The **MHO+15TAD-R** is a high-precision electronic component belonging to the **Crystal Oscillator** category. Specifically, it is a TCXO (Temperature Compensated Crystal Oscillator) or a high-stability clock oscillator often used in telecommunications and industrial timing applications. --- ### 1. General Specifications The part number follows a specific nomenclature used by manufacturers (typically **MtronPTI**). Here is a breakdown of its technical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (SPXO/TCXO series) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full size | | **Input Voltage (Vcc)** | Typically +5.0V DC | | **Output Type** | CMOS / TTL Compatible | | **Frequency Stability** | Generally ±25ppm to ±100ppm (depending on grade) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the -R suffix) | --- ### 2. Pin Configuration Since this is a standard 14-pin DIP package oscillator, it usually utilizes only four of the 14 pins, while the others are removed or not connected (NC). | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit and Case Ground | | **8** | Output | The generated frequency signal | | **14** | Vcc | +5.0V Power Supply | --- ### 3. Key Features * **Through-Hole Design:** The "MHO" prefix typically refers to the metal "Half-Size" or "Full-Size" DIP package, which provides excellent EMI shielding. * **Stability:** Designed to maintain a consistent frequency even when the ambient temperature fluctuates. * **Reliability:** The hermetically sealed metal case protects the internal quartz crystal from humidity and atmospheric contaminants. * **Legacy Support:** Frequently used in older industrial equipment, networking hardware, and test instruments that require a robust 5V clock source. --- ### 4. Part Number Decoding The suffixing usually follows this logic: * **MHO:** Series identifier (Metal Hermetic Oscillator). * **15:** Often refers to the stability or voltage variant (e.g., 5V). * **TAD:** Specific internal calibration or temperature range code. * **-R:** RoHS (Restriction of Hazardous Substances) compliant/Lead-free. ---
