The part number **MHO+72FGG-R** typically refers to a specialized **Crystal Oscillator** or a frequency control component, often manufactured by companies like **MtronPTI**. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Technical Specifications Table | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | Surface Mount Device (SMD) | | **Dimensions** | Often 5.0 x 7.0 mm (standard high-reliability footprint) | | **Output Type** | CMOS / TTL Compatible | | **Voltage Supply** | Usually 3.3V or 5.0V (Variant dependent) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±20ppm to ±100ppm | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Part Number Breakdown To understand the electronic capabilities, we can decode the nomenclature: * **MHO:** This series prefix usually denotes a high-reliability, metal-can, or ceramic-packaged crystal oscillator designed for through-hole or SMD mounting. * **72:** Often indicates the package size or a specific voltage/output configuration (e.g., 5.0V or 3.3V operation). * **FGG:** This is a code for **Frequency Stability** and **Operating Temperature Range**. In many timing component catalogs, "G" mappings refer to specific parts per million (ppm) tolerances. * **-R:** Stands for **RoHS Compliant**, meaning the part is manufactured without lead (Pb) and other restricted hazardous substances. --- ## 3. Key Electronic Features ### A. Frequency Generation The core of this device is a quartz crystal blank that vibrates at a specific frequency when a voltage is applied (the Piezoelectric effect). The internal circuitry includes: * A sustaining amplifier. * An output buffer to drive external loads. ### B. Output Characteristics The **MHO+** series is known for providing a clean square wave signal. It is used as the "heartbeat" for microprocessors, FPGAs, and communication ICs. It features low "jitter" (timing uncertainty), which is critical for high-speed data transmission. ### C. Environmental Durability Because these are often used in industrial or military-lite applications, they are hermetically sealed. This prevents moisture and atmospheric contaminants from affecting the quartz crystal's vibration frequency over time (Aging). --- ## 4. Typical Applications * **Networking:** Routers, switches, and fiber-optic modules. * **Embedded Systems:** Providing clock signals to ARM or AVR microcontrollers. * **Industrial Control:** PLCs (Programmable Logic Controllers) where temperature stability is required. * **Test & Measurement:** Oscilloscopes and signal generators.
