The **MHO+35TFG-R** is a specific type of **Crystal Oscillator** (often categorized under Frequency Control products). These components are essential in electronics for providing a stable clock signal to microprocessors and digital circuits. --- ### 1. Component Overview The "MHO" series typically refers to a family of **Half-Size (8-pin style) DIP Metal Package** oscillators. The suffix "TFG-R" provides specific details regarding its electrical characteristics and compliance. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Package Style** | 8-Pin DIP (Half-Size) through-hole | | **Frequency Stability** | Generally ±50ppm to ±100ppm (Standard) | | **Output Type** | HCMOS / TTL Compatible | | **RoHS Status** | "R" suffix indicates RoHS Compliant | --- ### 2. Breakdown of Part Number Coding While manufacturers vary slightly, the standard nomenclature for this series breaks down as follows: * **MHO:** Series designation (Metal Half-size Oscillator). * **+:** Often indicates a specific voltage or lead-free process enhancement. * **3:** Usually represents the operating voltage (3.3V is common for '3', though some brands use it for 5V; check the datasheet). * **5:** Often denotes the frequency stability (e.g., 5 = ±50ppm). * **T:** Denotes "Tristate" functionality (allows the output to be disconnected/high-impedance). * **F:** Frequency range or temperature range indicator (Industrial -40°C to +85°C is common). * **G:** Tight symmetry or specific load capacitance. * **-R:** RoHS (Restriction of Hazardous Substances) Compliant. --- ### 3. Pin Configuration (Standard 8-pin DIP Half-Size) Even though it is an 8-pin package, only 4 pins are typically functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Enable/Disable (Tristate) | | **4** | GND | Case Ground | | **5** | Output | The generated clock signal (Square Wave) | | **8** | Vcc | Positive Power Supply (e.g., +3.3V or +5V) | --- ### 4. Key Application Use Cases * **Microcontrollers:** Providing the master clock for CPUs. * **Networking:** Timing for Ethernet or data transmission hardware. * **Industrial:** Used in PLCs and control boards due to the rugged metal casing. * **Legacy Systems:** Ideal for replacing older through-hole timing components. ---
