The **MHO+13TBD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like MtronPTI. These components are used to generate precise clock signals for digital circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) | | **Output Type** | TTL / HCMOS Compatible | | **Supply Voltage** | 5.0V DC (Standard for MHO series) | | **Frequency Range** | Usually custom-specified (e.g., 1.0 MHz to 100 MHz) | | **Stability** | ±100ppm, ±50ppm, or ±25ppm (depending on suffix) | | **Operating Temperature** | 0°C to +70°C (Standard Commercial) | --- ### 2. Breakdown of the Part Number While specific manufacturers vary slightly, the coding usually breaks down as follows: * **MHO:** Series designation (Metal thru-hole oscillator). * **+:** Often indicates RoHS compliance (Lead-free). * **13:** Typically refers to the **Frequency Stability** (e.g., ±50ppm) and the **Duty Cycle** (e.g., 40/60%). * **T:** Represents the Output Type (TTL/HCMOS). * **BD:** Represents the specific Package Code (Full-size 14-pin DIP footprint, though only 4 pins are usually present). * **-R:** Indicates **RoHS Compliant**. --- ### 3. Pin Configuration For a standard 14-pin DIP footprint (MHO series), the electrical connections are usually: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC / Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated square wave frequency | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Key Applications * **Microprocessor Clocks:** Providing the "heartbeat" for CPUs and Microcontrollers. * **Networking:** Timing for Ethernet controllers and routers. * **Industrial Control:** Timing for PLC (Programmable Logic Controllers). * **Legacy Hardware:** Common in older computer hardware and radio equipment due to the through-hole (DIP) design.
