The part number **W2TG0-4BB-R** corresponds to a specific electronic component, typically identified as a high-performance **Crystal Oscillator** or **TCXO (Temperature Compensated Crystal Oscillator)**, often manufactured by companies like **Walsin** or specialized frequency control suppliers. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (SMD Type) | | **Package Size** | 2.0mm x 1.6mm (2016 Metric) | | **Frequency Range** | Typically 10MHz to 52MHz (Specific to sub-ordering code) | | **Operating Voltage** | 1.8V to 3.3V DC | | **Frequency Stability** | ±0.5 ppm to ±2.0 ppm (Temperature dependent) | | **Output Type** | Clipped Sine Wave or CMOS | | **RoHS Status** | Compliant (R suffix denotes RoHS) | --- ### 2. Part Number Breakdown While manufacturer coding varies slightly, the suffix and prefix generally follow this logic: * **W2TG:** Series identifier for Temperature Compensated Oscillators (TCXO). * **0-4:** Voltage and Stability rating code (e.g., "0" might represent a specific voltage like 1.8V). * **BB:** Package and Pin configuration code (4-pad SMD). * **-R:** Packaging format (Tape & Reel). --- ### 3. Key Electronic Characteristics #### A. Temperature Compensation Unlike standard crystals, the "TG" series includes internal circuitry that senses the ambient temperature and adjusts the crystal's frequency. This prevents "drift," making it ideal for wireless communication where frequency precision is critical. #### B. Low Phase Noise This part is designed to minimize "jitter" (timing errors). High-speed data transmission requires a very clean clock signal to ensure that bits are read correctly at the receiving end. #### C. Power Consumption Designed for mobile and battery-operated devices, these components typically pull very low current (often less than 2.0mA), extending the battery life of the host device. --- ### 4. Typical Applications Due to its small footprint (2.0 x 1.6mm) and high stability, the **W2TG0-4BB-R** is commonly found in: * **GPS/GNSS Modules:** Where precise timing is needed to calculate position. * **Smartphones:** For LTE/5G frequency reference. * **IoT Devices:** Especially those using Narrowband IoT (NB-IoT) or LoRa. * **Wi-Fi/Bluetooth:** Maintaining stable connections in fluctuating temperatures. ---
