The **MHO+16FAG-R** is a specific series of high-precision, high-frequency **Crystal Oscillators** manufactured by **Mercury Electronic**. These components are essential for providing a stable clock signal in digital circuits. --- ### 1. Technical Specifications The "MHO" series typically refers to Metal-Can (DIP-14 or DIP-8 style) oscillators known for their durability and EMI shielding. | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | 5.0V (Standard for MHO series) | | **Frequency Stability** | ±25ppm to ±100ppm | | **Operating Temperature** | -10°C to +70°C (Standard) | | **RoHS Status** | Compliant (Indicated by -R) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the exact characteristics of the component: * **MHO**: Series designation (Mercury High Output/Metal Housing). * **+**: Often indicates a specific voltage or lead-free process enhancement. * **16**: Refers to the fundamental frequency (e.g., **16.000 MHz**). * **FAG**: Internal factory codes for frequency stability, temperature range, and duty cycle (usually 50% ±10%). * **-R**: Indicates **RoHS Compliant** (Lead-free). --- ### 3. Pin Configuration (DIP-14 Package) Standard crystal oscillators in this form factor use a 4-pin connection layout within a 14-pin footprint: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | Clock Signal Output | | **14** | Vcc | Power Supply (+5V) | --- ### 4. Key Features & Applications * **Metal Shielding:** The metal casing reduces electromagnetic interference (EMI), making it ideal for sensitive radio or measurement equipment. * **Reliability:** Through-hole mounting (DIP) provides high mechanical stability compared to surface mount (SMD) in high-vibration environments. * **Applications:** * Microprocessor clocking. * Embedded systems. * Industrial control boards. * Legacy computer hardware maintenance. ---
