The **MHO+13TCG-R** is a specific series of **Crystal Oscillators** typically manufactured by companies like Jauch Quartz or similar electronic component specialists. This component is a high-precision frequency generator used in timing circuits. --- ## 1. Technical Specifications The MHO+ series belongs to the **HC-49/U or DIL-14 package family**, often utilized for their stability and legacy compatibility. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (SPXO) | | **Package Style** | DIL-14 (Full size) or DIL-8 (Half size) Metal Can | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{dd}$)** | Usually +5.0V DC (Standard for MHO series) | | **Frequency Stability** | ±25ppm to ±100ppm (Depending on specific grade) | | **Operating Temperature** | -10°C to +70°C (Standard commercial) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ## 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually follows this logic: * **MHO+**: The series prefix, indicating a metal-can, hermetically sealed through-hole oscillator. * **13**: Often refers to the supply voltage or specific stability grade (1 = 5V, 3 = Stability code). * **T**: Tri-state function (Pin 1 can be used to enable/disable the output). * **C**: CMOS/TTL output compatibility. * **G**: Operating temperature range code. * **R**: RoHS (Lead-free) compliant. --- ## 3. Pin Configuration (DIL-14 Full Size) The device usually operates with 4 active pins despite the large casing: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connection | | **7** | GND | Ground / Case Connection | | **8** | Output | The generated clock signal (Square Wave) | | **14** | $V_{cc}$ | Power Supply (+5V) | --- ## 4. Key Electronic Characteristics * **Hermetic Sealing:** The metal "can" is resistance-welded to protect the quartz crystal from humidity and atmospheric contaminants, ensuring long-term frequency aging stability. * **Integrated IC:** Unlike a simple 2-pin crystal, the MHO+ includes the oscillating circuit and a buffer amplifier inside the package. It only requires a DC power source to function. * **Load Capacitance:** Generally designed to drive a 15pF to 50pF load. ---
