The **FF20-11A-R11A** is a specialized electronic component, specifically an **FPC (Flexible Printed Circuit) Connector**. It is manufactured by **DDK (Dai-Ichi Denshi Kogyo)** and is designed for high-density, low-profile electronic applications. --- ### 1. Key Technical Specifications The following table outlines the primary physical and electrical characteristics of the connector: | Feature | Specification | | :--- | :--- | | **Connector Type** | FPC (Flexible Printed Circuit) Connector | | **Number of Pins** | 11 Positions | | **Pitch** | 0.5 mm | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Orientation** | Right Angle | | **Actuator Type** | ZIF (Zero Insertion Force) Flip-Lock | | **Contact Location** | Bottom Contact | | **Current Rating** | 0.5 A per contact | | **Voltage Rating** | 50V AC (rms) | --- ### 2. Design and Construction The "FF20" series is characterized by its compact form factor, making it ideal for devices where internal space is extremely limited. * **ZIF Mechanism:** It uses a Zero Insertion Force mechanism, meaning the flexible cable can be inserted without friction. The "flip-lock" or "slider" is then engaged to secure the connection. * **Contact Point:** This specific model is a **bottom-contact** type, meaning the gold-plated fingers of the FPC cable must face downwards toward the PCB to make an electrical connection. * **Material:** The housing is typically made of heat-resistant plastic (LCP) to withstand SMT reflow soldering temperatures. --- ### 3. Common Applications Due to its 0.5mm pitch and 11-pin configuration, this part is frequently found in: 1. **Handheld Electronics:** Digital cameras, smartphones, and handheld gaming consoles. 2. **Display Modules:** Connecting LCD or OLED screens to the main logic board. 3. **Optical Drives:** Used in slim laptops or portable disc players. 4. **Medical Devices:** Small-scale diagnostic tools and sensors. --- ### 4.
