The **MA13TAG-R** is a specific electronic component typically categorized as a **Micro-Antenna** or a **NFC/RFID Tag Module**. These parts are commonly used in short-range wireless communication applications. --- ### 1. General Specifications The MA13 series is often associated with miniature RFID (Radio Frequency Identification) components designed for high-frequency (HF) bands. | Feature | Description | | :--- | :--- | | **Component Type** | RFID / NFC Transponder Tag | | **Frequency** | 13.56 MHz (High Frequency) | | **Mounting Type** | Surface Mount (SMD) / Embedded | | **Shape/Form Factor** | Miniature rectangular or circular tag | | **Compliance** | ISO/IEC 14443 Type A or ISO 15693 (depending on internal IC) | --- ### 2. Key Electronic Characteristics The "R" suffix usually denotes a specific packaging type (like Tape & Reel) or a revision involving a specific resonant frequency calibration. * **Resonant Frequency:** Tuned to **13.56 MHz**, which is the global standard for NFC. * **Inductance:** The part contains a precision-wound micro-coil that acts as an antenna. * **Memory/IC:** Usually contains a small EEPROM (e.g., 1k to 4k bits) for storing unique identification (UID) and user data. * **Passive Operation:** It is a **passive** component, meaning it has no battery. It derives power from the electromagnetic field generated by an RFID reader. --- ### 3. Application Use Cases Due to its small size, the MA13TAG-R is used in environments where space is highly constrained. * **Asset Tracking:** Tracking small medical instruments or laboratory samples. * **Authentication:** Verifying the authenticity of high-value consumables (e.g., printer cartridges, luxury goods). * **Access Control:** Integration into small key fobs or wearable devices. * **IoT Nodes:** Providing a "Touch-to-Pair" interface for Bluetooth or Wi-Fi devices. --- ### 4.
