The **MHO+11FBD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like **Mercury Electronic**. These components are essential for providing a stable clock signal in digital circuits. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the MHO series, here are the general technical parameters: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | DIP-14 (Full size) or DIP-8 (Half size) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | Typically 5.0V (Standard for MHO series) | | **Operating Temperature** | -10°C to +70°C (Standard Commercial) | | **Frequency Stability** | ±100ppm, ±50ppm, or ±25ppm (depending on suffix) | | **RoHS Status** | "R" suffix usually denotes RoHS Compliance | --- ### 2. Part Number Breakdown Understanding the alphanumeric code helps identify the exact characteristics of the component: * **MHO**: Represents the Series Name (Metal Hollow-package Oscillator). * **11**: Usually refers to the voltage and stability combination (e.g., 5.0V operation). * **F**: Often designates the frequency stability or specific output symmetry (e.g., 45/55%). * **BD**: This usually refers to the specific pinout configuration or the package dimensions (DIP-14 style). * **-R**: Indicates **RoHS Compliant** (Lead-Free). --- ### 3. Physical Construction These parts are housed in a hermetically sealed metal "can" package. This design provides several benefits: 1. **Shielding:** The metal casing acts as a Faraday cage, reducing Electromagnetic Interference (EMI). 2. **Durability:** The rigid pins are designed for through-hole mounting on Printed Circuit Boards (PCBs). 3. **Stability:** The vacuum-sealed environment protects the quartz crystal from humidity and atmospheric pressure changes. --- ### 4. Typical Pin Configuration (DIP-14 Style) Most MHO series oscillators in this footprint follow a standard 4-pin layout within a 14-pin grid: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Tri-state Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | Power supply input (+5V) | --- ### 5. Common Applications * **Microprocessors:** Providing the primary heartbeat for CPUs. * **Networking:** Synchronizing data transmission in Ethernet or Serial equipment. * **Industrial Control:** Timing for PLCs (Programmable Logic Controllers). * **Legacy Systems:** Often used in older motherboard designs or DIY electronics kits due to the easy-to-solder DIP package.
