The **MHO+46TFD-R** is a specific part number belonging to the **MHO Series** of high-stability quartz crystal oscillators, typically manufactured by companies like **MtronPTI**. These components are designed for precision timing and frequency control in demanding industrial or communication environments. --- ### 1. Technical Specifications Table Below is a breakdown of the typical characteristics associated with this specific model series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) | | **Frequency Range** | Typically 1.0 MHz to 150.0 MHz (Specific to exact sub-coding) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | +5.0V DC (Standard for MHO series) | | **Stability** | ±100ppm to ±25ppm (Depending on grade) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ### 2. Breakdown of the Part Number While manufacturers have slight variations, the alphanumeric string generally decodes as follows: * **MHO:** Identifies the product series (Metal-can, High-stability Oscillator). * **4:** Represents the voltage and stability combination (often indicating 5.0V operation). * **6:** Often refers to the Duty Cycle requirement (e.g., 40/60% or 45/55%). * **TFD:** These characters usually designate the Operating Temperature range and the Tri-state (Enable/Disable) functionality. * **R:** Indicates **RoHS Compliance** (Lead-free). --- ### 3. Key Electronic Features * **Hermetic Sealing:** The part is housed in a metal "can" package, which is resistance-welded to protect the internal quartz crystal from moisture and atmospheric contaminants. * **Tri-state Functionality:** This allows the output to be placed in a high-impedance state, which is useful for testing or for power saving when the clock signal is not required. * **Low Phase Jitter:** Designed for data communication applications where timing precision is critical to minimize bit error rates. --- ### 4. Common Applications 1. **Networking Equipment:** Routers, switches, and gateways. 2. **Industrial Controllers:** PLC (Programmable Logic Controllers) and automation hardware. 3. **Legacy Computing:** Motherboards or expansion cards requiring a standard DIP footprint. 4. **Test & Measurement:** Oscilloscopes and signal generators.
