The **MHO364FAD-R** is a specific electronic component, typically categorized as a **High-Frequency SAW (Surface Acoustic Wave) Filter** or a high-stability **Crystal Oscillator** (depending on the specific manufacturer series, though most commonly associated with radio frequency signal processing). Below is a breakdown of its technical aspects and electronic characteristics. --- ### 1. Technical Specifications The following table outlines the general technical parameters typical for this component series: | Parameter | Typical Value / Range | | :--- | :--- | | **Component Type** | SAW Filter / Oscillator | | **Center Frequency** | Varies by sub-model (Commonly in MHz range) | | **Package Type** | SMD (Surface Mount Device) | | **Operating Temperature** | -40°C to +85°C | | **Impedance** | Typically 50 $\Omega$ | | **RoHS Status** | Compliant (indicated by -R suffix) | ### 2. Key Electronic Parts & Construction The internal architecture of an MHO (Metal-Hybrid-Oscillator/Filter) series component consists of several critical layers: * **Piezoelectric Substrate:** Usually made of Lithium Tantalate ($LiTaO_3$) or Lithium Niobate ($LiNbO_3$). This material converts electrical signals into mechanical (acoustic) waves and back again. * **Interdigital Transducers (IDTs):** Microscopic interleaved metal "fingers" deposited on the substrate. They determine the frequency response of the part through their spacing and width. * **Hermetic Seal:** The "Metal" part of the MHO prefix refers to the robust metallic casing that protects the sensitive internal crystal/substrate from electromagnetic interference (EMI) and atmospheric moisture. * **Gold/Tin Plating:** The pads on the underside are usually gold-plated to ensure low contact resistance and prevent oxidation during the PCB reflow soldering process. ### 3. Functional Role in a Circuit In a telecommunications or RF circuit, the MHO364FAD-R serves the following purposes: 1. **Frequency Selection:** It allows specific signal frequencies to pass while attenuating (blocking) unwanted noise and interference. 2. **Clock Generation:** If utilized as an oscillator, it provides the "heartbeat" for microprocessors or RF synthesizers. 3. **Phase Stability:** Known for high Q-factors, meaning it maintains a very sharp and stable frequency even under thermal stress. --- ### 4. Part Number Breakdown The suffix and prefix provide specific information about the manufacturing standards: * **MHO:** Series designation (often Metal Hermetic Oscillator/Filter). * **364:** Specific design/frequency footprint code. * **FAD:** Internal specification code (Tolerance, Load Capacitance, or Temperature Stability). * **-R:** Indicates **RoHS Compliance** (Lead-free) and often implies **Tape & Reel** packaging for automated assembly.
