Key Component Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Series** | CERALOCK® CSTCE | | **Frequency** | 16.8000 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% | | **Load Capacitance** | Built-in (approx. 15pF) | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temperature** | -20°C to +80°C | | **Packaging** | Tape & Reel (T/R) | --- ### 2. Internal Structure and Technology The part is more than just a piece of ceramic; it is an integrated solution: * **Piezoelectric Ceramic:** Uses the mechanical vibration of a ceramic element to create a precise electronic frequency. * **Built-in Capacitors:** Unlike standard quartz crystals that require external load capacitors on the PCB, the "CST" series includes internal capacitors. This saves PCB space and simplifies the design. * **Three-Terminal Design:** It typically has three pads: 1. Input 2. Ground (Common) 3. Output --- ### 3. Application and Comparison This part is commonly found in consumer electronics, small appliances, and industrial controllers. #### Comparison: Ceramic Resonator vs. Quartz Crystal | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Start-up Time** | Very Fast | Slower | | **Cost** | Lower | Higher | | **Size** | Small (Integrated Caps) | Larger (Requires external caps) | --- ### 4. Part Number Breakdown The nomenclature reveals the specific characteristics: * **CSTCE**: Series (SMD type with built-in caps). * **16M8**: Frequency (16.8 MHz). * **V**: Frequency tolerance/stability code. * **53**: Individual specification code. * **-R0**: Packaging code (Reel).
