Technical Specifications Below are the primary technical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Series** | CSBFB (Standard type) | | **Nominal Frequency** | 1.000 MHz (1000 kHz) | | **Frequency Tolerance** | ±0.5% | | **Resonant Impedance** | 40 $\Omega$ (Max) | | **Operating Temperature** | -20°C to +80°C | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 2-SMD, Non-Standard (approx. 5.0mm x 5.0mm) | --- ### 2. Key Features and Construction The CSBFB series utilizes the mechanical resonance of piezoelectric ceramics. Compared to quartz crystals, these resonators offer specific advantages: * **Miniaturization:** High-density mounting is possible due to the small surface-mount package. * **Built-in Load Capacitance:** While some models in the series have built-in capacitors, the CSBFB series generally requires external capacitors unless specified otherwise in the sub-code. * **Stability:** Offers excellent frequency stability and high Q-factor compared to standard LC circuits. * **Cost-Effective:** Generally more affordable than high-precision quartz crystals for applications that can tolerate a slightly higher frequency drift. --- ### 3. Application Use Cases This specific 1.000 MHz resonator is typically used in timing circuits where extreme precision (like a real-time clock) is not required, but stability is essential. 1. **Microcontrollers (MCUs):** Providing the external clock source for 8-bit or 16-bit MCUs. 2. **Consumer Electronics:** Used in remote controls, home appliances (microwaves, washing machines), and toys. 3. **Communication Equipment:** Local oscillators in low-frequency communication devices. --- ### 4. Circuit Diagram (Simplified) When integrating the CSBFB1M00J58-R0 with an IC, the typical configuration involves two external load capacitors ($C_1$ and $C_2$) and a feedback resistor ($R_f$): ```text +-------------------------+ | IC | | [OSC_IN] [OSC_OUT]| +------|------------|-----+ | | +----[ R_f ]---+ | | [Resonator] | | | C1 ---+--- C2 | | | (GND) (GND) ```
