The **FF20-15A-R11A** is a specific electronic component manufactured by **DDK Ltd.** It belongs to the category of **FPC (Flexible Printed Circuit) / FFC (Flexible Flat Cable) Connectors**. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications This part is a high-precision connector designed for compact electronic devices where space is limited and high-density wiring is required. | Feature | Specification | | :--- | :--- | | **Manufacturer** | DDK Ltd. | | **Series** | FF20 Series | | **Number of Contacts** | 15 Pins | | **Pitch** | 0.5 mm | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Orientation** | Right Angle (Horizontal) | | **Actuator Type** | ZIF (Zero Insertion Force) - Flip Lock | --- ### 2. Electronic & Material Properties The component is engineered to maintain signal integrity while providing a secure mechanical connection to flexible cables. * **Contact Position:** Bottom Contact (The gold fingers of the FPC cable must face downwards toward the PCB). * **Current Rating:** Typically 0.5A per contact. * **Voltage Rating:** 50V AC/DC. * **Dielectric Withstanding Voltage:** 200V AC (for 1 minute). * **Insulation Resistance:** 500M $\Omega$ minimum. * **Materials:** * **Housing:** LCP (Liquid Crystal Polymer), UL94V-0 rated (Heat resistant for reflow soldering). * **Contacts:** Copper Alloy with Gold plating (to prevent oxidation and ensure low resistance). --- ### 3. Key Design Features * **Low Profile:** The FF20 series is known for its extremely low height (usually around 0.9mm to 1.2mm), making it ideal for smartphones, tablets, and medical wearables. * **ZIF Mechanism:** Uses a rotating "flip-lock" lever. This allows the user to insert the cable with zero friction, then lock it in place to ensure high retention force. * **Cable Thickness:** Designed for FPC/FFC with a standard thickness of **0.2mm**. --- ### 4. Application Areas The FF20-15A-R11A is commonly found in the following hardware: 1. **Mobile Devices:** Connecting LCD screens or touch panels to the main logic board. 2. **Cameras:** Connecting image sensor modules. 3. **Laptops:** Used for keyboard or trackpad ribbon cables. 4. **Automotive:** Infotainment screen connections.
