The **MHO+42FAAD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, manufactured by companies like MtronPTI. These components are essential in electronic circuits for generating stable clock signals. --- ### 1. Component Breakdown The part number follows a specific nomenclature that defines its physical and electrical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | Crystal Oscillator | Provides a fixed-frequency pulse (clock signal). | | **Package** | 14-pin DIP (DIL) | A "Full Size" through-hole package (only 4 pins are usually active). | | **Output Type** | HCMOS/TTL | Compatible with standard digital logic levels. | | **Voltage** | 5.0V (Standard) | Common operating voltage for "MHO" series. | | **RoHS Status** | Compliant (-R) | The suffix "-R" indicates lead-free/RoHS compliance. | --- ### 2. Technical Specifications While exact specifications can vary by the custom frequency ordered, the **MHO+ series** generally adheres to these parameters: * **Frequency Range:** Typically available from 1.000 MHz up to 100.000 MHz. * **Stability:** Often ±100ppm, ±50ppm, or ±25ppm depending on the specific sub-rating. * **Operating Temperature:** Generally 0°C to +70°C (Standard) or -40°C to +85°C (Industrial). * **Pin Configuration:** * **Pin 1:** NC (No Connection) or Tri-state Enable/Disable. * **Pin 7:** Case Ground (GND). * **Pin 8:** Output. * **Pin 14:** Supply Voltage (Vcc). --- ### 3. Applications These oscillators are used in legacy and industrial hardware where high stability and through-hole mounting are required: 1. **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. 2. **Embedded Systems:** Industrial controllers and automation timing. 3. **Data Communications:** Synchronizing data transmission in networking equipment. 4. **Legacy Repairs:** Replacing aging oscillators in older computer hardware or test equipment. --- ### 4. Key Advantages * **Hermetically Sealed:** The metal "can" protects the quartz crystal from humidity and environmental interference. * **Easy Prototyping:** The 14-pin DIP footprint is easy to use on breadboards and through-hole PCBs. * **Reliability:** Metal packages offer better EMI (Electromagnetic Interference) shielding compared to some plastic SMD alternatives. ---
