The **MHO+78FBD-R** is a specific part number typically associated with **Crystal Oscillators**, specifically those manufactured by companies like **MtronPTI**. This component belongs to the "MHO" series, which are high-reliability, metal-can-packaged clock oscillators. --- ## Technical Specifications Overview The alphanumeric code provides specific details about the component's electrical characteristics. Below is a breakdown of the typical parameters for this series: | Parameter | Specification Details | | :--- | :--- | | **Package Type** | 14-pin DIP (Full Size) Metal Can | | **Output Type** | HCMOS / TTL Compatible | | **Voltage Supply** | Typically 5.0V (Standard for +78 series) | | **Operating Temperature** | Often rated for Industrial or Military ranges | | **Frequency Stability** | Generally ±100ppm to ±25ppm (depending on suffix) | | **RoHS Status** | The "R" suffix typically denotes **RoHS Compliant** | --- ## Key Features ### 1. Robust Housing The "Metal Can" (DIP) package provides excellent electromagnetic interference (EMI) shielding. This makes it ideal for environments where high precision is required and electronic noise must be minimized. ### 2. Through-Hole Mounting Unlike modern SMD (Surface Mount Device) oscillators, the FBD-R series uses through-hole pins. This is preferred for: * Prototyping on breadboards or stripboards. * Legacy hardware repairs. * High-vibration environments where through-hole joints offer better mechanical strength. ### 3. Stability and Precision These oscillators are "Active" components, meaning they contain the internal quartz crystal plus the oscillation circuitry. You only need to provide power (VCC and Ground) to receive a steady square wave output. --- ## Part Number Breakdown (Typical) While specific internal catalogs may vary slightly, the nomenclature usually follows this logic: * **MHO**: Series identifier (Mtron High-Output/Metal Hermetic). * **+**: Often indicates a lead-free or specific voltage designation. * **78**: Frequency stability and operating temperature code. * **FBD**: Internal manufacturer package and output wave-shape code. * **R**: **RoHS Compliant** (Lead-free). --- ## Common Applications * **Microprocessor Clocks:** Providing the "heartbeat" for CPUs and MCUs. * **Telecommunications:** Timing for data transmission equipment. * **Industrial Control:** Reliable timing for PLC (Programmable Logic Controllers). * **Test & Measurement:** Used in frequency counters and signal generators.
