The **MHO+41TFD-R** is a specific part number belonging to a series of high-precision **Crystal Oscillators** (XO), typically manufactured by companies like MtronPTI. These components are used to generate stable clock signals for digital circuits. --- ### 1. Technical Specifications The "MHO" series generally refers to a 14-pin or 8-pin DIP (Dual In-line Package) compatible oscillator. Below are the typical technical parameters for this part: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Fixed Output Crystal Oscillator | | **Frequency Range** | Usually custom-defined (specified in MHz) | | **Output Type** | TTL / CMOS Compatible | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard for this series) | | **Package Style** | 4-Pin / 14-Pin DIP Metal Can | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±100ppm to ±25ppm (depending on suffix) | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually follows this logic: * **MHO:** Identifies the product series (Metal Can, HCMOS/TTL). * **+:** Often indicates RoHS compliance (Lead-Free). * **41:** Refers to the specific stability and voltage configuration (e.g., 5V, +/- 50ppm). * **T:** Temperature range indicator (T usually signifies Industrial: -40°C to +85°C). * **F:** Frequency stability or symmetry code. * **D:** Duty cycle specification (often 40/60% or 45/55%). * **R:** Tape and Reel or specific Revision code. --- ### 3. Pin Configuration In the standard 14-pin DIP footprint (where only 4 pins are actually present), the layout is typically: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Case Ground | | **Pin 8** | Output | The generated square wave frequency | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Common Applications Due to its rugged metal casing and through-hole design, the MHO+41TFD-R is commonly found in: * **Legacy Computing:** Motherboards and industrial controllers. * **Communication Equipment:** Base stations and networking hardware. * **Test & Measurement:** Oscilloscopes and signal generators. * **Embedded Systems:** Providing a master clock for Microprocessors. ---
