The **SFECF10M7FA00S0-R0** is a high-performance **Ceramic Filter** manufactured by **Murata Electronics**. It is specifically designed for FM intermediate frequency (IF) processing in various communication and audio devices. --- ### 1. General Specifications This component belongs to the CERALOCK®/Ceramic Filter family and is primarily used for filtering specific frequencies while suppressing noise. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Center Frequency** | 10.7 MHz | | **3dB Bandwidth** | 280 kHz ± 50 kHz | | **Insertion Loss** | 3.0 dB max (at minimum loss point) | | **Input/Output Impedance** | 330 $\Omega$ | | **Package Type** | Surface Mount (SMD) | | **Operating Temperature** | -20°C to +80°C | --- ### 2. Key Features * **Small Footprint:** Its SMD design allows for high-density mounting in compact consumer electronics. * **High Selectivity:** Excellent attenuation characteristics outside the passband to ensure clear signal reception. * **Stability:** High thermal and mechanical stability compared to traditional LC filters. * **Lead-Free:** Compliant with RoHS regulations. --- ### 3. Pin Configuration and Internal Structure The device typically features a 3-terminal structure. 1. **Input (Pin 1):** Where the 10.7MHz IF signal enters. 2. **Ground (Pin 2):** Common ground for shielding and reference. 3. **Output (Pin 3):** Where the filtered signal exits to the next stage (usually the FM demodulator). --- ### 4. Typical Applications The SFECF series is standard in the following sectors: * **Home Audio:** FM Stereo tuners and Hi-Fi systems. * **Car Electronics:** Car radio receivers (infotainment systems). * **Communications:** Portable radio transceivers and wireless equipment. --- ### 5.
