### Overview of CSTCW24M0X53R-R0 The **CSTCW24M0X53R-R0** is a specific surface-mount (SMD) **Ceramic Resonator** manufactured by **Murata Electronics**. It belongs to the CERALOCK® product line, which is designed to provide stable clock signals for microprocessors and other digital circuits. --- ### Technical Specifications The following table outlines the primary electrical and mechanical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 24.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% (over temperature) | | **Operating Temperature** | -20°C to +80°C | | **Internal Capacitance** | 15 pF (Built-in load capacitors) | | **Package Type** | SMD (4532 metric / 1812 imperial) | | **Package Dimensions** | 4.5 x 3.2 x 1.15 mm | | **Mounting Type** | Surface Mount | --- ### Key Internal Features 1. **Built-in Load Capacitors**: Unlike standard crystals that require two external capacitors to complete the oscillation circuit, this part has the load capacitors (15pF) integrated into the ceramic package. This saves PCB space and reduces component count. 2. **Ceramic Material**: It uses the mechanical resonance of piezoelectric ceramics. While less precise than quartz crystals, ceramic resonators are cheaper, smaller, and have a faster start-up time. 3. **Standard 3-Terminal Pinout**: * **Pin 1:** Input (to MCU) * **Pin 2:** Ground (GND) * **Pin 3:** Output (to MCU) --- ### Typical Applications This part is commonly used as a clock source for: * **Microcontrollers:** Providing the heartbeat for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Used in remote controls, home appliances, and toys. * **USB Peripherals:** Often used in low-speed or full-speed USB devices where a 24MHz clock is required. * **Communication Equipment:** Suitable for non-critical timing in networking hardware. --- ### Advantages vs. Disadvantages | Advantage | Disadvantage | | :--- | :--- | | Integrated capacitors save space. | Lower frequency accuracy than quartz crystals. | | High resistance to vibration and shock. | Stability varies more with temperature changes. | | Cost-effective for high-volume production. | Not suitable for high-precision timing (e.g., RTC). |
