The **MHO+43FDD-R** is a specific part number typically associated with **MHO+ Series Clock Oscillators** manufactured by **MtronPTI**. These components are critical in electronic circuits for providing a stable timing signal (clock pulse). --- ### 1. Technical Specifications Table Based on the standard nomenclature for the MtronPTI MHO+ series, here is the breakdown of its technical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Fixed frequency clock source. | | **Package Style** | 14-pin DIP (Full Size) | Metal can, through-hole mounting. | | **Output Type** | HCMOS / TTL | Compatible with high-speed CMOS and TTL logic. | | **Supply Voltage** | 5.0V DC | Standard operating voltage for the MHO+ series. | | **Frequency Stability** | ±100 ppm (Standard) | Stability over temperature (varies by sub-code). | | **Operating Temp** | -40°C to +85°C | Industrial temperature range (indicated by the "R" suffix). | | **RoHS Status** | Compliant | Lead-free construction. | --- ### 2. Key Internal Electronic Parts The device is a "Hybrid" component, meaning it contains several integrated parts inside its hermetically sealed metal case: * **AT-Cut Quartz Crystal:** The heart of the device. It vibrates at a specific mechanical frequency when an electric field is applied. * **Oscillator IC:** An integrated circuit that provides the necessary gain to maintain the crystal's oscillation and converts the sine wave into a square wave (HCMOS/TTL). * **Bypass Capacitor:** Internal capacitance to filter power supply noise and ensure stable operation. * **Metal Header/Cover:** Provides electromagnetic interference (EMI) shielding to prevent the oscillator from affecting nearby components and vice versa. --- ### 3. Pin Configuration (14-pin DIP) Though it has a 14-pin footprint, usually only four pins are electrically connected: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | No connection or Output Enable/Disable. | | **7** | Ground | Circuit and Case Ground. | | **8** | Output | The generated clock signal. | | **14** | Vcc | +5.0V Power Supply. | --- ### 4. Typical Applications * **Microprocessors:** Providing the "heartbeat" for CPUs and Microcontrollers. * **Networking:** Timing for Ethernet controllers and routers. * **Industrial Control:** Reliable timing in harsh environments due to the "R" temperature rating. * **Legacy Systems:** Used often in repairs or designs requiring through-hole components rather than modern surface-mount (SMD) parts.
