The 71249-0550LF is one of the memory connectors from the PC card socket family. It integrates two 72-pin contact lines to permit 2-row connection, and dissipates interference with the help of ground labels on all four sides. This memory connector is designed for accommodating Type II PCMCIA and CardBus PC cards used in devices such as notebook computers, mobile phones, and card readers.

The 71249-0550LF utilizes a push-pull ejector that allows easier insertion and extraction of PC cards and comes with a metal card ejector that eliminates the need for a separate tool for card removal. It also has two-corner protection that guards against card damage by keeping it securely in place//allowing for usage with one card only. This memory connector is constructed with an electroless nickel plating on all contact surfaces, which ensures greater contact integrity, prolonged electrical life, and high resistance to corrosion.

In terms of its application field, the 71249-0550LF is ideal for applications that require reliable connection and efficient power consumption. Its features allow it to be used in high-density connectors and high-performance applications with minimal crosstalk, making it ideal for 2-row connection of Type II PCMCIA and CardBus PC cards. Further, this memory connector is compatible with most of the widely used portable devices and storage cards, making it an ideal choice for the increasingly mobile lifestyle.

The 71249-0550LF uses a contact alignment insert to ensure reliable connections and prevent potential damage to the device\'s primary circuit board or memory card. It extends insulation through the area between the two contact lines, ensuring greater protection against short circuits. Further, it uses a dual-footprint design to ensure a secure fit with various devices, ensuring a great level of system and operational integrity.

In terms of its working principle, the 71250-0550LF utilizes two contact lines connected to a single PCMCIA/CardBus card. When the card is inserted, two stainless steel leaf springs positioned on opposite sides of the socket make contact with the card\'s contact pads. This connection ensures proper power and data flow from the card to the PC. The connection also ensuresthat the primary power circuit board remains protected from potential damage.

Following proper insertion, the 71250-0550LF uses electrostatic discharge (ESD) protection to guard against potential interference. An EMI finger shield integrated into the device blocks out any external electromagnetic interference and ensures that the performance and data integrity of the connection is maintained. Further, the socket also features an integrated plastic fusing system that triggers if an incorrect voltage or over-current is detected, automatically disconnecting the device for protection.

All in all, the 71250-0550LF offers a reliable and efficient connection for two-row PCMCIA and CardBus only applications. It comes with an advanced contact alignment insert, push-pull ejector, ground label, ESD protection, and plastic fusing system, all of which help ensure a secure and reliable connection. This memory connector is ideal for applications that require a high-performance solution and power efficiency.
