The **MHO+23FAD-R** is a specific part number typically associated with a **Crystal Oscillator**. These components are fundamental in electronics for generating a stable clock signal or frequency reference. Below is a detailed breakdown of the technical aspects and characteristics of this part. --- ### 1. General Specifications The part number follows a specific nomenclature used by manufacturers (often **MtronPTI** or similar timing component providers). | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | HCMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Mounting Type** | Through-Hole | | **Voltage Supply** | Typically 5.0V or 3.3V (Model dependent) | ### 2. Part Number Breakdown (Typical) While internal coding can vary slightly by manufacturer, here is how "MHO+23FAD-R" is generally deciphered: * **MHO:** Series identifier (Metal Hollow/Oversized package, often 14-pin DIP compatible). * **+:** Usually indicates Lead-Free / RoHS compliance. * **23:** Represents the stability and operating temperature range (e.g., ±50ppm or ±100ppm). * **F:** Frequency stability code or specific output symmetry (e.g., 45/55%). * **A:** Voltage code (Often "A" represents 5.0V). * **D:** Tri-state Enable/Disable function (Pin 1). * **-R:** RoHS compliant. ### 3. Key Electronic Characteristics Crystal oscillators like the MHO+ series provide several critical functions: 1. **Frequency Stability:** Unlike a standard RC circuit, crystal oscillators provide precision measured in parts per million (PPM), ensuring that microprocessors or communication interfaces stay synchronized. 2. **Tri-State Functionality:** The "D" in the suffix usually indicates that the oscillator has an enable/disable pin. This allows the output to be set to a high-impedance state, saving power or allowing bus sharing. 3. **Metal Can Shielding:** The package is typically a hermetically sealed metal case. This acts as a Faraday cage, reducing Electromagnetic Interference (EMI) and protecting the quartz crystal from environmental moisture. --- ### 4. Common Applications * **Legacy Computing:** Motherboards and peripheral cards using through-hole technology. * **Industrial Control:** PLCs and timing modules where SMD (Surface Mount) is not desired for vibration resistance. * **Communication Equipment:** Providing the base baud rate for serial communication (RS-232/485). * **Test & Measurement:** Internal clock references for oscilloscopes or signal generators. ---
