The **MHO+14TBD-R** is a specific type of **Crystal Oscillator** manufactured by MtronPTI. It is part of the MHO series, which are high-reliability, through-hole clock oscillators commonly used in industrial and legacy computing systems. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) | | **Output Type** | HCMOS / TTL Compatible | | **Voltage Supply** | Typically 5.0V DC | | **Frequency Stability** | ±100 ppm (Standard for this series) | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ## 2. Pin Configuration Although it is a "14-pin" package, most of the pins are removed for internal circuitry, leaving 4 active pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit and Case Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | +5.0V Power Supply | --- ## 3. Key Features * **Through-Hole Design:** The 14-pin DIP footprint allows for easy soldering onto printed circuit boards (PCBs) or insertion into sockets for prototyping. * **Hermetically Sealed:** The metal "can" is resistance-welded to protect the quartz crystal from atmospheric moisture and contaminants, ensuring long-term frequency stability. * **Legacy Compatibility:** These are often used as drop-in replacements for older 5V timing circuits where modern surface-mount (SMD) components are not applicable. --- ## 4. Application Areas The MHO series is generally found in: 1. **Microprocessor Clocks:** Providing the master heartbeat for CPUs. 2. **Data Communications:** Timing for serial ports and network interfaces. 3. **Industrial Controls:** Used in PLC (Programmable Logic Controller) boards. 4. **Test Equipment:** General-purpose frequency generation in lab gear. ---
