The **MHO+73TBD-R** is a specific part number belonging to a series of **Crystal Oscillators**, typically manufactured by companies like **MtronPTI**. These components are critical for providing a stable clock signal in electronic circuits. --- ### 1. Part Number Breakdown While specific prefixes can vary slightly by manufacturer, the code generally follows this logic: | Segment | Description | Typical Specification | | :--- | :--- | :--- | | **MHO** | Series Name | Metal Hybrid Oscillator (14-pin DIP or similar) | | **+** | RoHS Compliance | Indicates Lead-Free/RoHS compliant status | | **7** | Operating Voltage | Often indicates 5.0V or 3.3V (Check datasheet) | | **3** | Stability/Temp | Defines frequency stability (e.g., ±50ppm or ±100ppm) | | **TBD** | Frequency/Custom | Often a placeholder for the specific MHz frequency | | **-R** | Packaging | Tape & Reel or RoHS specific suffix | --- ### 2. Key Technical Specifications Based on the standard **MHO series** architecture, these parts typically feature the following characteristics: * **Package Type:** Through-hole (DIP) 14-pin or 8-pin metal canister package. * **Output Logic:** HCMOS/TTL compatible. * **Frequency Range:** Usually spans from 1.000 MHz to over 150.000 MHz. * **Duty Cycle:** Generally 40/60% or 45/55%. * **Startup Time:** Fast startup (typically <10ms) to ensure the system boots correctly. --- ### 3. Functional Pinout For a standard 14-pin DIP package (where only 4 pins are usually active), the configuration is typically: | 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 | --- ### 4. Typical Applications The MHO+ series is used in "legacy" or industrial hardware where through-hole mounting is preferred over Surface Mount Technology (SMT): 1. **Industrial Controls:** Reliability in high-interference environments. 2. **Embedded Systems:** Providing master clocks for Microcontrollers (MCUs). 3. **Networking Equipment:** Timing for data transmission. 4. **Test & Measurement:** Stable reference signals for lab equipment. ---
