The **MHO361FAD-R** is an electronic component primarily classified as a **Crystal Oscillator**. Specifically, it is a high-precision frequency control device used to generate a stable clock signal for digital circuits. --- ## 1. Technical Specifications Below is a breakdown of the typical electronic characteristics for the MHO series (specifically the 361FAD variant): | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package / Case** | 14-pin DIP (Dual In-line Package) - Full Size | | **Supply Voltage (Vcc)** | +5.0V DC (Standard) | | **Output Logic** | HCMOS / TTL Compatible | | **Frequency Stability** | ±25ppm to ±100ppm (depending on grade) | | **Operating Temperature** | -10°C to +70°C (Standard Industrial) | | **Mounting Type** | Through-Hole | --- ## 2. Key Internal Components The "parts" inside this sealed metal can include: 1. **Quartz Crystal Blank:** A precision-cut piece of quartz that vibrates at a specific resonant frequency when an electric field is applied (Piezoelectric effect). 2. **Oscillator IC:** A small silicon chip containing the inverter circuitry, feedback resistors, and output buffers necessary to sustain oscillation. 3. **Bypass Capacitor:** Internal decoupling to reduce power supply noise and stabilize the output signal. 4. **Hermetic Metal Header:** The metal casing (often Kovar or cold-rolled steel) that protects the internal sensitive components from humidity and electromagnetic interference (EMI). --- ## 3. Pin Configuration The MHO361FAD-R typically follows the standard 14-pin DIP footprint, though only 4 pins are usually active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Positive Power Supply (+5V) | --- ## 4. Application and Usage The **"R"** suffix in the part number usually denotes **RoHS Compliance** (Restriction of Hazardous Substances), meaning it is manufactured without lead or other restricted materials. * **Primary Use:** Acting as the "heartbeat" for microprocessors, microcontrollers, and digital signal processors (DSPs). * **Common Industries:** Industrial automation, legacy computing systems, and telecommunications equipment. ---
