The **MHO+38TAD-R** is a specific series of **Crystal Oscillators** (specifically categorized under the MHO series) manufactured by MtronPTI. These components are critical for providing a stable clock signal in digital circuits. --- ### 1. Technical Specifications Below is a breakdown of the typical technical characteristics found in this specific series: | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Typically 5.0V DC (Standard for MHO series) | | **Frequency Range** | Usually between 1.0 MHz to 100.0 MHz | | **Operating Temperature** | Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) | --- ### 2. Part Number Breakdown To understand the "MHO+38TAD-R" naming convention, we look at the standard MtronPTI coding logic: * **MHO:** Identifies the product series (Metal Half-size or Full-size DIP Package). * **+:** Often indicates RoHS compliance (Lead-free). * **38:** Usually refers to the specific frequency stability or a variation in the voltage/output (e.g., ±50ppm or ±100ppm). * **TAD:** * **T:** Temperature Range (often indicates a specific thermal operating window). * **A:** Tightness/Symmetry of the waveform. * **D:** Duty Cycle specification (usually 40/60% or 45/55%). * **-R:** Indicates **RoHS Compliant** (Restriction of Hazardous Substances). --- ### 3. Key Electronic Components Inside An oscillator like the MHO+38TAD-R is not a simple crystal; it is an active circuit consisting of: 1. **Quartz Crystal Slice:** The mechanical resonator that vibrates at a specific frequency. 2. **Oscillator IC:** An internal integrated circuit that provides the amplification and feedback necessary to sustain oscillation. 3. **Bypass Capacitors:** Internal surface-mount capacitors to filter noise from the power supply. 4. **Buffer/Driver:** An output stage that ensures the signal can drive other logic gates (TTL/CMOS) without degrading. --- ### 4. Application Areas These parts are commonly found in legacy and industrial hardware due to their robust through-hole design: * **Embedded Systems:** Providing a heartbeat for microprocessors. * **Telecommunications:** Timing for data transmission hardware. * **Industrial Control:** Used in PLCs (Programmable Logic Controllers) where surface-mount components might not be preferred. ---
