The **TPSKA5M50B00-R3** is a specialized electronic component manufactured by **Murata Electronics**. It belongs to the family of **Ceramic Filters**, specifically designed for intermediate frequency (IF) stage processing in communication devices. --- ## 1. Component Specifications The following table summarizes the key technical parameters of the TPSKA5M50B00-R3: | Feature | Specification | | :--- | :--- | | **Category** | Ceramic Filter (Piezoelectric) | | **Center Frequency** | 5.5 MHz | | **Bandwidth (3dB)** | 50 kHz (minimum) | | **Insertion Loss** | 6.0 dB max | | **Input/Output Impedance** | 600 $\Omega$ | | **Mounting Type** | Surface Mount (SMD) | | **Packaging** | Tape & Reel (indicated by -R3) | --- ## 2. Key Electronic Functions This part acts as a band-pass filter using the piezoelectric effect of ceramics. Its primary roles include: 1. **Frequency Selection:** It allows the 5.5 MHz signal to pass through while attenuating (blocking) unwanted noise and adjacent frequencies. 2. **Signal Shaping:** It helps define the selectivity of the receiver circuit, ensuring that the audio or data subcarrier is clean. 3. **Impedance Matching:** Designed to work within a 600-ohm circuit environment to ensure maximum power transfer and minimal signal reflection. --- ## 3. Typical Applications The 5.5 MHz frequency is standard for specific communication protocols and older television broadcasting standards. * **TV Sound IF Circuits:** Used in the sound processing stage of television receivers to isolate the audio subcarrier. * **FM Receivers:** Acting as an intermediate stage for frequency-modulated signal processing. * **Communication Equipment:** General signal conditioning in RF (Radio Frequency) transceivers. --- ## 4. Internal Structure & Materials As a **Ceramic Filter**, the device consists of: * **Piezoelectric Ceramic Element:** Converts electrical energy to mechanical vibrations and back to electrical energy at a specific resonant frequency. * **Electrodes:** Metallic layers that provide electrical contact to the ceramic. * **Substrate/Case:** A small, heat-resistant SMD package designed to withstand the reflow soldering process.
