## Technical Overview of SFECF10M7DF00S0-R0 The **SFECF10M7DF00S0-R0** is a high-performance **Ceramic Filter** manufactured by **Murata Electronics**. It belongs to the SFECF series, which is specifically designed for surface-mount applications in communication equipment. ### 1. Core Functionality This component is a band-pass filter used primarily in the **Intermediate Frequency (IF)** stage of FM receivers. Its role is to allow signals within a specific frequency range (around 10.7 MHz) to pass through while significantly attenuating noise and interference from adjacent channels. --- ### 2. Key Specifications | Parameter | Specification | |:---|:---| | **Center Frequency (fc)** | 10.700 MHz | | **3dB Bandwidth** | 150 kHz ± 40 kHz | | **Insertion Loss** | 4.0 dB max. | | **Stop Band Attenuation** | 25 dB min. (at fc ± 300 kHz) | | **Input/Output Impedance** | 330 $\Omega$ | | **Operating Temperature** | -20°C to +80°C | | **Package Type** | SMD (Surface Mount Device) | --- ### 3. Component Characteristics * **Small Footprint:** Its compact SMD design allows for high-density mounting on PCBs, making it ideal for portable electronics. * **Piezoelectric Technology:** It utilizes the piezoelectric effect of ceramics to achieve high frequency selectivity and stability. * **Flat Profile:** The "F" in the series name often denotes a flat-type lead or low-profile structure to minimize vertical space usage. * **Reliability:** Designed for high mechanical strength and resistance to thermal stress during soldering. --- ### 4. Typical Applications 1. **FM Radio Receivers:** Used in the IF section of high-fidelity tuners. 2. **Wireless Communication:** Employed in transceivers for narrowband data transmission. 3. **Audio Equipment:** Found in home theater systems and car stereos to ensure clear signal reception. ### 5. Part Number Breakdown The part number can be decoded roughly as follows: * **SFE:** Surface Mount Ceramic Filter. * **CF:** Specific series designation (often relates to bandwidth/shape). * **10M7:** Center frequency of 10.7 MHz. * **DF00:** Design/Tolerance code (specifies bandwidth characteristics). * **R0:** Packaging code (indicates Reel/Tape packaging).
