Applications

The 91615-319 head and mini-card receptacle is used in many applications, such as high-density mobile phones and personal-information systems, handheld computing devices, digital cameras, digital television receivers, hard-disk drives, medical instrumentation, and computer peripherals. It is an ideal replacement for traditional card-edge connectors, particularly when a compact profile and efficient delivery are desired.

Working Principle

The 91615-319 head and mini-card receptacle is a non-floating, surface mount connector designed to mount to two printed circuit boards, interconnecting them securely. It uses a standard edge connector design wherein the contact pins on the mating plug inserts into the contact slots on the header. Contacts are spaced at 0.5mm intervals throughout the contact edge and form a constant electrical connection with the PCB. The edge connector has a self-aligning feature (similar to a card edge connector) which centers the connector on the board when re-mated. The electrical contacts are fully insulated by a plastic or metal covering over the connector.

The 91615-319 is designed for high-performance applications that require low contact resistance and high durability. The connector is manufactured using high-quality gold-plated contact systems, assuring optimal electrical performance and long-term reliability. In addition, the connector’s UL/CSA approval allows it to be used in a variety of equipment.

Conclusion

The 91615-319 head and mini-card receptacle is an ideal choice for applications requiring a small, highly reliable, secure connection between two boards. Its low-profile design, UL94V-0 rating material, and wide operating temperature range ensure that it meets and exceeds industry standards. Its versatile design and UL/CSA approval make it suitable for a wide range of applications.
