The **CSTCE10M0G55Z-R0** is a specific surface-mount (SMD) ceramic resonator produced by **Murata Manufacturing Co., Ltd.** It belongs to the CERALOCK® family and is widely used for clock generation in microcontrollers. ### 1. Technical Specifications The following table summarizes the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 10.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -40°C to +125°C | | **Load Capacitance** | 33 pF (Built-in) | | **Package Type** | SMD (Small Cap Chip) | | **Dimensions** | 3.2 x 1.3 mm | | **Mounting Type** | Surface Mount | --- ### 2. Key Features and Construction * **Built-in Capacitance:** Unlike quartz crystals that often require external capacitors to form an oscillation circuit, this resonator has internal 33 pF capacitors. This saves PCB space and simplifies the design. * **Piezoelectric Material:** It utilizes the mechanical resonance of piezoelectric ceramics. While less precise than quartz, ceramic resonators are more robust and cost-effective. * **High Reliability:** The "G" series is automotive-grade (AEC-Q200 compliant in many variations), meaning it can withstand high vibration and wide temperature fluctuations. * **Standard Footprint:** It typically features a 3-terminal design: 1. **Input** (Oscillator In) 2. **Ground** (Common) 3. **Output** (Oscillator Out) --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal | | :--- | :--- | :--- | | **Precision** | Moderate (±0.5%) | High (±10ppm to ±50ppm) | | **Cost** | Low | Higher | | **Start-up Time** | Very Fast | Slower | | **Integration** | Capacitors included | Requires external capacitors | --- ### 4. Common Applications Due to its 10 MHz frequency and internal capacitors, this part is commonly found in: * **Microcontroller Clocks:** Providing the heartbeat for 8-bit or 16-bit MCUs. * **Automotive Electronics:** Engine control units (ECU), cluster displays, and sensor modules. * **Industrial Equipment:** PLC controllers and measurement devices. * **Consumer Electronics:** Remote controls and appliances where precise timing is needed but extreme quartz accuracy is not mandatory.
