Technical Specifications Below is a breakdown of the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Oscillating Frequency** | 11.600 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% (over temperature range) | | **Operating Temperature** | -40°C to +85°C | | **Load Capacitance** | 33 pF (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 3.2 x 1.3 mm (1205 Case) | | **Packaging** | Tape and Reel (indicated by "-R0") | --- ### 2. Key Features and Components * **Built-in Capacitors:** Unlike standard quartz crystals that require external load capacitors, this ceramic resonator has built-in capacitors. This saves PCB space and reduces the Bill of Materials (BOM) cost. * **Three-Terminal Design:** It typically features three pads: 1. **Input** 2. **Ground** (Connected to the internal capacitors) 3. **Output** * **Small Form Factor:** The "E" series denotes a small, low-profile package suitable for modern, compact electronic devices. --- ### 3. Applications This part is commonly used in consumer electronics where high precision (like a crystal) isn't strictly necessary, but cost and space are critical factors: * **Microcontrollers (MCUs):** Providing the main system clock for 8-bit or 16-bit processors. * **USB Peripherals:** Clocking for low-speed USB devices. * **Automotive Electronics:** (Note: Check specific AEC-Q qualification for your use case). * **Home Appliances:** Control boards for washing machines, microwaves, and air conditioners. --- ### 4. Circuit Diagram Representation In a standard microcontroller circuit, the wiring is simplified because of the internal capacitors: ```text [ Microcontroller ] | XTAL1 XTAL2 | |___|_______|___| | | ______|_______|______ | [1] [2] [3] | | In GND Out | (CSTCE11M6G55Z-R0) |_________|___________| | Ground ``` ---
