The **FJT-06-R** is an electronic component primarily classified as a **Phone Jack / Audio Connector**. It is commonly used in consumer electronics for audio signal transmission, such as connecting headphones, microphones, or speakers. --- ## 1. Technical Specifications The FJT-06-R is a standardized female jack, typically featuring the following electrical and mechanical characteristics: | Property | Description | | :--- | :--- | | **Connector Type** | 3.5mm (1/8") Phone Jack | | **Mounting Type** | Through-hole (PCB Mount) | | **Number of Poles** | 3-Pole (Stereo: Left, Right, Ground) | | **Contact Resistance** | ≤ 30mΩ | | **Insulation Resistance** | ≥ 100MΩ at 500V DC | | **Voltage Rating** | 12V DC - 34V DC (typical range) | | **Current Rating** | 0.5A - 1A | | **Insertion Force** | 3N - 20N | --- ## 2. Pin Configuration and Functions The "06" in the series often refers to the specific pinout configuration. For a standard 3.5mm stereo jack like this, the pins usually correspond to: 1. **Sleeve (S):** Ground/Common. 2. **Tip (T):** Left Channel signal. 3. **Ring (R):** Right Channel signal. 4. **Shunt/Switch Pins:** Some versions include "Normally Closed" switches that disconnect internal speakers when a plug is inserted. --- ## 3. Physical Construction The part is engineered for durability and signal integrity through specific material choices: * **Housing:** High-temperature thermoplastic (e.g., PBT or Nylon) to withstand wave soldering. * **Contacts:** Phosphor bronze or brass, usually plated with **Nickel** or **Gold** to prevent oxidation and ensure low contact resistance. * **Orientation:** Right-angle (horizontal) mounting is the most common form factor for this part, allowing it to sit flush with the edge of a device's casing. --- ## 4. Common Applications * **Audio Interfaces:** Sound cards and external DACs. * **Portable Electronics:** MP3 players, handheld gaming consoles, and radios. * **Communication Devices:** Intercom systems and walkie-talkies. * **DIY Electronics:** Breadboard-friendly breakout modules for Arduino or Raspberry Pi projects.
