Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Frequency** | 2.00 MHz | | **Frequency Tolerance** | ±0.5% | | **Resonant Impedance** | 80 Ω (max) | | **Load Capacitance** | 15 pF (Built-in) | | **Operating Temperature** | -20°C to +80°C | | **Package / Case** | SMD (Surface Mount Device) | | **Dimensions** | 7.20mm x 3.00mm x 1.60mm | --- ### 2. Core Features * **Built-in Load Capacitors:** This part features internal load capacitors, eliminating the need for two external capacitors on the PCB. This saves space and reduces the Bill of Materials (BOM) cost. * **Small Footprint:** Its surface-mount design is optimized for high-density mounting. * **High Stability:** While not as precise as a quartz crystal, it offers better stability and faster startup times than standard RC (Resistor-Capacitor) oscillators. * **Cost-Effective:** It provides a middle-ground solution between low-cost RC oscillators and high-precision quartz crystals. --- ### 3. Pin Configuration and Circuit Integration The CSTCC series typically features a **3-terminal** layout: 1. **Input:** Connected to the oscillator input of the MCU. 2. **Ground (GND):** The center pin is connected to the common ground (essential for the internal capacitors). 3. **Output:** Connected to the oscillator output of the MCU. --- ### 4. Common Applications * **Microcontrollers:** Serving as the clock source for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Used in remote colors, home appliances (washers, microwaves), and toys. * **Industrial Equipment:** General-purpose timing for non-critical communication and processing. --- ### 5. Part Number Breakdown (Nomenclature) * **CSTCC:** Product Series (CERALOCK® SMD type with built-in caps). * **2M00:** Nominal Frequency (2.00 MHz). * **G:** Frequency Tolerance/Stability code. * **53:** Individual Specification code (Load capacitance/Dimensions). * **Z-R0:** Packaging code (Tape and Reel).
