The 91900-21421LF is a rectangular connector array specifically designed for multiple circuit board applications. This type of connector carries edge-type flat cables and is suitable for mezzanine-type motherboards. The 91900-21421LF array is an ideal solution for high current applications because it offers sufficient electrical contact level between the two components along with low impedance connections.

The 91900-21421LF has an array of double rows, and each row has fifteen circuits that consist of two parallel contact surfaces. The connector features a high-current rating at 8A and a total mated height of 8.50 mm (±0.50 mm). Its body is manufactured from a UL-rated 94V-0 thermoplastic polyester material, and the contacts are made from high-current, copper alloy. This design maximizes the current carrying capacity of the connector for more reliable connections.

The 91900-21421LF has two mounting styles – a vertical style and a horizontal style. This provides more flexibility in board orientation and allows for the mounting of additional components. The horizontal style of mounting provides a lower profile due to the smaller size of the connectors. The vertical style of mounting provides an open area between the two connectors that can be used to secure additional components or components of a larger size.

The 91900-21421LF array is designed to meet a wide range of applications. Its 8A rating ensures reliable power connections, while its low insertion force makes it easier to connect and remove. The connector offers excellent thermal transfer properties for improved heat dissipation and a wide array of color options for easy identification. It is an ideal solution for applications such as wireless base stations, medical equipment, and instrumentation.

The 91900-21421LF array features an edge-type design that provides a reliable connection interface. The contact surfaces are zinc-plated and the edges are nickel-plated for superior corrosion resistance. The design offers increased contact levels for improved electrical connection and low impedance connections for improved signal integrity.

The working principle of the 91900-21421LF is quite simple. The contacts are designed to make electrical connection through mating of the contact surfaces. This is done by pressing the connector bodies firmly against each other. This ensures that the contact surfaces are properly aligned and that the contacts are making proper electrical connection. The connector is designed to allow for easy installation and removal and to ensure that the connection is secure and reliable.

The 91900-21421LF is an ideal connector for multiple circuit board applications. It offers high current capabilities, low impedance connection, and a wide array of color options. Its edge-type design makes it easy to install and remove and provides a reliable connection interface. The connector also offers a variety of mounting styles to suit different applications and board orientations.
