The **MHO+37TAAG-R** is a high-precision, industrial-grade **Quartz Crystal Oscillator** manufactured by **MtronPTI**. It is designed for timing and frequency control applications where stability and reliability are critical. --- ### ## Technical Specifications Below are the primary electronic characteristics of the MHO+37TAAG-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-Pin DIP (Through-Hole) | | **Output Type** | CMOS / TTL Compatible | | **Frequency Range** | Typically fixed (Customizable per order) | | **Operating Voltage** | 5.0 VDC (Standard for MHO series) | | **Stability** | ±100 ppm (Standard variation) | | **Operating Temperature** | 0°C to +70°C (Commercial) / -40°C to +85°C (Industrial) | | **RoHS Status** | Compliant (Indicated by "-R" suffix) | --- ### ## Key Features 1. **Package Design**: The "MHO" designation refers to a full-size (14-pin) metal DIP package. This metal casing provides excellent **Electromagnetic Interference (EMI) shielding**, making it suitable for noisy electrical environments. 2. **Output Logic**: It utilizes CMOS/TTL logic, allowing it to interface directly with microprocessors, FPGAs, and digital clock circuits without additional level-shifting components. 3. **Hermetic Sealing**: The part is hermetically sealed to prevent moisture and atmospheric contaminants from affecting the quartz crystal, ensuring long-term frequency aging stability. 4. **RoHS Compliance**: The **-R** suffix confirms the part is lead-free and compliant with environmental regulations. --- ### ## Pin Configuration (Standard 14-Pin DIP) While the physical component has 14 pins, only 4 are typically active: * **Pin 1**: N/C (No Connection) or Tri-state Enable/Disable. * **Pin 7**: Case Ground (GND). * **Pin 8**: Output Signal. * **Pin 14**: Supply Voltage (Vcc). --- ### ## Typical Applications * **Networking**: Used in routers, switches, and modems for packet timing. * **Industrial Control**: Timing for PLCs and embedded industrial computers. * **Legacy Systems**: Often used as a replacement part in older hardware that requires through-hole components rather than modern Surface Mount Devices (SMD).
