Based on your query, **02FST** typically refers to a specific series of **FST (Flexible Printed Circuit to Board)** connectors or a part number prefix used by manufacturers like **JST (Japan Solderless Terminals)**. Below is a breakdown of the electronic specifications and characteristics associated with this part type. --- ## 1. Component Overview The **02FST-BT-KIT** or **02FST-BH** series are Insulation Displacement Connectors (IDC) designed for subminiature applications. They allow for a permanent, solderless connection between a flexible flat cable/circuit and a printed circuit board. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Pitch** | 1.0 mm (0.039") | | **Circuit Count** | 2 Positions (indicated by the "02") | | **Current Rating** | 0.5A AC, DC | | **Voltage Rating** | 50V AC, DC | | **Temperature Range** | -25°C to +85°C | | **Mounting Type** | Through-hole / SMT options | --- ## 2. Physical Construction These parts are engineered for high-density packaging where space is limited. * **Housing Material:** Usually made of heat-resistant Nylon (PA66 or PA46), UL94V-0 rated. * **Contact Material:** Tin-plated Phosphor Bronze. * **Connection Method:** * **IDC (Insulation Displacement):** The cable is pressed into the terminal, which pierces the insulation to create a gas-tight connection. * **ZIF/Non-ZIF:** Most FST parts are non-ZIF, meaning they are soldered directly for a permanent fix rather than acting as a removable socket. --- ## 3. Applications The 02FST series is commonly found in small consumer electronics due to its low profile: 1. **LCD Displays:** Connecting small screens to the main logic board. 2. **Handheld Devices:** Used in cameras and mobile equipment where 2-pin power or signal connections are needed. 3. **Sensors:** Interfacing flexible sensor strips with rigid PCBs. --- ## 4. Identification Code If you are looking at a datasheet, the part number usually breaks down as follows: ```text 02 - FST - BH - (S) | | | | | | | L___ Optional variation (e.g., Side entry) | | L__________ Series Type (e.g., Bottom entry) | L_________________ Series Name (Flexible Staggered Terminal) L________________________ Number of Circuits (2 pins) ``` ---
