The **FF0881SA1-R3000** is a high-precision, low-profile electronic connector manufactured by **JAE (Japan Aviation Electronics Industry)**. It is primarily used in compact portable electronics to connect Flexible Printed Circuits (FPC) to the mainboard. --- ### 1. Technical Specifications The following table highlights the core technical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector Type** | FPC Connector | | **Number of Contacts** | 81 Positions | | **Pitch** | 0.2 mm (Fine Pitch) | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Actuator Type** | Front Flip (Easy-On) | | **Height** | 0.9 mm (Low Profile) | | **Current Rating** | 0.2 A per contact | | **Voltage Rating** | 50 V AC/DC | | **Contact Resistance** | 100 mΩ Max | --- ### 2. Key Design Features * **Ultra-Fine Pitch:** At **0.2 mm**, it is designed for high-density routing, allowing 81 connections in an extremely small footprint. * **Bottom Contact Point:** The electrical interface is located on the bottom of the connector, meaning the FPC leads must face downward when inserted. * **Space Saving:** The 0.9 mm height makes it ideal for thin devices like smartphones, tablets, and wearable medical sensors. * **Cable Lock Mechanism:** Features a locking lever (actuator) that provides a tactile "click" to ensure the FPC is securely seated and prevents accidental disconnection due to vibration. --- ### 3. Common Applications Due to its high pin count and miniature size, the FF0881SA1-R3000 is typically found in: 1. **Mobile Devices:** Connecting high-resolution LCD/OLED displays or camera modules. 2. **Wearables:** Smartwatches and fitness trackers where internal volume is extremely limited. 3. **Medical Imaging:** Handheld ultrasound or diagnostic tools. 4. **High-End Laptops:** Ultra-thin "ultrabooks" for keyboard or trackpad connections. --- ### 4. Handling Precautions Because of the **0.2 mm pitch**, this part is highly sensitive: * **Alignment:** Precise alignment is required during the SMT soldering process to avoid solder bridging. * **Fragility:** The front-flip actuator is delicate; excessive force during opening or closing can snap the plastic housing. * **Cleanliness:** Dust or skin oils on the FPC gold fingers can significantly impact the 100 mΩ contact resistance.
