The **CSTCE13M5G52-R0** is a small-form-factor ceramic resonator produced by **Murata Electronics**. It is part of the CERALOCK® family, designed to provide a stable clock signal for microcontrollers and other digital circuits without the need for external load capacitors. --- ### 1. General Specifications The following table summarizes the key electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 13.500 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.2% | | **Load Capacitance** | 10 pF (Internal) | | **Operating Temperature** | -20°C to +80°C | | **Package / Case** | 3.2 x 1.3 mm (SMD) | | **Mounting Type** | Surface Mount | --- ### 2. Key Internal Features The "V01" suffix usually refers to specific packaging or a minor revision in Murata's production line, but the core technology remains consistent: * **Built-in Load Capacitors:** This part features three terminals. The center pin is grounded, and the internal capacitors are integrated into the package. This saves PCB space and reduces the Bill of Materials (BOM) cost. * **Ceramic Technology:** Unlike quartz crystals, ceramic resonators utilize the mechanical resonance of piezoelectric ceramics. While slightly less accurate than quartz, they are more physically robust and start up faster. * **Small Footprint:** Its ultra-miniature size (3213 metric) makes it ideal for compact consumer electronics like remote controls, small appliances, and wearable devices. --- ### 3. Pin Configuration The device has 3 pads on the bottom for surface mounting: | Pad Number | Function | Description | | :---: | :--- | :--- | | **1** | Input | Connects to the XTAL_IN of the MCU | | **2** | Ground | Must be connected to the system ground | | **3** | Output | Connects to the XTAL_OUT of the MCU | --- ### 4. Circuit Application In a typical microcontroller application, the resonator is placed between the oscillator pins. No external capacitors are required because of the internal 10pF load. ```c // Typical Schematic Representation // [MCU_OSC_IN] ---- [Pad 1] // [GND] ---- [Pad 2] (Center) // [MCU_OSC_OUT] ---- [Pad 3] ```
