The part number **M2AS1-5434-R2SLASHQ** refers to a specific, high-reliability electromagnetic component, typically a **Crystal Oscillator** or a **Crystal Unit** manufactured for defense, aerospace, or space-grade applications. Below is a breakdown of the electronic specifications and characteristics associated with this part numbering convention (often seen in products by manufacturers like *Microchip/Vectron* or *MtronPTI*). --- ### 1. Component Specification Overview | Feature | Specification Details | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (XO) or Crystal Unit | | **Package Type** | Surface Mount Device (SMD) | | **Common Frequency Range** | Generally 1 MHz to 100+ MHz (specific to custom tuning) | | **Operating Voltage** | Typically 3.3V or 5.0V (Standard logic levels) | | **Screening Level** | High-Reliability / Military Grade | | **Output Type** | CMOS, HCMOS, or TTL compatible | --- ### 2. Part Number Breakdown (Functional Analysis) While part numbering schemes vary by manufacturer, this specific string follows a standard aerospace/military logic: * **M2AS1 / M2**: Usually designates the series and package size (e.g., 5x7mm or 3.2x5mm ceramic leadless chip carrier). * **5434**: This is often a internal code for the **center frequency** or a specific circuit configuration (load capacitance and drive level). * **R2**: This typically refers to the **Frequency Stability**. For instance, it may indicate ±20ppm or ±50ppm over the operating temperature range. * **SLASHQ (/Q)**: This is the most critical suffix. It indicates **Quality Screening**. * It often stands for **MIL-PRF-38534** or **Class Q** reliability standards. * This includes rigorous testing such as burn-in, thermal shock, and vibration testing. --- ### 3. Key Electronic Characteristics #### A. Frequency Stability This part is designed to maintain a precise clock signal despite environmental changes. The "R2" designation implies high stability, which is necessary for synchronized communication systems and timing circuits. #### B. Environmental Hardening Because of the `/Q` rating, these parts are built to withstand: * **Mechanical Shock:** Resistance to high G-force impacts. * **Operating Temperature:** Often rated for the full military range of **-55°C to +125°C**. * **Hermetic Sealing:** The internal quartz crystal is sealed in a vacuum or inert gas to prevent aging caused by oxidation. #### C. Power Consumption Designed for low-power operation, these components typically draw current in the range of 10mA to 30mA, depending on the frequency and output load. --- ### 4. Typical Applications * **Avionics:** Flight control computers and cockpit displays. * **Defense:** Guidance systems for missiles or tactical radios. * **Space:** Satellite telemetry and onboard data handling where "Radiation Tolerant" (Rad-Hard) components are preferred. ---
