The part number **MHO+52FAAD-R** refers to a high-precision **Crystal Oscillator** manufactured by MtronPTI. These components are essential in electronics for providing a stable clock signal to microprocessors and communication interfaces. --- ### 1. Technical Specifications The code follows a specific nomenclature used by MtronPTI. Below is the breakdown of its core technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | 5.0 VDC (Typical) | | **Package Style** | 14-pin DIP (DIP-14) Metal Can | | **Frequency Stability** | ±50 ppm or ±100 ppm (Depending on full suffix) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Part Number Breakdown To understand the specific capabilities, we can deconstruct the identifier: 1. **MHO**: Represents the product series (HCMOS/TTL compatible, 5.0V, 14-pin DIP package). 2. **+**: Indicates a specific lead-free/RoHS compliant process. 3. **52**: Usually designates the frequency stability (e.g., 50 ppm). 4. **F**: Operating temperature range code (typically Industrial -40°C to +85°C). 5. **AA**: Symmetry/Duty Cycle and Tri-state function options. 6. **D**: The frequency code (Note: The specific frequency in MHz is usually printed on the physical device). 7. **-R**: RoHS Compliant. --- ### 3. Key Applications Because of its rugged "Metal Can" DIP-14 package, this part is often found in: * **Legacy Computing:** Industrial PCs and motherboards requiring 5V logic. * **Telecommunications:** Timing for network switches and routers. * **Instrumentation:** Test and measurement equipment where electromagnetic interference (EMI) shielding is necessary (the metal case is grounded). * **Embedded Systems:** Providing clock pulses for microcontrollers. --- ### 4. Physical Characteristics * **Form Factor:** Through-hole mounting (THM). * **Shielding:** The hermetically sealed metal package provides excellent protection against environmental moisture and reduces RF emissions. * **Pinout:** Only 4 pins are typically active in the 14-pin footprint (Pin 1: NC or Tristate, Pin 7: Ground, Pin 8: Output, Pin 14: Vcc).
