The **MHO361TCD-R** is a specific surface-mount electronic component, typically identified as a **high-precision, temperature-compensated crystal oscillator (TCXO)** or a specialized clock oscillator. These components are critical in telecommunications and high-stability electronic systems. --- ### 1. Key Technical Specifications Below are the typical specifications for the MHO361 series (please note that specific suffixes like "TCD" indicate temperature range and output logic): | Feature | Specification Details | | :--- | :--- | | **Component Type** | Temperature Compensated Crystal Oscillator (TCXO) | | **Package Type** | SMD (Surface Mount Device) | | **Standard Frequency** | Varies (Commonly 10MHz, 12.8MHz, or 20MHz) | | **Operating Voltage** | Typically 3.3V or 5.0V DC | | **Output Type** | CMOS or Clipped Sine Wave | | **Frequency Stability** | ±0.5ppm to ±2.5ppm (depending on temp range) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Breakdown of the Part Number Components While manufacturers have unique coding, "MHO3" series parts generally follow this logic: * **MHO:** Manufacturer series prefix (often associated with MtronPTI or similar high-precision timing manufacturers). * **361:** Refers to the physical package size (e.g., 5.0 x 3.2 mm or 7.0 x 5.0 mm). * **TCD:** * **T:** Temperature Compensated. * **C:** CMOS Output compatibility. * **D:** Specific voltage requirement (often 3.3V). * **-R:** Indicates **RoHS Compliant** (Lead-free). --- ### 3. Functional Internal Parts The MHO361TCD-R is not a single transistor but an integrated module consisting of several sub-parts: 1. **Quartz Crystal Resonator:** The heart of the component that provides the mechanical vibration at a specific frequency. 2. **Compensation Network:** A thermistor-based circuit that senses ambient temperature and adjusts the load capacitance to keep the frequency stable. 3. **Oscillator IC:** An integrated circuit that sustains the oscillation and provides the output buffer. 4. **Voltage Regulator:** Internal circuitry to ensure the frequency does not drift if the input voltage fluctuates slightly. --- ### 4. Common Applications Due to its high stability, this part is used in: * **GPS Receivers:** Where precise timing is required to calculate location. * **Basestations:** For synchronizing cellular data signals. * **Wi-Fi/Bluetooth Modules:** To maintain a steady carrier wave. * **Embedded Systems:** Industrial controllers that operate in fluctuating temperature environments.
