The **CSTCE15M0V53Z-R0** is a specific type of electronic component known as a **Ceramic Resonator** with built-in load capacitors. It is manufactured by **Murata Electronics** and is part of the CERALOCK® family. Below is a detailed breakdown of its specifications and technical characteristics. --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Frequency** | 15.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Frequency Stability** | ±0.3% (over temp range) | | **Built-in Capacitance** | 15 pF | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 1206 (3.2mm x 1.3mm) | | **Resonant Impedance** | 40 Ω (Maximum) | --- ### 2. Key Components & Structure The CSTCE series is unique because it integrates three distinct functions into a single miniature package: 1. **Piezoelectric Element:** The core ceramic material vibrates at a specific frequency (15 MHz) when an electrical signal is applied. 2. **Built-in Load Capacitors:** Unlike standard quartz crystals that require two external capacitors to create an oscillation circuit, this part has them built-in. This saves PCB space and reduces component count. 3. **Terminal Configuration:** It typically features 3 terminals: * **Input/Output:** Connects to the oscillator pins of the MCU. * **Ground (Middle pin):** Connects to the circuit ground to complete the internal capacitor circuit. --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal It is important to understand where this part sits compared to a standard crystal. * **Cost:** Resonators like the CSTCE series are generally cheaper than quartz crystals. * **Size:** Extremely small footprint (3.2 x 1.3mm), making it ideal for compact consumer electronics. * **Accuracy:** While quartz crystals have higher precision (measured in ppm), ceramic resonators provide "good enough" accuracy (measured in %) for most microcontrollers and USB-interface applications. * **Startup Time:** Resonators have a faster startup time than crystals. --- ### 4. Part Number Breakdown * **CSTCE**: Series name (SMD type with built-in caps). * **15M0**: Frequency (15.0 MHz). * **V**: Frequency temperature characteristics. * **53**: Individual specification code. * **Z-R0**: Packaging code (Plastic tape and reel).
