Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Surface Mount Ceramic Filter (SMD) | | **Center Frequency (fo)** | 10.700 MHz | | **3dB Bandwidth** | 230 kHz ± 50 kHz | | **Insertion Loss** | 3.0 dB to 4.5 dB max | | **Input/Output Impedance** | 330 $\Omega$ | | **Operating Temperature** | -20°C to +80°C | | **Dimensions** | 3.45 x 3.10 x 1.40 mm | --- ### 2. Physical and Structural Parts This component is not a single electronic part but a composite device consisting of several internal structures: * **Piezoelectric Ceramic Element:** The core of the filter. It uses the piezoelectric effect to convert electrical signals into mechanical vibrations and back, filtering out frequencies outside the resonance range. * **Electrodes:** Thin layers of metal (usually silver or gold alloy) deposited onto the ceramic to provide electrical connection points. * **Ceramic Substrate/Case:** Provides the physical housing and protection for the internal vibrating element. * **Termination Pads:** The bottom pads are designed for Surface Mount Technology (SMT) reflow soldering. --- ### 3. Application and Usage The SFECF10M7GA00S0-R0 is primarily used in the following circuits: 1. **FM Receivers:** Acting as a band-pass filter to select the desired 10.7 MHz IF signal while rejecting noise and adjacent channel interference. 2. **Audio Tuners:** Used in high-end home audio systems where low distortion and precise bandwidth are required. 3. **Car Radio Systems:** Due to its compact SMD form factor, it is ideal for space-constrained automotive PCB designs. ### 4. Part Number Breakdown * **SFECF:** Series name (Surface Mount Ceramic Filter). * **10M7:** Center frequency (10.7 MHz). * **GA00:** Specific characteristics related to bandwidth and attenuation (in this case, standard 230kHz). * **R0:** Packaging code (indicates 180mm diameter plastic tape and reel). ---
