## Overview of CSTCE9M00G52-R0 The **CSTCE9M00G52-R0** is a specific model of a **Ceramic Resonator** manufactured by **Murata Electronics**. It belongs to the **CERALOCK®** product line. These components are used to provide a stable clock signal for microcontrollers, microprocessors, and other digital ICs. --- ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Nominal Frequency** | 9.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Oscillation Frequency Shift** | ±0.3% (Over Temperature) | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | 10 pF (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 3.2 x 1.3 mm (Small Cap Chip Type) | --- ### Key Features and Internal Components #### 1. Built-in Load Capacitors Unlike standard crystals that often require external capacitors (C1 and C2) to complete the oscillation circuit, the CSTCE series features **built-in load capacitors**. This reduces the component count on the PCB and saves space. #### 2. Piezoelectric Material The part is made of high-stability piezoelectric ceramics. When an electrical signal is applied, the material vibrates mechanically at a specific frequency (9 MHz), which is then converted back into an electrical clock signal. #### 3. Small Form Factor The "CE" in the part number indicates it is part of the small-cap chip type, making it ideal for high-density circuit boards used in consumer electronics. --- ### Common Applications * **Microcontrollers:** Serving as the external clock source for MCUs in home appliances. * **Communication Equipment:** Providing timing for low-speed data transfers. * **Automotive/Industrial:** Used in non-safety critical control units (though specific "A" grade versions are usually preferred for automotive). --- ### Part Number Breakdown | Segment | Meaning | | :--- | :--- | | **CST** | Ceramic Resonator (CERALOCK®) | | **CE** | Small-cap SMD type | | **9M00** | Frequency (9.00 MHz) | | **G** | Frequency tolerance / Temperature characteristic code | | **52** | Specific internal design code | | **-R0** | Packaging (Plastic taping, 180mm reel) |
