## Overview of CSTCE16M0V51Z-R0 The **CSTCE16M0V51Z-R0** is a ceramic resonator produced by **Murata Electronics**. It belongs to the CERALOCK® family, which uses the mechanical resonance of piezoelectric ceramics to provide a stable frequency for electronic circuits. It is commonly used as a cost-effective alternative to quartz crystals. --- ### Technical Specifications | Parameter | Value | | :--- | :--- | | **Frequency** | 16.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Loading Capacitance** | 5 pF (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 1206 (3213 Metric) | | **Dimensions** | 3.20mm x 1.30mm | --- ### Key Electronic Features 1. **Built-in Load Capacitors**: Unlike standard crystals that require external capacitors (C1 and C2) to oscillate, this component has integrated capacitors. This saves PCB space and reduces the component count. 2. **Piezoelectric Material**: It utilizes the mechanical vibration of a ceramic element. While less precise than quartz, it offers faster start-up times and high vibration resistance. 3. **Frequency Stability**: With a tolerance of ±0.5%, it is suitable for clocking microcontrollers (MCUs) in consumer electronics, but not recommended for high-precision timing like GPS or high-speed RF. 4. **SMD Packaging**: Designed for automated pick-and-place assembly and reflow soldering. --- ### Pin Configuration (3-Terminal) | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Input | Connected to the MCU's XTAL_IN / OSC1 | | **2** | Ground | Common Ground for internal capacitors | | **3** | Output | Connected to the MCU's XTAL_OUT / OSC2 | --- ### Typical Applications * **Microcontrollers**: Clock generation for 8-bit or 16-bit MCUs. * **Consumer Electronics**: Remote controls, toys, and small appliances. * **Automotive Accessory**: Non-safety critical systems like infotainment or power windows (though "Z" series is usually general purpose). * **USB Peripherals**: Low-speed USB communication devices. ---
