The **MHO+36FCG-R** is a specific part number for a high-performance **Crystal Oscillator**. It is commonly manufactured by companies like MtronPTI and is designed for applications requiring stability and reliability in telecommunications and industrial equipment. ### 1. Technical Specifications | Parameter | Details | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Frequency Range** | Typically 1.0 MHz to 156.25 MHz (Model specific) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | +3.3 VDC or +5.0 VDC (Series dependent) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's construction and performance: * **MHO:** Identifies the product series (Metal package, Thru-hole, High-frequency Oscillator). * **+:** Usually indicates a specific voltage tolerance or enhanced feature set. * **3:** Refers to the Supply Voltage (e.g., 3.3V). * **6:** Represents the Frequency Stability (e.g., ±20ppm, ±50ppm, or ±100ppm depending on the datasheet revision). * **F:** Denotes the Operating Temperature range (often -40°C to +85°C). * **CG:** Refers to the Duty Cycle and Output type (e.g., 45/55% Symmetry). * **-R:** Indicates **RoHS Compliance** (Lead-free). --- ### 3. Key Electronic Characteristics #### Frequency Stability This part is designed to maintain a very precise clock signal. The stability is measured in Parts Per Million (PPM), ensuring that digital circuits remain synchronized even as the temperature changes. #### Package Construction It uses a **Hermetically Sealed Metal Can**. This is critical for: * **EMI Shielding:** Reducing electromagnetic interference. * **Longevity:** Protecting the internal quartz crystal from moisture and atmospheric contaminants. #### Applications Due to its through-hole (DIP) design, it is frequently used in: * Legacy telecommunications hardware. * Industrial control systems. * Test and measurement equipment. * Prototyping on PCBs where surface-mount components are not preferred. --- ### 4.
