The **MHO+41TFG-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is part of the MHO+ series, known for its stability and reliability in industrial and communication applications. --- ### 1. General Specifications The following table summarizes the primary technical parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (Fixed Frequency) | | **Package Type** | 4-Pin Half-Size (DIP) or Through-hole | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{dd}$)** | 5.0V DC (Typical) | | **Frequency Stability** | ±100 ppm (Standard for this series) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the -R suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric code follows MtronPTI’s specific naming convention: * **MHO+**: Series designation (HCMOS/TTL compatible oscillators). * **4**: Refers to the package size/style (Half-size DIP). * **1**: Refers to the voltage (typically 5V). * **T**: Tri-state enable/disable function (allows the output to be disconnected without powering down). * **F**: Operating Temperature Range (Industrial: -40°C to +85°C). * **G**: Frequency Stability (±100 ppm). * **-R**: RoHS Compliant (Lead-free). --- ### 3. Pin Configuration For the 4-pin half-size DIP package used by the MHO series, the standard pinout is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Tri-state / NC | High or Open = Output Active; Low = High Impedance | | **7** | Case Ground | Connected to the metal cover for shielding | | **8** | Output | The generated clock signal (Square wave) | | **14** | $V_{dd}$ | Positive power supply input (+5V) | --- ### 4. Key Features * **Tri-state Functionality:** Pin 1 allows the oscillator output to be disabled, which is useful for system testing or reducing power consumption when the clock is not needed. * **Hermetically Sealed:** The metal package is vacuum-sealed to protect the quartz crystal from environmental humidity and contaminants. * **Wide Temperature Range:** The "F" rating makes it suitable for outdoor or harsh industrial environments. ---
