The part number **47LPA-14W0YR-R/Q** typically refers to a specialized **Low-Profile Antennas (LPA)** or a specific **Passive RF Component** (often an Inductor or Filter) produced by manufacturers specializing in surface-mount technology (SMT) for telecommunications. Below is a breakdown of the typical electronic specifications and characteristics associated with this series. --- ## 1. Component Identification | Feature | Description | | :--- | :--- | | **Component Type** | Passive RF Component / Chip Antenna or Inductor | | **Series** | 47LPA (Low Profile Array/Antenna series) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Application** | Wireless communication (Bluetooth, WLAN, ZigBee), IoT devices | ## 2. Technical Specifications While exact specifications can vary by manufacturer (such as Pulse, Ethertronics, or specialized RF vendors), the "14W0" and "YR" suffixes usually denote the following: ### Electrical Characteristics * **Frequency Range:** Typically optimized for the **2.4 GHz to 5.0 GHz** bands (standard for Wi-Fi/Bluetooth). * **Power Rating:** Lower wattage (often indicated by the "W" in the code), suitable for signal processing rather than power transmission. * **Impedance:** Standard **50 Ohms** for RF matching. ### Physical Dimensions * **Low Profile:** Designed for "thin" electronics (smartphones, wearables). * **Form Factor:** Miniature footprint to save PCB real estate. --- ## 3. Part Number Decoding (Typical) Manufacturers often use a logic similar to the one below: | Segment | Meaning | | :--- | :--- | | **47LPA** | Series prefix (47-series Low Profile) | | **14W0** | Physical size or base frequency indicator | | **YR** | Material composition (e.g., Ceramic or Ferrite) | | **-R/Q** | Packaging/Quality code (R = Tape & Reel; Q = Automotive or High Quality) | --- ## 4. Common Applications 1. **Mobile Handsets:** Internal antennas or RF filters for cellular/data bands. 2. **Wearable Tech:** Smartwatches and fitness trackers requiring ultra-small components. 3. **Industrial IoT:** Compact sensor nodes using Zigbee or Sub-GHz protocols. 4. **Automotive:** (If "Q" rated) Infotainment systems or TPMS (Tire Pressure Monitoring Systems). ---
