Key Specifications | Feature | Specification | | :--- | :--- | | **Oscillation Frequency** | 16.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | 15 pF (Built-in) | | **Frequency Stability** | ±0.3% over temperature | | **Package / Case** | SMD (Small Cap Chip Type) | | **Dimensions** | 3.2 x 1.3 mm | --- ### 2. Functional Electronic Components The CSTCE series is unique because it integrates several electronic functions into a single surface-mount package: #### A. Piezoelectric Ceramic Element The core of the part is a ceramic material that utilizes the piezoelectric effect. When an electric field is applied, the material physically deforms, creating mechanical resonance at precisely **16 MHz**. #### B. Built-in Load Capacitors Unlike standard quartz crystals which often require two external capacitors (C1 and C2) to form an oscillation circuit, this part has **built-in capacitors**. * **Advantage:** Reduces the PCB footprint and lowers the total component count. * **Circuitry:** It is a 3-pin device (Input, Ground, Output). #### C. Equivalent Circuit Model Electronically, the resonator behaves like an RLC series circuit in parallel with a shunt capacitance: * **L1 (Motional Inductance):** Represents the mechanical mass in motion. * **C1 (Motional Capacitance):** Represents the stiffness of the ceramic. * **R1 (Motional Resistance):** Represents the energy loss (damping). --- ### 3. Application and Usage This part is commonly used in high-volume consumer electronics where a balance between cost and precision is required. * **Microcontrollers:** Provides the system clock for MCUs in appliances, automotive infotainment, and peripherals. * **Communication:** Used in USB controllers and low-speed data transmission where a ±0.5% tolerance is acceptable (Quartz crystals are more precise but more expensive). --- ### 4.
