The part number **02011J8R2ABSTR\500** refers to a high-precision Thin Film Surface Mount Capacitor, typically manufactured by **AVX (Kyocera AVX)**. This component is part of the **Accu-P®** series, which is designed for high-frequency (RF/Microwave) applications where stability and low loss are critical. --- ### 1. Part Number Breakdown Understanding the alphanumeric code reveals the specific electrical characteristics: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **0201** | Case Size | 0.02 x 0.01 inches (0.6 x 0.3 mm) | | **1** | Voltage Rating | 100 Volts | | **J** | Temperature Coeff. | 0 ± 30 ppm/°C (Ultra-stable) | | **8R2** | Capacitance Value | 8.2 pF (Picofarads) | | **A** | Capacitance Tolerance | ± 0.05 pF (Ultra-tight tolerance) | | **B** | Termination | Sn100 (Lead-Free/RoHS compliant) | | **STR** | Packaging | Taped and Reeled | | **\500** | Quantity | 500 pieces per reel | --- ### 2. Technical Specifications This component is engineered for precision rather than bulk energy storage. * **Technology:** Thin Film (allows for tighter tolerances and higher stability compared to standard MLCCs). * **Operating Temperature:** -55°C to +125°C. * **Quality Factor (Q):** Very high Q at microwave frequencies (low energy loss). * **Self-Resonant Frequency (SRF):** Typically in the multi-GHz range, making it ideal for high-speed signals. --- ### 3. Key Applications Because of its tiny **0201** footprint and **±0.05 pF** tolerance, it is used in: 1. **RF Matching Networks:** Tuning antennas in smartphones and wearable devices. 2. **Filter Circuits:** Used in band-pass or low-pass filters for 5G, Wi-Fi, and Bluetooth modules. 3. **VCOs:** Voltage Controlled Oscillators requiring precise frequency stability. 4. **Satellite Communications:** High-frequency signal processing. --- ### 4. Handling & Soldering * **Size Warning:** 0201 components are extremely small (resembling a speck of dust). They require automated Pick-and-Place machinery and high-precision stencil printing. * **Soldering:** Compatible with standard reflow soldering profiles (Lead-free).
