The **MHO363TAG-R** is a high-performance, crystal-based oscillator, typically categorized under frequency control components. It is manufactured by **MtronPTI**, a company specializing in high-reliability timing and filter solutions. --- ## Technical Specifications The MHO series generally refers to **Metal Half-size Oven-controlled** or high-stability clock oscillators. Below are the typical technical parameters associated with this specific part class: | Feature | Specification | | :--- | :--- | | **Package Type** | 14-pin DIP (Half-size metal can) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | 3.3V or 5.0V (Standard) | | **Stability** | $\pm$25ppm to $\pm$100ppm (Variable by sub-code) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Frequency Range** | 1.000 MHz to 100.000 MHz | --- ## Key Features & Construction 1. **Hermetic Sealing:** The "MHO" series utilizes a metal package that is resistance-welded to ensure a vacuum or inert gas environment. This protects the quartz crystal from aging caused by moisture or atmospheric contaminants. 2. **Tri-state Functionality:** The "T" in the suffix often denotes **Tri-state (Enable/Disable)** capability. This allows the output to be placed in a high-impedance state, which is useful for testing or power saving. 3. **Through-Hole Mounting:** Unlike modern SMD (Surface Mount Device) components, the MHO363 uses pins for through-hole PCB mounting, providing superior mechanical stability in high-vibration environments. 4. **RoHS Compliance:** The "-R" suffix explicitly indicates that the part is **RoHS Compliant**, meaning it is manufactured without lead or other restricted hazardous substances. --- ## Common Applications Because of its robust metal casing and reliability, the MHO363TAG-R is commonly found in: * **Telecommunications:** Base stations and switching equipment. * **Industrial Control:** PLCs and ruggedized automation hardware. * **Legacy Systems:** Replacement parts for older medical or test equipment that utilize DIP-style footprints. * **Aerospace & Defense:** Low-tier instrumentation where high-reliability timing is required without the cost of a full TCXO/OCXO. --- ## Pin Configuration (Typical) * **Pin 1:** NC (No Connection) or Tri-state Control. * **Pin 7:** Case Ground (GND). * **Pin 8:** Output Signal. * **Pin 14:** Supply Voltage ($V_{cc}$).
