FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors (FFCs) and Flexible Printed Circuits (FPCs) are specialized ribbon cables used to interconnect electronic components. FFCs and FPCs have a number of design advantages, including reduced board area requirements and improved electrical performance over larger connectors, as well as their ability to attach to more complex terminal designs. One example of an FFC that exemplifies these advantages is the SFV35R-3STBE1HLF. This connector is designed for a wide range of applications, from simple low voltage signals to high power applications.

Applications

The SFV35R-3STBE1HLF is a small, flexible connector that can be used in a variety of applications. It features two rows of 3.5mm pitch contacts, making it suitable for applications where space is limited or a small number of contacts is required. The connectors are rated for operating voltages up to 2A and current up to 75V, allowing them to be used for low voltage signals as well as high power applications. Additionally, the connector is RoHS compliant, making it an ideal choice for applications in which RoHS compliance is required.

Design Options

The SFV35R-3STBE1HLF connector is available in both straight and right angled configurations. The connector is designed to accommodate either straight or right-angle contact entry depending on the application requirements, allowing the user to select the appropriate design for their needs. Additionally, the connector is available with both male and female contacts and is suitable for both wave and reflow soldering.

Working Principle

The SFV35R-3STBE1HLF connector uses a flat flexing contact design, which ensures that the contacts remain securely connected even when the connector is flexed. This is accomplished through the use of flat flexing pads on the contact assembly, which are designed to provide the necessary flexibility and elasticity while still ensuring that the contact remains firmly secured to the PCB. Additionally, the flat flexing contacts feature a spring-loaded terminal design, which further increases the contact\'s reliability and ensures that the contacts remain securely connected even when subjected to vibration or shock.

Conclusion

The SFV35R-3STBE1HLF is an ideal connector for a wide range of applications due to its small size, high reliability, and RoHS compliance. This connector is available in both straight and right angle configurations and is compatible with both wave and reflow soldering. Additionally, the SFV35R-3STBE1HLF features flat flexing contact technology, which provides the necessary flexibility and elasticity to ensure a secure connection even when the connector is flexed. This versatile connector is an ideal choice for both low voltage and high power applications.
