Flat Flexible Connectors (FFC, FPC) are compact, lightweight, and robust connectors used in various applications. They are widely used in the consumer electronics, automotive, medical, and aerospace industries. This article reviews the application field and working principle of an FFC/FPC connector, SFW19R-2STE1.

Overview of FFC/FPC Connectors

FFC/FPC connectors are a type of single-in-line connectors with contact counts between 5 and 1000. They are composed of a single- or double-sided flexible flat circuit (FFC) or flexible printed circuit (FPC), and a single- or double-sided plastic shield. These components are held together using a compression fitting system which provides strain relief, holding the components in place. FFC/FPC connectors are available in 1.2mm and 1.25mm pitches.

FFC/FPC connectors offer a range of advantages, including:

• A small overall size which allows them to be used in compact, space saving designs
• Lightweight, reducing the overall weight of a product or PCB
• High contact density, allowing an increased number of connections with minimal space
• Ease of assembly, with a simple, straightforward design
• Resistance to shock, vibration, and corrosion

Features and Specifications of the SFW19R-2STE1

The SFW19R-2STE1 is an FFC/FPC connector from Samtec. It features a low profile, height of only 6.1mm, and a narrow footprint, width of only 6.15mm. The contacts are 1.25mm pitch, and the contact count is 100. It is rated for a current capacity of 0.5A per contact and a voltage capacity of 30V AC/DC.

The connector has a durable, gold-plated contact system which provides resistance to shock, vibration, and corrosion. The shield is made of a UL 94V-0 rated plastic material for added rigidity and strength. The connector also features Samtec\'s patented push-pull mating system, which allows for easy, one step mating. It has a low insertion force and insertion cycle life of 10,000 times or more.

Application Fields and Working Principle of the SFW19R-2STE1

The SFW19R-2STE1 is a general-purpose FFC/FPC connector which can be used in a wide range of applications, including consumer electronics, automotive, medical, and aerospace. It is used to connect two circuit boards or devices together, as an interconnect solution. The FFC/FPC cable is connected to each board, and the connector is used to hold the cable securely in place.

The connector works by having pins on the housing of the connector which align with the holes in the FFC/FPC cable. This creates an electrical connection between the two circuit boards, allowing data and/or power to be transferred across the connection. The connector also has a locking tab which holds the cable in place, providing a secure connection.

Conclusion

The SFW19R-2STE1 FFC/FPC connector from Samtec is a robust, reliable connector which can be used in a wide range of applications. It features a 1.25 mm pitch, current capacity of 0.5A per contact, and a voltage capacity of 30V AC/DC. It is also has a low profile, height of only 6.1mm, a narrow footprint, width of only 6.15mm, and a patented push-pull mating system for easy one-step mating. This connector is ideal for consumer electronics, automotive, medical, and aerospace applications.
