## CSTCC3M00G56-R0: Electronic Component Overview The **CSTCC3M00G56-R0** is a **Ceramic Resonator** manufactured by **Murata Electronics**. It belongs to the CERALOCK® family, designed to provide a stable clock signal for microprocessors and other integrated circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Frequency** | 3.00 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% | | **Built-in Capacitance** | 47 pF (Internal Load Capacitors) | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 3-SMD, Non-Standard (7234 metric) | | **Operating Temperature** | -20°C to +80°C | | **Dimensions** | 7.20mm L x 3.40mm W x 1.80mm H | --- ### 2. Physical Structure and Pins The CSTCC series is distinct because it is a **3-terminal device**. Unlike standard 2-pin crystals that require external load capacitors, this component integrates them internally. * **Pin 1 (Input):** Connected to the oscillator input of the IC. * **Pin 2 (Ground):** The center pin, connected to the system ground. * **Pin 3 (Output):** Connected to the oscillator output of the IC. --- ### 3. Core Features * **Integrated Load Capacitors:** By including internal 47pF capacitors, it saves significant PCB space and reduces the total component count. * **High Stability:** While not as precise as a quartz crystal, it offers significantly better stability than an RC (Resistor-Capacitor) oscillator. * **Cost-Effective:** Generally cheaper than quartz crystals for applications where extreme frequency precision (like high-speed communication) is not required. * **Small Footprint:** The "CC" designation refers to a specific leaded-chip form factor suitable for automated pick-and-place assembly. --- ### 4. Typical Applications The CSTCC3M00G56-R0 is commonly found in: 1. **Microcontrollers:** Providing the primary clock source for 8-bit or 16-bit MCUs. 2. **Consumer Electronics:** Remote controls, white goods (washers/dryers), and toys. 3. **Automotive (Non-Safety):** Entertainment systems or dashboard displays (note: check for AEC-Q200 qualification for specific automotive use). 4. **Peripheral Equipment:** Computer mice, keyboards, and basic USB devices. ---
