The **MHO+52TBD-R** is a specific part number belonging to a series of **high-stability crystal oscillators** manufactured by MtronPTI. These components are used to generate a precise frequency signal for electronic circuits. ### 1. Part Number Breakdown While manufacturer coding can vary slightly by production year, the MHO+ series typically follows this convention: | Code Segment | Meaning | Specification Details | | :--- | :--- | :--- | | **MHO+** | Series Name | High-reliability, HC-49/U or Large Thru-hole Oscillator | | **5** | Voltage Supply | Typically indicates **5.0V DC** operation | | **2** | Stability/Temp | Represents frequency stability (often ±50ppm) | | **T** | Output Type | **TTL / CMOS** compatible output | | **BD** | Temperature Range | Usually denotes **-40°C to +85°C** (Industrial) | | **R** | RoHS Compliance | Indicates the part is **Lead-Free / RoHS compliant** | --- ### 2. Technical Specifications These oscillators are "active" components, meaning they require a power source to function, unlike passive crystals. * **Frequency Range:** Usually customized (often between 1.0 MHz to 150 MHz). * **Package Type:** 14-pin DIP (Dual In-line Package) metal canister (Full Size). * **Operating Voltage:** 5.0V (Standard for the "5" designation). * **Output Load:** 15pF to 50pF. * **Symmetry/Duty Cycle:** 40/60% to 45/55%. --- ### 3. Pin Configuration (14-Pin DIP Package) Standard 14-pin DIP oscillators only utilize 4 physical pins in the corners: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | +5V Power Supply | --- ### 4. Common Applications Due to its rugged through-hole design and 5V logic, this part is commonly found in: * **Legacy Computing:** Older industrial motherboards and controllers. * **Telecommunications:** Timing synchronization in networking hardware. * **Industrial Controls:** Systems requiring high reliability in harsh temperature environments. * **Test Equipment:** Signal generators and measurement devices.
