The **MHO+12FBG-R** is a specific part number typically associated with **crystal oscillators** (XO), specifically high-precision timing components used in telecommunications and data networking. --- ### 1. General Specifications Based on the standard nomenclature for this series (often produced by manufacturers like MtronPTI), here is a breakdown of the technical characteristics: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Frequency Range** | Typically fixed (Check specific datasheet for exact MHz) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | Usually 3.3V or 5.0V (indicated by the "+" or "12" prefix) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) Metal Can | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown The alphanumeric code provides specific details about the component's construction and tolerances: * **MHO**: Represents the series (Metal Thru-Hole Oscillator). * **+**: Often indicates a 3.3V operation (Positive voltage logic). * **12**: Refers to the stability/frequency tolerance (e.g., ±100ppm or ±50ppm depending on the manufacturer's specific code table). * **F**: Frequency stability code (often denotes Industrial temperature range). * **B**: Output symmetry/Duty cycle (usually 40/60% or 45/55%). * **G**: Tri-state Enable/Disable function on Pin 1. * **-R**: RoHS Compliant (Lead-free). --- ### 3. Pin Configuration The MHO series usually follows the standard 14-pin DIP "Full Size" layout, though only 4 pins are physically present: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Tri-state Control (Enable/Disable) | | **7** | GND | Case Ground | | **8** | Output | Frequency Square Wave Output | | **14** | Vcc | Supply Voltage (Power) | --- ### 4. Typical Applications These oscillators are designed for high-reliability environments where timing precision is critical: * **Networking Gear:** Routers, switches, and bridges. * **Industrial Control:** PLCs and automation timing. * **Legacy Computing:** Motherboards or embedded systems requiring a clock source. * **Test Equipment:** Oscilloscopes and signal generators. --- ### 5. Key Electrical Precautions When integrating this part into a circuit: 1. **Decoupling:** Place a **0.01µF to 0.1µF capacitor** as close to the Vcc (Pin 14) and GND (Pin 7) as possible to filter noise. 2. **Load Capacitance:** Ensure the load on the output pin does not exceed the specified pF (usually 15pF to 50pF) to avoid signal distortion. 3. **Soldering:** Metal can oscillators are sensitive to prolonged heat; use standard wave soldering or hand soldering profiles.
