The **CSTCC10M0G53-R0** is a miniature, surface-mount ceramic resonator manufactured by Murata Electronics. It is part of the CERALOCK® line, widely used for providing clock signals to microprocessors and other digital circuits. --- ## 1. Technical Specifications The following table outlines the key electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Frequency** | 10.0 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 3-SMD (Non-Standard) | | **Built-in Capacitance** | 15 pF | | **Resonant Impedance** | 50 Ohms (Max) | --- ## 2. Key Features ### Internal Load Capacitors One of the most significant features of this part is the **built-in load capacitance**. Unlike traditional quartz crystals that require two external capacitors to stabilize the oscillation, the CSTCC series integrates these into the ceramic package. * **Space Saving:** Reduces the footprint on the PCB. * **Cost Effective:** Eliminates the need for two additional SMT components. ### Physical Durability Ceramic resonators are generally more robust than quartz crystals regarding physical shock and vibration, making them suitable for consumer electronics and industrial tools. ### Frequency Stability While ceramic resonators are less precise than quartz crystals (±0.5% vs. ±0.001%), they are more than sufficient for: * USB-Low speed communication. * General-purpose microcontrollers (MCUs). * Remote controls and toys. --- ## 3. Pin Configuration and Circuitry The device typically features three terminals: 1. **Input:** Connected to the XTAL_IN pin of the MCU. 2. **Ground:** The center pin, connected to the system ground. 3. **Output:** Connected to the XTAL_OUT pin of the MCU. ```mermaid graph LR MCU_XTAL1 --- Pin1[Input] GND --- Pin2[Center Ground] MCU_XTAL2 --- Pin3[Output] ``` --- ## 4. Typical Applications * **Microcontrollers:** Serving as the main system clock for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Washing machines, microwave ovens, and air conditioners. * **Peripherals:** Computer mice, keyboards, and simple USB devices.
