Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 16.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Built-in Load Capacitance** | 15 pF | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 3.2 x 1.3 mm (1206 size) | | **Frequency Aging** | ±0.3% (over 10 years) | --- ### 2. Functional Components This component is more than just a raw ceramic slab; it is a three-terminal device designed for "plug-and-play" oscillation. * **Ceramic Element:** Uses the mechanical resonance of piezoelectric ceramics to oscillate at 16MHz. * **Built-in Load Capacitors:** Unlike standard crystals that require two external capacitors to ground, this part has the capacitors integrated inside the package. * **Three-Terminal Design:** 1. **Input:** Connected to the oscillator circuit (OSC_IN). 2. **Ground:** Connected to the system ground. 3. **Output:** Connected to the oscillator circuit (OSC_OUT). --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal While both provide timing, the CSTCE series occupies a middle ground between RC circuits and Quartz Crystals. | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal (XTAL) | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Startup Time** | Very Fast | Slower | | **Cost** | Low | Higher | | **Size** | Small (Built-in caps) | Requires external caps | | **Best Use** | Microcontrollers, USB 1.1 | High-speed RF, Ethernet | --- ### 4. Application Circuit Example Because the capacitors are internal, the wiring is simplified. ```text Microcontroller +---------------+ | | | OSC_IN | <-----+--- [ Terminal 1 ] | | | | OSC_OUT | <-----+--- [ Terminal 3 ] | | | | GND | <--------- [ Terminal 2 ] +---------------+ ``` --- ### 5. Part Number Breakdown (Naming Convention) * **CSTCE**: Series (SMD type with built-in capacitors). * **16M9**: Frequency (16.9... MHz notation, though standard 16.0MHz often follows this code block). * **V**: Frequency tolerance/stability code. * **53**: Individual specification code (Internal Murata designator). * **R0**: Packaging (Plastic tape ø180mm reel).
