The part number **02011J8R2ABSTR\50** refers to a high-frequency, ultra-precision Surface Mount Device (SMD) capacitor, typically manufactured by **AVX (Kyocera-AVX)**. This specific component belongs to the **Accu-P®** series, which is designed for high-stability RF (Radio Frequency) applications. --- ### 1. Part Number Breakdown To understand the specifications, we can decode the alphanumeric string based on the AVX Accu-P standard: | Segment | Code | Meaning | | :--- | :--- | :--- | | **Size** | `0201` | Physical dimensions: 0.6mm x 0.3mm (0201 Imperial size) | | **Voltage** | `1` | Rated for **100 Volts** | | **Dielectric** | `1J` | Accu-P (Thin Film) technology for high RF performance | | **Capacitance** | `8R2` | **8.2 pF** (The 'R' acts as a decimal point) | | **Tolerance** | `A` | Tightest tolerance: **±0.05 pF** | | **Failure Rate** | `B` | Standard (Not applicable to all series) | | **Termination** | `ST` | Sn/Pb (Solder-plated) or Lead-free depending on the specific series suffix | | **Packaging** | `R\50` | Taped & Reeled (500 pieces or specific reel quantity) | --- ### 2. Key Technical Specifications Thin-film capacitors like this one differ from standard MLCCs (Multi-Layer Ceramic Capacitors) because they are manufactured using a process similar to semiconductors, ensuring extremely high precision. * **Capacitance:** 8.2 picofarads (pF). * **Voltage Rating:** 100V DC. * **Q-Factor:** Extremely high (Low loss at GHz frequencies). * **SRF (Self-Resonant Frequency):** Very high, making it suitable for circuits operating in the 2GHz to 20GHz range. * **Operating Temperature:** -55°C to +125°C. --- ### 3. Applications Due to its small size (0201) and high precision (±0.05 pF), this part is commonly found in: 1. **Mobile Communications:** Smartphones, 5G base stations, and GPS modules. 2. **RF Circuitry:** Matching networks, filters, and VCOs (Voltage Controlled Oscillators). 3. **Satellite Systems:** Low-noise amplifiers and signal processing. 4. **High-Speed Data:** Optical networking equipment. --- ### 4. Comparison: Thin Film vs. Standard MLCC Standard capacitors often have wider tolerances and higher "parasitic" effects. The **02011J8R2ABSTR** is preferred when the circuit cannot tolerate variations in capacitance. ```json { "Part_Type": "Thin Film Capacitor", "Series": "Accu-P", "Advantage": "Ultra-low ESR and High SRF", "Mounting": "SMT (Surface Mount Technology)" } ```
