## Overview of CSTCE8M00G52A-R0 The **CSTCE8M00G52A-R0** is a specific model of a **Ceramic Resonator** manufactured by **Murata Electronics**. It belongs to the CERALOCK® family, which are high-reliability components used to provide a stable clock signal for microcontrollers and other digital circuits. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 8.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.2% | | **Capacitance (Built-in)** | 10 pF (Internal load capacitors) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 3.2 x 1.3 mm (1205 size) | | **Operating Temperature** | -40°C to +125°C | | **Product Series** | CSTCE_G (Automotive Grade available) | --- ### Key Features and Electronic Characteristics 1. **Built-in Load Capacitors:** This part is a "3-pin" resonator. Unlike a standard 2-pin crystal that requires external capacitors to form an oscillation circuit, this component has the capacitors integrated inside the package. This saves PCB space and reduces component count. 2. **Size and Form Factor:** The "CE" in the part number indicates a small SMD package (3.2 x 1.3 mm). It is designed for high-density mounting in compact electronic devices. 3. **High Reliability:** The CSTCE series is known for its mechanical robustness against vibration and shock compared to traditional quartz crystals. 4. **No Adjustment Required:** Because the capacitors are built-in, the oscillation circuit is generally stable upon installation without needing manual tuning of external values. --- ### Comparison: Ceramic Resonator vs. Quartz Crystal | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Cost** | Lower | Higher | | **Startup Time** | Faster | Slower | | **Durability** | High (Resistance to impact) | Lower (Fragile quartz) | --- ### Typical Applications * **Microcontrollers (MCU):** Providing the clock source for automotive body control units, industrial controllers, and consumer appliances. * **USB Peripherals:** Clocking for low-speed USB communication. * **Home Appliances:** Control boards for washing machines, microwave ovens, and air conditioners. ---
