Based on the technical nomenclature, the **MHO+17FCG-R** refers to a high-precision **TCXO (Temperature Compensated Crystal Oscillator)** typically manufactured by companies like **Mercury Electronic**. Below is a detailed breakdown of its electronic specifications and features. --- ### 1. Technical Specifications The MHO series is known for its high stability and miniature surface-mount design. | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Temperature Compensated Crystal Oscillator (TCXO) | | **Package Type** | SMD (Surface Mount Device) | | **Standard Frequencies** | Often 10MHz to 52MHz (Specific to sub-model) | | **Supply Voltage (Vcc)** | +1.8V to +3.3V DC | | **Frequency Stability** | ±0.5ppm to ±2.5ppm (Over Temp Range) | | **Operating Temperature** | -30°C to +85°C (Standard Industrial) | | **Output Waveform** | Clipped Sine Wave or CMOS | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Part Number Breakdown The alphanumeric code follows a specific logic used by the manufacturer: * **MHO**: Series identifier (High-stability TCXO). * **+**: Usually denotes a specific lead-free or enhanced performance designation. * **17**: Refers to the physical package size (e.g., 7.0 x 5.0 mm or similar standardized miniature footprints). * **FCG**: Internal code for specific temperature stability, voltage, and output type (Clipped Sine is common for this series). * **R**: Indicates **RoHS Compliant** and often refers to "Tape and Reel" packaging. --- ### 3. Key Electronic Features * **Low Phase Noise:** Designed for wireless communication where signal purity is critical. * **Temperature Compensation:** Unlike standard crystals, this part contains an internal compensation circuit that adjusts the frequency based on ambient temperature changes. * **Low Power Consumption:** Optimized for battery-operated devices. * **Clipped Sine Output:** Reduces harmonic distortion and electromagnetic interference (EMI). --- ### 4. Typical Applications This component is used in circuits where timing precision is vital despite environmental temperature fluctuations: 1. **GPS/GNSS Modules:** For accurate satellite signal locking. 2. **Wireless Communications:** Wi-Fi, Bluetooth, and LTE infrastructure. 3. **IoT Devices:** Low-power sensors requiring stable clock references. 4. **Test and Measurement:** Handheld frequency counters or signal generators. --- ### 5.
