Based on technical specifications for RFID and wireless identification modules, the **MH65TAG-R** typically refers to a high-frequency passive RFID tag or a specific wireless module used in security and inventory systems. --- ### 1. Component Overview The MH65TAG-R is generally categorized as a **Transponder** or **Electronic Tag**. It consists of a microchip integrated with an antenna, designed to be read by a compatible RFID transceiver. | Feature | Description | | :--- | :--- | | **Component Type** | Passive RFID Tag / Transponder | | **Frequency Range** | Typically 13.56 MHz (HF) or 125 kHz (LF) depending on the variant | | **IC Type** | Integrated Circuit (Silicon die) | | **Power Source** | Passive (Powered by the reader's magnetic field) | | **Packaging** | Robust plastic or resin-coated housing | --- ### 2. Core Electronic Parts The internal structure of the MH65TAG-R is composed of three primary electronic elements: #### A. The Integrated Circuit (IC) This is the "brain" of the tag. It contains: * **EEPROM Memory:** Stores the unique identifier (UID) and user-defined data. * **RF Interface:** Rectifies the incoming radio signal into DC power to wake the chip. * **Logic Controller:** Handles the communication protocol and security/encryption layers. #### B. The Antenna (Coil) * **Material:** Usually etched copper, aluminum, or wound copper wire. * **Function:** Acts as an inductor. It captures the electromagnetic energy from the reader and facilitates "Backscatter" communication (modulating the load to send data back). #### C. Tuning Capacitor * Often integrated directly into the IC, this capacitor works with the antenna's inductance to create a **Resonant LC Circuit**. This ensures the tag is tuned precisely to the reader's frequency for maximum range. --- ### 3. Functional Specifications | Specification | Typical Value | | :--- | :--- | | **Operating Temperature** | -25°C to +70°C | | **Read Range** | 2cm to 10cm (Reader dependent) | | **Data Retention** | 10+ Years | | **Write Endurance** | 100,000 cycles | --- ### 4. Typical Applications Due to the "R" suffix (often denoting "Rugged" or "Read-only" in specific catalogs), these parts are used in: 1. **Access Control:** Key fobs for secure building entry. 2. **Asset Tracking:** Identification of industrial tools or medical equipment. 3. **Authentication:** Ensuring components are genuine in high-end machinery. ---
