The **MHO+31FAG-R** is a specific part number typically associated with **MHO (Metal Hybrid Oxide)** series components, often manufactured by companies like *Tusonix* (now part of CTS Corporation) or specialized oscillator manufacturers. Based on the alphanumeric coding, this part is an **HCMOS/TTL Clock Oscillator**. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Technical Specifications | Parameter | Specification | |:--- |:--- | | **Component Type** | Crystal Oscillator (Clock) | | **Package Style** | 14-Pin DIP (Thru-Hole) - often 4 pins connected | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Typically 5.0V DC | | **Frequency Stability** | ±100ppm (Standard for '31' series) | | **Operating Temp Range** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (Indicated by the '-R' suffix) | --- ### 2. Functional Characteristics #### A. Internal Construction The device consists of a quartz crystal resonator combined with an integrated circuit (IC) that handles the oscillation and output buffering. This ensures a stable square wave signal used for timing in digital circuits. #### B. Pin Configuration (Standard 14-Pin DIP Layout) Even though it has a 14-pin footprint, usually only 4 pins are active: * **Pin 1:** NC (No Connection) or Tri-state Control. * **Pin 7:** Ground (GND). * **Pin 8:** Output Signal. * **Pin 14:** Supply Voltage (Vcc). #### C. The "-R" Suffix The suffix indicates **RoHS Compliance**. This means the part is manufactured without lead (Pb) and other hazardous substances, making it suitable for modern environmentally regulated production. --- ### 3. Common Applications This component is used as a "heartbeat" for various electronic systems to synchronize data processing: * **Microprocessors:** Providing the base clock frequency. * **Embedded Systems:** Timing for microcontrollers (MCUs). * **Communication Equipment:** Synchronizing data transmission in networking hardware. * **Legacy Hardware:** Maintenance and repair of older industrial motherboards. --- ### 4.
