The **SFECV10M7CQ0C01-R0** is a specific type of electronic component known as a **Ceramic Filter**, manufactured by Murata Electronics. These parts are primarily used in communication equipment for frequency selection and noise suppression. --- ### 1. General Specifications The part number encodes specific characteristics about its performance and physical build: | Feature | Specification | | :--- | :--- | | **Component Type** | Ceramic Filter (SFECV Series) | | **Center Frequency** | 10.7 MHz | | **Mounting Type** | Surface Mount Device (SMD) | | **Bandwidth (3dB)** | 110 kHz ± 30 kHz | | **Insertion Loss** | 6.0 dB max | | **Input/Output Impedance** | 330 $\Omega$ | --- ### 2. Functional Description This component belongs to the **CERALOCK®** or ceramic filter family. It is designed to allow a specific narrow band of frequencies (centered at 10.7 MHz) to pass through while significantly attenuating all other frequencies. * **10.7 MHz Standard:** This is the global standard Intermediate Frequency (IF) for **FM radio broadcasting**. * **Selectivity:** It helps the receiver distinguish between two adjacent radio stations by filtering out the "tail" of the neighboring signal. * **Piezoelectric Effect:** It functions using the mechanical vibration of a ceramic element that converts electrical energy to mechanical energy and back again, acting as a highly stable resonator. --- ### 3. Application Areas The SFECV series is commonly found in high-precision communication circuitry: * **FM Radios:** Used in the IF stage of radio tuners. * **AV Equipment:** Home theater receivers and tuners. * **Telecommunications:** Cordless phones and low-power wireless data transmission. * **Automotive:** Car audio systems (though usually, the "A" or "Q" suffix versions are preferred for automotive grade). --- ### 4. Technical Advantages * **Small Footprint:** The "V" in the series denotes a very small surface-mount package, saving PCB space compared to older leaded versions. * **Stability:** High resistance to temperature fluctuations and mechanical vibration. * **No Adjustment Needed:** Unlike LC (Inductor-Capacitor) filters, these are factory-tuned and do not require manual adjustment during assembly.
