The **MHO+34FDD-R** is a specific part number typically associated with a **Crystal Oscillator**. While the prefix "MHO" is often used by manufacturers like *MtronPTI* or other timing component specialists, this specific code refers to a high-reliability, through-hole electronic component used for generating precise clock signals. --- ### 1. Key Technical Specifications Below is a breakdown of the typical characteristics for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package / Case** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | 5.0V (Standard for "MHO" series) | | **Frequency Stability** | ±100ppm to ±25ppm (depending on suffix) | | **Operating Temperature** | 0°C to +70°C (Standard) or -40°C to +85°C | | **Mounting Type** | Through-Hole | --- ### 2. Part Number Breakdown The alphanumeric string usually follows a specific manufacturer nomenclature: * **MHO:** Series identifier (Metal Hybrid Oscillator). * **3:** Represents the Supply Voltage (often 5.0V in this older nomenclature). * **4:** Accuracy/Stability code (often denotes ±50ppm or ±100ppm). * **FDD:** Specific internal configuration (Duty cycle, Enable/Disable function). * **R:** RoHS Compliant (Lead-free). --- ### 3. Pinout Configuration For a standard 14-pin DIP package (though only 4 pins are physically present), the layout is usually: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Tri-state Enable | | **7** | GND | Circuit Ground | | **8** | Output | The generated frequency signal | | **14** | Vcc | +5.0V DC Supply | --- ### 4. Applications This part is commonly found in legacy industrial hardware and specific communication equipment where robust through-hole mounting is preferred over surface-mount (SMD) alternatives. * **Microprocessor Clocks:** Providing the heartbeat for CPUs. * **Embedded Systems:** Timing for logic gates and FPGAs. * **Industrial Controllers:** Used in environments where vibration resistance (through-hole) is required. ---
