The **SFECV10M7CQ0C01-R0** is a high-performance **Ceramic Filter** manufactured by Murata Electronics. It is specifically designed for FM intermediate frequency (IF) stages in radio communication devices. --- ### 1. Key Technical Specifications The part number follows a specific coding structure that defines its electrical characteristics: | Parameter | Specification | | :--- | :--- | | **Center Frequency (fo)** | 10.700 MHz | | **3dB Bandwidth** | 230 kHz ± 50 kHz | | **Insertion Loss** | 3.0 dB ± 2.0 dB | | **Selectivity** | 40 dB min. (at fo ± 400 kHz) | | **Input/Output Impedance** | 330 $\Omega$ | | **Package Type** | Surface Mount Device (SMD) | | **Operating Temperature** | -20°C to +80°C | --- ### 2. Functional Description This component utilizes the piezoelectric effect of ceramics to filter out noise and isolate the desired signal frequency. * **Selectivity:** It acts as a "gatekeeper" in the IF stage, ensuring that only the 10.7 MHz signal (common in FM broadcasting) passes through while suppressing adjacent channel interference. * **Chip Type (C-Series):** This specific series is known for its small footprint and thin profile, making it ideal for compact consumer electronics like smartphones, car stereos, and portable radios. --- ### 3. Part Number Breakdown (Nomenclature) Understanding the alphanumeric code helps identify the variant: * **SFECV:** Series name (SMD Ceramic Filter for FM). * **10M7:** Center frequency (10.7 MHz). * **CQ:** Indicates the bandwidth rank (standard 230kHz). * **01:** Design code. * **R0:** Indicates the packaging style (usually Tape & Reel). --- ### 4. Typical Applications 1. **Automotive Audio:** FM/AM car radio receivers. 2. **Home Audio:** Hi-Fi tuners and AV receivers. 3. **Communication Equipment:** Handheld transceivers and wireless data modules. ---
