## CSTCC10M0G53A-R0: Electronic Component Overview The **CSTCC10M0G53A-R0** is a ceramic resonator from the **CERALOCK®** product line, manufactured by **Murata Manufacturing Co., Ltd.** It is primarily used as a timing clock source for microprocessors and other digital circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Resonant Frequency** | 10.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Frequency Stability** | ±0.3% (over temperature range) | | **Internal Capacitance** | 15 pF (Built-in load capacitors) | | **Package Type** | Surface Mount (SMD) | | **Mounting Style** | 7.2mm x 3.0mm (standard CSTCC footprint) | --- ### 2. Functional Characteristics #### A. Ceramic Resonator Technology Unlike quartz crystals which use silicon dioxide, this part uses high-stability piezoelectric ceramics. While slightly less precise than quartz, it offers faster start-up times and a smaller physical footprint. #### B. Built-in Load Capacitors The "CST" prefix indicates that this device includes **built-in load capacitors**. * **Advantage:** This eliminates the need for two external capacitors on the PCB, saving board space and reducing the Bill of Materials (BOM) cost. * **Circuitry:** It typically features three terminals: Input, Ground, and Output. #### C. Durability and Stability * **Aging:** Very low frequency drift over time. * **Mechanical:** High resistance to vibration and shock compared to delicate glass-sealed crystals. --- ### 3. Part Number Breakdown The Murata part numbering system conveys specific details: * **CSTCC**: Series name (SMD type with built-in capacitance). * **10M0**: Frequency (10.0 Megahertz). * **G**: Frequency tolerance (G = ±0.5%). * **53**: Load capacitance code (5 indicates 15pF). * **A**: Individual specification code. * **-R0**: Packaging code (Plastic taping, 2000 pcs/reel). --- ### 4. Common Applications 1. **Microcontrollers:** Serving as the external clock source for MCUs in consumer electronics. 2. **Peripherals:** Used in USB hubs, keyboards, and printers. 3. **Automotive (Non-Safety):** Car audio systems and dashboard displays. 4. **Home Appliances:** Control timing for washing machines, microwaves, and AC units. ---
