Rectangular connectors are some of the most commonly used connectors in our lives, particularly in the electronics industry. The 91901-32169LF is a mezzanine board-to-board connector, a type of rectangular connector. The application fields and working principle of 91901-32169LF are elaborated in this article.

Application Fields

The 91901-32169LF is primarily used as a mezzanine connector to enable communication between two printed circuit boards. It is especially useful for short-range communication between PCBs like embedded boards. This includes mission-critical systems, autonomous cars, medical imaging, industrial automation, and various IoT devices.

Apart from communication, 91901-32169LF can also be used for power delivery between two PCBs. Its high pin count, low profile design, and large contact area make it well-suited for applications where PCBs have high pin densities. With the help of 91901-32169LF, more power can be delivered into a smaller area while meeting the safety requirements of the International Organization for Standardization (ISO).

In addition, being a low profile connector, 91901-32169LF is a great choice for slender PCBs. It is suitable for applications where boards are placed in tight spaces and minimal space is available for connectors. This includes USB-based applications, smartphones, wearables, laptops, and smartwatches.

Working Principle

The 91901-32169LF works on the same principle as any other board-to-board connector. When two PCBs are connected using 91901-32169LF, the connector allows for two-way communication between them. It has two rows of pins which form a V-shape, and the pins on the two sides of the V-shape are in direct contact with the PCBs.

The 91901-32169LF has two unique features which make it stand apart from the other connectors in its class. Firstly, it has an upturned SMT pin design which eliminates the transition impedance problem of through-hole designs and ensures signal integrity. Secondly, it has a double-row design which allows the contacts to be clamped in the PCB more securely.

Besides this, 91901-32169LF also uses a strong, press-fit retention force to keep the connector firmly in place. This ensures reliable contact between the pins and the PCBs, which minimizes signal loss due to vibration. Furthermore, it has a secure locking mechanism which prevents accidental disconnection.

In conclusion, 91901-32169LF is an ideal choice for short-range communication between two PCBs. Its wide-range of applications, ease of installation, and secure locking mechanism make it a great choice for applications ranging from embedded systems to wearables.
