## CDACV10M7GA001-R0: Electronic Component Overview The **CDACV10M7GA001-R0** is a specialized ceramic discriminator manufactured by **Murata Manufacturing Co., Ltd.** It is primarily used in communication equipment for demodulating FM (Frequency Modulation) signals. --- ### 1. Technical Specifications This component belongs to the ceramic filter/discriminator family, specifically designed for 10.7 MHz intermediate frequency (IF) applications. | Feature | Specification | | :--- | :--- | | **Center Frequency (fo)** | 10.700 MHz | | **Bandwidth (at 3dB)** | ±150 kHz min. (varies by IC) | | **Recovered Audio Voltage** | 650 mV min. | | **Distortion Factor** | 1.0% max. | | **Operating Temperature** | -20°C to +80°C | | **Package Type** | Surface Mount Device (SMD) | --- ### 2. Functional Principles A ceramic discriminator acts as a frequency-to-voltage converter. In an FM receiver circuit, it works alongside an FM IF IC to convert the frequency variations of the incoming signal into an audible voltage (audio signal). #### Key Characteristics: * **Piezoelectric Effect:** Utilizes the mechanical resonance of piezoelectric ceramics. * **IC Compatibility:** This specific model is often matched with specific FM receiver ICs (such as the Toshiba TA series or Sanyo LA series) to ensure linear demodulation. * **Adjustment-Free:** Unlike traditional LC (Inductor-Capacitor) coils, ceramic discriminators do not require manual tuning during production, which simplifies the assembly process. --- ### 3. Physical Dimensions & Part Number Breakdown The "CDACV" series is known for its small footprint, making it ideal for portable electronics. * **CDA**: Ceramic Discriminator. * **CV**: Small SMD package style. * **10M7**: Frequency (10.7 MHz). * **GA001**: Design code related to bandwidth and IC matching characteristics. * **R0**: Packaging code (typically refers to Tape & Reel). --- ### 4.
