Technical Specifications | Parameter | Specification | |:---|:---| | **Part Number** | CSBFB1M00J58-R1 | | **Oscillation Frequency** | 1.000 MHz (1000 kHz) | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% (over temperature) | | **Operating Temperature Range** | -20°C to +80°C | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | SMD, 5.0mm x 3.1mm | | **Capacitance** | External Capacitors Required (Not built-in) | --- ### 2. Functional Description Ceramic resonators like the CSBFB1M00J58-R1 function as the "heartbeat" of an electronic circuit. They utilize the mechanical resonance of piezoelectric ceramics to create a stable oscillating signal. * **Role in Circuit:** It is typically paired with an integrated circuit (IC) to provide a stable clock signal for microcontrollers, signal processors, or communication interfaces. * **Comparison to Crystals:** While Quartz crystals offer higher precision, Ceramic resonators are preferred for their: * Faster start-up times. * Smaller physical footprint. * Lower cost. * Higher resistance to mechanical shock and vibration. --- ### 3. Application Areas This specific 1.000 MHz resonator is commonly used in: 1. **Consumer Electronics:** Remote controls, clocks, and small appliances. 2. **Industrial Automation:** Low-speed data processing units. 3. **Communication:** Simple RF modules and timing for transmission protocols. 4. **Microcontrollers:** Serving as the external clock source for 8-bit or 16-bit MCUs. --- ### 4. Typical Circuit Configuration Since the **CSBFB** series (unlike the CST series) usually does **not** have internal load capacitors, an external circuit is required. ```c [IC Oscillator Pins] | (OSC1) (OSC2) | | |----| | |-------|Res |-----| | |on. | | _|_ |----| _|_ | C1| | C2| <-- External Load Capacitors |___| |___| | | GND GND ``` ---
