The **CSTCC3M52G53-R0** is a specific model of a **Ceramic Resonator** manufactured by Murata Electronics. These components are used in electronic circuits as a clock source or timing element, serving as a lower-cost, smaller-sized alternative to quartz crystals. --- ### 1. Key Technical Specifications Based on the part number nomenclature, here are the primary technical characteristics: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 3.52 MHz | | **Series** | CSTCC (Standard small SMD type) | | **Resonant Impedance** | Max 50 $\Omega$ (Standard for this range) | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Built-in Capacitance** | 15pF (Standard for "G" type) | | **Packaging** | Tape & Reel (R0 suffix) | --- ### 2. Functional Components The "V01" designation usually refers to a specific version or production variation (often specific to the manufacturer's internal revision tracking). Internally, the part consists of: 1. **Piezoelectric Ceramic Element:** The core material that vibrates at a specific frequency when an electrical voltage is applied. 2. **Built-in Load Capacitors:** This model belongs to the "CST" family, which includes internal capacitors. This eliminates the need for two external capacitors on the PCB, saving space. 3. **Alumina Substrate:** The ceramic base that holds the electrodes and provides mechanical stability. --- ### 3. Pin Configuration & Application The device typically features **three terminals** in a Surface Mount Device (SMD) package: * **Pin 1:** Input (to Oscillator In) * **Pin 2:** Ground (Common for internal capacitors) * **Pin 3:** Output (to Oscillator Out) #### Common Uses: * **Microcontrollers:** Providing the system clock for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Remote controls, toys, and small appliances where extreme precision (like that of a quartz crystal) is not required. * **Automotive/Industrial:** Simple timing for secondary control units. --- ### 4. Comparison: Ceramic Resonator vs. Quartz Crystal | Feature | Ceramic Resonator (CSTCC) | Quartz Crystal | | :--- | :--- | :--- | | **Cost** | Lower | Higher | | **Size** | Smaller (Built-in caps) | Larger (Requires external caps) | | **Start-up Time** | Very Fast | Slower | | **Accuracy** | Moderate (0.1% to 0.5%) | High (ppm levels) |
