The part number **0201YK8R2ABSTR\500** refers to a high-precision surface-mount capacitor, typically manufactured by **AVX (Kyocera AVX)**. This specific component belongs to the **Accu-P®** series, which is designed for high-frequency (RF) and microwave applications where stability and low loss are critical. --- ### 1. Part Number Breakdown To understand the specifications, we can decode the alphanumeric string: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **0201** | Case Size | 0.6mm x 0.3mm (EIA 0201) | | **Y** | Rated Voltage | 16 Volts | | **K** | Temperature Coefficient | Thin Film (Low TCC) | | **8R2** | Capacitance Value | 8.2 pF (R denotes decimal) | | **A** | Capacitance Tolerance | ±0.05 pF (Ultra-Tight) | | **B** | Termination | Nickel/Tin Plated (RoHS) | | **STR** | Packaging | Tape & Reel | | **500** | Reel Quantity | 500 pieces | --- ### 2. Key Technical Specifications These parts are "Thin Film" capacitors rather than standard Multilayer Ceramic Capacitors (MLCC). This allows for much tighter tolerances and better performance at high frequencies. * **Capacitance:** 8.2 pF (Picofarads). * **Tolerance:** ±0.05 pF. This is an extremely high level of precision required for tuning RF circuits. * **Working Voltage:** 16V DC. * **Operating Temperature:** -55°C to +125°C. * **Quality Factor (Q):** High Q, meaning very low energy loss at Gigahertz frequencies. * **SRF (Self-Resonant Frequency):** Typically in the multi-GHz range. --- ### 3. Applications and Usage Due to its 0201 miniature size and high precision, this component is commonly found in: 1. **Mobile Communications:** Smartphones, 5G base stations, and WiFi modules. 2. **RF Matching Networks:** Impedance matching for antennas to ensure maximum power transfer. 3. **Satellite Receivers:** Low-noise amplifiers (LNAs) and filters. 4. **VCOs:** Voltage Controlled Oscillators where frequency stability is paramount. --- ### 4. Comparison: Thin Film vs. Standard MLCC | Feature | Thin Film (Accu-P) | Standard MLCC (C0G/NP0) | | :--- | :--- | :--- | | **Tolerance** | Extremely Tight (±0.01 to ±0.05 pF) | Standard (±0.25 pF or 5%) | | **Consistency** | High batch-to-batch stability | Variable | | **SRF** | Higher (Better for GHz) | Lower | | **Cost** | Higher | Lower |
