The **CSTCE10M0G52-R0** is a specific ceramic resonator manufactured by **Murata Electronics**. It belongs to the CERALOCK® series and is widely used for providing a stable clock signal to microprocessors and other digital circuits. --- ## 1. Technical Specifications The following table outlines the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 10.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | 10 pF (Built-in) | | **Package Type** | SMD (Surface Mount Device) | | **Dimensions** | 3.2mm x 1.3mm x 1.1mm | | **Resonant Impedance** | 40 Ω (Maximum) | --- ## 2. Key Features ### Built-in Load Capacitors One of the most significant features of this part is the **integration of load capacitors**. Traditional quartz crystals require two external capacitors to create an oscillation circuit. The CSTCE series includes these internally, which: * Saves PCB (Printed Circuit Board) space. * Reduces the Bill of Materials (BOM) cost. * Simplifies the circuit design. ### Ceramic Technology Unlike quartz crystals, ceramic resonators use the mechanical vibration of piezoelectric ceramics. While they are slightly less accurate than quartz (±0.5% vs. ±0.001%), they offer: * **Faster startup times.** * **Higher resistance to mechanical shock and vibration.** * **Lower cost.** --- ## 3. Pin Configuration & Circuit The device has 3 terminals: 1. **Input (Terminal 1):** Connected to the XTAL_IN of the MCU. 2. **Ground (Terminal 2):** Center pin, must be connected to the system ground. 3. **Output (Terminal 3):** Connected to the XTAL_OUT of the MCU. --- ## 4. Typical Applications This component is ideal for cost-sensitive applications where extreme precision (like high-speed networking) is not required: * **Microcontrollers:** Providing the clock for 8-bit or 16-bit MCUs. * **Consumer Electronics:** TV remote controls, toys, and small appliances. * **Automotive:** Body control modules (non-safety critical) and infotainment. * **Peripherals:** Mouse, keyboard, and USB-to-serial converters.
