Based on the product code provided, the **MHO+38TFG-R** typically refers to a high-precision, temperature-compensated crystal oscillator (TCXO) or a specific series of clock oscillators often manufactured by companies like **Mercury Electronic**. Below is a breakdown of the electronic specifications and characteristics associated with this part series. --- ## 1. Component Overview The **MHO+** series is designed for high-stability timing applications. These components are used to provide a precise frequency reference for digital circuits, telecommunications, and industrial equipment. ### Key Specifications Table | Feature | Typical Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (Clock) | | **Package Style** | 14-pin DIP (Thru-hole) - often "Half Size" or "Full Size" | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | 3.3V or 5.0V (Standard) | | **Frequency Stability** | ±25ppm to ±100ppm (Depending on grade) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ## 2. Part Number Breakdown While manufacturer coding can vary slightly, the suffix codes generally represent the following: * **MHO+**: The series identifier (Metal Can, High-Output/High-Stability). * **3**: Often denotes the supply voltage (e.g., 3.3V). * **8**: Can refer to frequency stability or specific symmetry requirements. * **TFG**: * **T**: Usually indicates "Tight" stability or a specific Temperature range. * **F**: Often denotes "Full Size" or a specific pinout configuration. * **G**: Typically stands for **Gold plated** leads or a specific RoHS compliance marker. * **R**: Generally indicates **RoHS Compliant**. --- ## 3. Physical & Functional Features ### Connectivity (Pinout) For the 14-pin DIP package (where only 4 pins are usually present): 1. **Pin 1**: NC (No Connection) or Tri-state Control (Enable/Disable). 2. **Pin 7**: Ground (Case). 3. **Pin 8**: Output (Frequency signal). 4. **Pin 14**: Vcc (Supply Voltage). ### Applications * **Networking**: Routers, switches, and modems. * **Industrial**: PLC controllers and embedded systems. * **Legacy Systems**: Replacement parts for older motherboards or radio equipment requiring a 14-pin DIP footprint. --- ## 4. Technical Precautions When integrating this part into a circuit, consider the following: ```markdown 1. Decoupling: Place a 0.01µF to 0.1µF capacitor close to Vcc (Pin 14) to filter noise. 2. Loading: Ensure the load capacitance (CL) matches the datasheet (usually 15pF or 30pF). 3. Soldering: Observe wave soldering profiles to avoid thermal shock to the internal crystal. ```
