The **MA13FBA-R** is a specific electronic component, typically identified as a **high-precision, high-frequency Thin Film Chip Inductor** (often associated with manufacturers like Susumu or similar precision component specialists). These parts are critical in high-frequency RF (Radio Frequency) applications where stability and low loss are paramount. --- ### 1. Key Technical Specifications Below are the typical parameters for this series of components: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Thin Film Chip Inductor | | **Case Size** | 0603 (Metric 1608) | | **Inductance Range** | Low nH range (e.g., 1.3nH - 100nH) | | **Tolerance** | ±0.1nH or ±2% (High Precision) | | **Operating Temperature** | -55°C to +125°C | | **Mounting Type** | Surface Mount (SMD/SMT) | --- ### 2. Functional Characteristics * **Thin Film Technology:** Unlike wire-wound inductors, these use photo-lithography on ceramic substrates. This allows for extremely tight tolerances and high reproducibility in mass production. * **High Self-Resonant Frequency (SRF):** Due to the precise construction, these parts can operate at very high frequencies (GHz range) without becoming capacitive. * **High Q-Factor:** They offer low DC resistance (DCR), which results in high efficiency and minimal signal loss in RF circuits. --- ### 3. Application Areas The MA13FBA-R is designed for circuitry where signal integrity is the highest priority: 1. **Mobile Communications:** Used in smartphones and base stations for power amplifier matching. 2. **RF Modules:** Essential for Bluetooth, Wi-Fi, and GPS front-end modules. 3. **VCOs:** Used in Voltage Controlled Oscillators to stabilize frequency. 4. **Impedance Matching:** Crucial for matching the antenna to the transceiver to prevent signal reflection. --- ### 4. Part Number Breakdown (General Pattern) While coding varies by manufacturer, the suffix and prefix usually denote: * **MA:** Series identifier (Thin film RF). * **13:** Physical size or base inductance value. * **F:** Tolerance code (e.g., ±1%). * **BA:** Material or specialized characteristic code. * **-R:** Packaging code (usually signifies "Tape and Reel"). ---
