The **MA65TAG-R** refers to a high-frequency, surface-mount (SMD) RF inductor/tag component, often associated with Murata's "Magicstrap" series or similar RFID/NFC integrated modules. These parts are designed to bridge the gap between traditional PCB manufacturing and RFID functionality. --- ### 1. Key Technical Specifications The "TAG" designation usually implies an integrated circuit (IC) embedded within a ceramic or multilayer substrate that functions as an RFID tag. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | RFID Tag / RF Inductor Module | | **Frequency Range** | 13.56 MHz (HF) or 860-960 MHz (UHF) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Interface** | ISO/IEC 15693 or 18000-63 compatible | | **Packaging** | Tape & Reel (Indicated by the "-R") | | **Operating Temp** | -40°C to +85°C | --- ### 2. Functional Blocks The MA65 series typically integrates several electronic functions into a single 3216 (1206 inch) or smaller package: 1. **Integrated Circuit (IC):** A small silicon die embedded in the substrate containing the memory (EEPROM) and the RF modem. 2. **Impedance Matching Network:** Internal circuitry that matches the IC's impedance to the external antenna traces on the PCB. 3. **Encapsulation:** A rugged ceramic or resin body that protects the delicate silicon during the SMT reflow soldering process. --- ### 3. Application in Circuitry Unlike traditional RFID tags which are stickers, the MA65TAG-R is treated as a standard electronic component. * **Antenna Integration:** The part is soldered onto a PCB where the copper traces of the board act as the RFID antenna. * **Traceability:** It is used primarily for "Board-level Traceability." Manufacturers can track a PCB through the assembly line, testing, and shipping without needing a barcode. * **Memory Access:** It can store serial numbers, firmware versions, or manufacturing dates that can be read wirelessly even if the device is powered off. --- ### 4. Part Number Breakdown While specific to the manufacturer's nomenclature, the suffix generally follows this logic: * **MA65:** Series identifier (Physical size and base technology). * **TAG:** Indicates it is a functional RFID tag rather than a passive inductor. * **-R:** Indicates the packaging format is **Tape & Reel**, intended for automated pick-and-place machines. ---
