Key Technical Specifications | Feature | Specification Details | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (Fixed) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Voltage Supply** | Typically 5.0V (Standard for MHO series) | | **Frequency Range** | Varies by sub-model (Check specific markings for MHz) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the manufacturing standards and physical properties: * **MHO**: Represents the Series (MtronPTI High-reliability Oscillator). * **+**: Often signifies a specific lead-free or improved processing version. * **12**: Refers to the frequency stability (typically ±100ppm or ±50ppm depending on the datasheet revision). * **F**: Refers to the Symmetry/Duty Cycle (usually 40/60% or 45/55%). * **A**: Temperature Range (Standard Commercial or Industrial). * **G**: Output Load (usually 15pF or 50pF). * **-R**: **RoHS Compliant**. This confirms the part is manufactured without hazardous substances like lead. --- ### 3. Pin Configuration (Full-Size DIP) Since this is a 4-pin device housed in a 14-pin footprint, the connections are standard: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC / Tri-state | No Connection or Output Enable/Disable | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated clock signal (Square wave) | | **Pin 14** | Vcc | Positive Power Supply (+5V) | --- ### 4. Typical Applications The MHO+12FAG-R is designed for "through-hole" mounting on Printed Circuit Boards (PCBs). It is commonly found in: * **Legacy Computing:** Motherboards and peripheral controllers. * **Industrial Control:** PLCs and automation timing. * **Networking:** Routers and switches requiring a stable 5V clock source. * **Testing Equipment:** Signal generators and measurement tools.
