    ## Overview of SFECF10M7EA00-R0 The **SFECF10M7EA00-R0** is a high-performance **Ceramic Filter** manufactured by **Murata Electronics**. It belongs to the CERAIL® series and is specifically designed for FM intermediate frequency (IF) processing. ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Center Frequency (fo)** | 10.700 MHz | | **3dB Bandwidth** | 190 kHz ± 30 kHz | | **Insertion Loss** | 3.0 dB to 4.5 dB (max) | | **Input/Output Impedance** | 330 $\Omega$ | | **Operating Temperature** | -20°C to +80°C | | **Package Type** | Surface Mount Device (SMD) | | **Mounting Style** | 3-terminal (In, Out, Ground) | --- ### 2. Functional Description This component is a **piezoelectric ceramic filter**. It utilizes the energy-trapped thickness-shear vibration mode of the ceramic element. #### Core Functions: * **Frequency Selection:** It allows the 10.7 MHz IF signal to pass while suppressing unwanted noise and adjacent channel interference. * **Impedance Matching:** Designed to work with standard 330 $\Omega$ circuits commonly found in FM radio chipsets. * **Miniaturization:** Its thin, flat structure is optimized for high-density surface mounting in modern mobile devices. --- ### 3. Physical Dimensions & Packaging The "R0" suffix indicates the packaging style, typically referring to **Tape & Reel** (180mm) for automated pick-and-place assembly. * **Size:** Small form factor (Standard 3.45 x 3.1 mm footprint). * **Profile:** Low-profile design, making it suitable for thin consumer electronics. --- ### 4. Common Applications The SFECF10M7EA00-R0 is primarily used in communication equipment where compact size and stability are critical: 1. **Consumer Electronics:** FM radio receivers in smartphones and portable media players. 2. **Automotive:** Car audio systems and infotainment units. 3. **Wireless Modules:** Low-power FM transmitters and wireless headphone base stations. --- ### 5. Part Number Breakdown * **SFECF:** Series name (SMD Ceramic Filter for FM). * **10M7:** Center frequency (10.7 MHz). * **EA00:** Design code / Bandwidth characteristics. * **R0:** Packaging code (Embossed Taping).
