The part number **0201YK8R2ABSTR** refers to a high-frequency Thin-Film Capacitor manufactured by **AVX (Kyocera AVX)**. These components are specifically designed for RF (Radio Frequency) and microwave applications where precision and stability are critical. --- ### 1. Part Number Breakdown To understand the electronic characteristics, we can decode the part number using the standard AVX naming convention: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **0201** | Case Size | 0.6mm x 0.3mm (EIA 0201) | | **Y** | Voltage | 16 Volts | | **K** | Temperature Coeff. | 0 ± 30ppm/°C (Ultra Stable) | | **8R2** | Capacitance Value | 8.2 pF (R denotes decimal) | | **A** | Tolerance | ± 0.05 pF (Extreme Precision) | | **B** | Termination | Sn100 (Lead-Free/RoHS compliant) | | **STR** | Packaging | Tape & Reel (Standard) | --- ### 2. Technical Specifications This component belongs to the **Accu-P®** series, which uses thin-film technology rather than standard multilayer ceramic (MLCC) processes. * **Capacitance:** 8.2 pF * **Precision:** ±0.05 pF (This is a very tight tolerance, necessary for tuning circuits). * **Voltage Rating:** 16V DC. * **Operating Temperature:** -55°C to +125°C. * **Q-Factor:** Very high (Low loss at Gigahertz frequencies). * **SRF (Self Resonant Frequency):** Typically in the multi-GHz range. --- ### 3. Key Features & Applications #### Features * **High SRF:** Because it is a thin-film device, it has lower parasitic inductance than standard capacitors. * **Tight Tolerances:** Thin-film processing allows for much more accurate capacitance values than traditional ceramic firing. * **Stability:** Excellent performance over a wide range of temperatures and frequencies. #### Applications * **Mobile Communications:** Smartphones, 5G base stations, and Wi-Fi modules. * **RF Matching Networks:** Impedance matching for antennas. * **Filters:** Used in band-pass and low-pass filters for signal processing. * **Satellite TV:** LNBs (Low Noise Block downconverters). --- ### 4. Comparison: Thin-Film vs. MLCC | Feature | Thin-Film (0201YK...) | Standard MLCC | | :--- | :--- | :--- | | **Tolerance** | Very Tight (±0.05pF) | Loose (±5% or 10%) | | **Parasitics** | Ultra-low ESR/ESL | Higher | | **Frequency** | Up to 10GHz+ | Usually < 1-2GHz | | **Cost** | Higher | Lower |
