The part number **MHO+47FCG-R** refers to a high-precision, industrial-grade **Quartz Crystal Oscillator** typically manufactured by companies like **MtronPTI**. Below is a breakdown of the electronic specifications, nomenclature, and functional characteristics of this component. --- ### 1. Technical Specifications The part belongs to the **MHO series**, which are metal-can, through-hole oscillators known for their reliability in harsh environments. | Feature | Specification | | :--- | :--- | | **Component Type** | Clock Oscillator (Fixed Frequency) | | **Package Type** | 14-pin DIP (Full Size) - 4 pins connected | | **Frequency Range** | Typically fixed (refer to label for specific MHz) | | **Output Type** | CMOS / TTL Compatible | | **Operating Voltage** | +5.0 VDC (Standard for MHO series) | | **Frequency Stability** | ±100ppm to ±25ppm (depending on sub-grade) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the **-R** suffix) | --- ### 2. Part Number Deciphering To understand the specific electronic behavior, we can break down the alphanumeric code: | Segment | Meaning | Description | | :--- | :--- | :--- | | **MHO** | Series Name | Metal Hole Oscillator (14-pin DIP footprint). | | **+** | Voltage Symbol | Indicates positive voltage operation (5V). | | **4** | Stability Code | Often represents ±50ppm or ±25ppm stability. | | **7** | Duty Cycle | Represents a 40/60% or 45/55% tight duty cycle. | | **F** | Temperature Range | "F" usually denotes Industrial range (-40°C to +85°C). | | **CG** | Configuration | Internal design code for output load (e.g., 15pF or 50pF). | | **-R** | Compliance | RoHS Lead-Free compliant. | --- ### 3. Pin Configuration Since this is a standard 14-pin DIP package, only four pins are active. The electronic footprint is as follows: ```text Top View +-----------+ 1 | [ ] [ ] | 14 (Vcc / Power) | | 7 | [ ] [ ] | 8 (Output Signal) +-----------+ ``` * **Pin 1:** N/C (No Connection) or Tri-state Enable/Disable. * **Pin 7:** Case Ground (Vss). * **Pin 8:** Output (Square wave signal). * **Pin 14:** Supply Voltage (+5V). --- ### 4. Key Electronic Applications This component is used to provide a stable clock pulse for digital circuits. * **Microprocessor Clocks:** Providing the "heartbeat" for CPUs and MCUs. * **Embedded Systems:** Used in industrial controllers where temperature fluctuations are common. * **Legacy Hardware:** Maintenance and repair of older networking equipment that requires 5V logic.
