The **MHO+18FAAG-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like **Mercury Electronic**. These components are critical for providing a stable clock signal in digital circuits. --- ## 1. Component Overview The MHO series generally refers to high-stability, metal-can (DIP-14 or DIP-8 style) oscillators. They are active components, meaning they require a power supply to generate a square wave output. ### Technical Specifications | Feature | Specification (Typical) | | :--- | :--- | | **Package Type** | DIP-14 (Full size) or DIP-8 (Half size) Metal Can | | **Frequency Range** | Usually 1.0 MHz to 100 MHz (Varies by sub-model) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | 5.0V (Standard for '+' series) | | **Operating Temperature** | -10°C to +70°C (Standard commercial grade) | | **RoHS Status** | Compliant (Indicated by '-R') | --- ## 2. Key Features * **High Stability:** Metal-can packaging provides excellent EMI shielding and physical protection. * **Integrated Circuitry:** Unlike a passive crystal, this part includes the oscillation circuit and a buffer internally. * **Low Jitter:** Designed for timing-critical applications like microprocessors and data communication. * **Through-Hole Mounting:** The "FAAG" suffix often points to specific lead lengths and mounting styles suitable for PCB through-hole assembly. --- ## 3. Pin Configuration (DIP-14 Style) Most MHO series oscillators follow a standard industrial pinout for 4-pin metal cans: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Positive power supply (+5V) | --- ## 4. Common Applications * **Microcontrollers:** Providing the external clock source for high-speed MCUs. * **Networking:** Timing for Ethernet controllers or routers. * **Industrial Control:** Stable pulse generation for PLC systems. * **Legacy Hardware:** Often found in older computing hardware or specialized lab equipment. ---
