The **MHO+35TAG-R** belongs to a specific category of electronic components known as **Crystal Oscillators**. These parts are essential for providing a stable clock signal in digital circuits, telecommunications, and computing hardware. Below is a detailed breakdown of its specifications, construction, and functionality. --- ### 1. Technical Specifications The part number typically follows a standardized coding system used by manufacturers like **MtronPTI**. | Feature | Description | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Usually "Full Size" | | **Frequency Range** | Typically 1.0 MHz to 150.0 MHz (Specific to exact sub-model) | | **Operating Voltage** | 5.0V (Standard for the MHO series) | | **Output Logic** | HCMOS / TTL Compatible | | **Stability** | Usually ±100ppm, ±50ppm, or ±25ppm (depending on the "3" code) | | **RoHS Status** | The **-R** suffix indicates RoHS Compliance (Lead-free) | --- ### 2. Part Number Breakdown Understanding the alphanumeric code helps identify the specific capabilities of the component: * **MHO**: The Series identifier (High-speed CMOS/TTL 5V Oscillator). * **+**: Often indicates a specific revision or lead-free process enhancement. * **3**: Represents the Frequency Stability (e.g., 3 often denotes ±50ppm or ±100ppm over temperature). * **5**: Usually indicates the supply voltage (5V). * **T**: Indicates the Operating Temperature Range (Standard is 0°C to +70°C). * **AG**: Package/Pin configuration code (Thru-hole 14-pin DIP style). * **-R**: RoHS Compliant. --- ### 3. Internal Components & Operation The MHO+35TAG-R is an **Active Oscillator**, meaning it contains more than just a piece of quartz. It is an integrated circuit that includes: 1. **Quartz Crystal Blank**: The physical resonator that vibrates at a specific frequency. 2. **Oscillator IC**: A circuit that sustains the vibration of the crystal and converts it into a square wave. 3. **Bypass Capacitors**: Internal filtering to reduce electronic noise. 4. **Buffer/Driver**: Ensures the output signal is strong enough to drive multiple digital gates (fan-out). --- ### 4. Common Applications These oscillators are "Legacy" style components, meaning they are frequently found in older hardware or industrial equipment that requires through-hole mounting rather than modern surface-mount (SMD) technology. * **Microprocessor Clocks**: Providing the "heartbeat" for CPUs. * **Networking Gear**: Timing for routers and switches. * **Industrial Controllers**: PLCs and automation hardware. * **Embedded Systems**: Legacy 8-bit or 16-bit development boards. ---
