Part Number Breakdown The alphanumeric string defines the physical and electrical characteristics of the component: | Code Segment | Property | Meaning | | :--- | :--- | :--- | | **0402** | Case Size | 0402 (Standard Imperial: 0.04" x 0.02" / 1.0mm x 0.5mm) | | **2** | Rated Voltage | 200 Volts | | **J** | Technology | Accu-P (Thin Film) | | **8R2** | Capacitance | 8.2 pF (Picofarads) | | **A** | Tolerance | ±0.05 pF (Ultra-tight tolerance) | | **B** | Termination | Sn (Tin) over Nickel (Pb-Free / RoHS compliant) | | **S** | Temperature Coeff. | 0 ±30 ppm/°C | | **TR\500** | Packaging | Tape & Reel (Quantity: 500 pieces) | --- ### 2. Key Technical Specifications * **Technology:** Thin Film. Unlike standard multilayer ceramic capacitors (MLCCs), thin-film capacitors use high-purity materials and precise lithography, resulting in much higher accuracy and better performance at gigahertz frequencies. * **Operating Temperature:** -55°C to +125°C. * **Quality Factor (Q):** Extremely high Q-factor, which indicates very low energy loss. * **SRF (Self-Resonant Frequency):** Typically in the multi-GHz range, making it suitable for RF signal paths. --- ### 3. Common Applications Due to its high precision (±0.05 pF) and stability, this part is typically used in: 1. **RF Matching Networks:** Tuning circuits in mobile phones and base stations. 2. **Filter Circuits:** High-frequency low-pass or band-pass filters. 3. **VCOs:** Voltage Controlled Oscillators where frequency stability is paramount. 4. **Satellite Communications:** Systems requiring high reliability in the GHz spectrum. --- ### 4. Comparison: Thin Film vs. Standard MLCC | Feature | Thin Film (Accu-P) | Standard MLCC (C0G/NP0) | | :--- | :--- | :--- | | **Tolerance** | Very Tight (±0.01pF to ±0.1pF) | Standard (±5% or ±0.25pF) | | **SRF** | Very High | High | | **Stability** | Excellent over Temp/Voltage | Good | | **Cost** | Higher | Lower |
