Technical Specifications Below are the primary technical parameters associated with this specific part series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Quartz Crystal (SMD) | | **Package Size** | 8.0 x 4.5 x 1.4 mm | | **Frequency Range** | 8.0 MHz to 100.0 MHz | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Load Capacitance** | Typically 18pF (Standard) | | **Frequency Tolerance** | ±30 ppm | | **Frequency Stability** | ±50 ppm | | **ESR (Equiv. Series Resistance)** | 40 - 100 Ohms (Frequency dependent) | --- ### 2. Key Features The "R/Q" designation often refers to specific automotive grade qualifications or reel packaging standards (Tape & Reel). Key features include: * **Low Profile:** The 1.4mm height makes it ideal for height-constrained applications like thin IoT devices or portable electronics. * **High Precision:** Offers tight frequency stability and tolerance, essential for timing in communication protocols (UART, USB, Bluetooth). * **Sealing:** Hermetically sealed in a ceramic package with a metal lid, providing high reliability and resistance to environmental moisture. * **Automotive Grade (Q):** If the "Q" suffix follows AEC-Q200 standards, the part is stress-tested for harsh environments, including vibrations and temperature cycling. --- ### 3. Application Use Cases This crystal is commonly found in the following sectors: 1. **Consumer Electronics:** Microprocessor clocks for tablets and laptops. 2. **Industrial:** Sensors, programmable logic controllers (PLCs), and RF modules. 3. **Connectivity:** Fundamental clock source for Wi-Fi and Zigbee modules. 4. **Automotive:** (For 'Q' rated parts) Infotainment systems, engine control units, and navigation hardware. --- ### 4. Typical Circuit Integration In a typical Pierce Oscillator circuit, the crystal is connected across the input and output of an inverter (inside an MCU). ```cpp // Schematic representation of crystal integration [MCU_OSC_IN] ----+---- [Crystal] ----+---- [MCU_OSC_OUT] | | [C1] [C2] | | [GND] [GND] // Note: C1 and C2 are load capacitors, usually around 10-22pF. ``` ---
