliability which ensures a secure connection between contacts.

The 91930-21109LF connector is an ideal choice for a variety of applications, as it offers a high level of performance and reliability. With its robust construction and superior electrical performance, this connector is highly recommended in both commercial and industrial settings.
