The **CSTCE14M0V51-R0** is a specific model of a **Ceramic Resonator** manufactured by Murata Manufacturing. It belongs to the CERALOCK® family, which are high-precision components used to provide a clock signal for microcontrollers and other digital ICs. ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Nominal Frequency** | 14.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Initial Frequency Shift** | Within ±0.3% | | **Built-in Load Capacitance** | 5 pF (Internal) | | **Operating Temperature** | -20°C to +80°C | | **Package Type** | Surface Mount (SMD) | | **Size / Dimension** | 3.2mm x 1.3mm (Type 3213) | | **Mounting Style** | 3-Terminal SMD | --- ### 2. Internal Structure and Design Unlike a standard 2-pin crystal, this part is a **3-pin device**. This is because it includes **integrated load capacitors**. * **Pin 1:** Input * **Pin 2:** Ground (Common) * **Pin 3:** Output By integrating the capacitors inside the ceramic package, the part saves PCB space and reduces the external component count, as you do not need to add two discrete capacitors on the board. --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal It is important to understand where this part sits in terms of performance: | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±10ppm to ±50ppm) | | **Cost** | Low | Higher | | **Start-up Time** | Very Fast | Slower | | **Size** | Small (Integrated Caps) | Varies (External Caps needed) | --- ### 4. Typical Applications The CSTCE14M0V51-R0 is commonly used in consumer electronics where extreme precision (like a real-time clock) isn't required, but cost and space are critical: * **Microcontrollers (MCUs):** Providing the system clock for 8-bit or 16-bit processors. * **USB Peripherals:** Basic timing for non-high-speed USB devices. * **Home Appliances:** Control boards for washing machines or microwaves. * **Remote Controls:** General timing for signal modulation. --- ### 5. Part Number Breakdown The Murata part numbering system conveys specific details: * **CSTCE:** Product Series (SMD type with built-in caps). * **14M0:** Frequency (14.000 MHz). * **V:** Frequency thickness vibration mode. * **51:** Design/Capacitance code (indicates 5pF internal caps). * **-R0:** Packaging (Plastic tape/reel).
