The **MHO+72FAG-R** is a specific part number belonging to a series of **Crystal Clock Oscillators** manufactured by **MtronPTI**. These components are critical in electronic circuits for providing a precise and stable timing signal (clock pulse) to microprocessors and digital systems. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the MHO series, here are the technical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | XO (Crystal Oscillator) | Fixed frequency output | | **Package** | 14-pin DIP (DIL) | Through-hole rectangular metal can | | **Output Type** | HCMOS / TTL | Compatible with high-speed CMOS and TTL logic | | **Supply Voltage** | 5.0V | Standard operating voltage | | **Frequency Stability** | ±100 ppm (Typical) | Variance over temperature and time | | **RoHS Status** | -R (Suffix) | Indicates RoHS Compliance (Lead-free) | --- ### 2. Physical Construction The "MHO" series typically utilizes a **Half-Size or Full-Size DIL (Dual-In-Line)** metal package. * **Metal Casing:** Provides electromagnetic interference (EMI) shielding to ensure the clock signal remains clean and does not interfere with other components. * **Hermetic Seal:** The crystal inside is vacuum-sealed to prevent aging caused by moisture or oxidation. --- ### 3. Pin Configuration (Typical 14-pin Full Size) In a standard 14-pin DIP package for oscillators, only 4 pins are usually active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated square wave clock signal | | **14** | Vcc | +5.0V Power Supply | --- ### 4. Common Applications Parts like the MHO+72FAG-R are legacy or industrial-grade components often found in: * **Industrial Control Systems:** Where through-hole components are preferred for durability. * **Legacy Computing:** Motherboards or expansion cards requiring a 5V clock source. * **Telecommunications:** Timing synchronization in networking hardware. * **Test & Measurement Equipment:** Providing a stable reference frequency. --- ### 5. Part Number Breakdown * **MHO:** Series identifier (MtronPTI High-Speed CMOS/TTL). * **7:** Often refers to frequency stability or temperature range (check datasheet for specific code). * **2:** Usually denotes the voltage (5.0V). * **FAG:** Internal factory codes for specific frequency and tuning. * **-R:** RoHS compliant.
