The part number **0201ZJ8R2ABSTR** refers to a high-precision, thin-film Surface Mount Device (SMD) capacitor manufactured by **AVX (Kyocera AVX)**. This specific component belongs to the **Accu-P®** series, which is designed for high-frequency (RF/Microwave) applications. --- ## 1. Part Number Breakdown To understand the electronic characteristics, we can decode the part number according to AVX standards: | Code | Segment | Description | | :--- | :--- | :--- | | **0201** | Case Size | 0.6mm x 0.3mm (Industry standard 0201) | | **Z** | Voltage | 10 Volts | | **J** | Temperature Coefficient | Thin Film (standard TCC) | | **8R2** | Capacitance | 8.2 pF (R denotes the decimal point) | | **A** | Tolerance | ± 0.05 pF (Ultra-tight tolerance) | | **B** | Termination | Nickel/Solder (SnPb) or Lead-Free Sn depending on series suffix | | **STR** | Packaging | Tape & Reel (Standard 7" Reel) | --- ## 2. Technical Specifications This component is specialized for circuits where signal integrity and precise capacitance are critical. * **Capacitance:** 8.2 pF * **Tolerance:** ±0.05 pF (Extremely high precision) * **Rated Voltage (WVDC):** 10V * **Dielectric Type:** Thin-Film (Silicon Dioxide/Oxynitride) * **Operating Temperature:** -55°C to +125°C * **Q-Factor:** High (Typically > 100 at 1 GHz) * **SRF (Self Resonant Frequency):** Very high, suitable for multi-GHz applications. --- ## 3. Key Electronic Characteristics ### High Precision (Thin-Film Technology) Unlike standard Multilayer Ceramic Capacitors (MLCCs) which use layers of ceramic paste, **Thin-Film** capacitors use photolithography. This allows for: * Extremely tight tolerances (±0.05 pF). * Very low ESR (Equivalent Series Resistance). * High stability over a wide frequency range. ### RF Performance The 0201 size reduces parasitic inductance, making it ideal for high-speed wireless communication. It maintains its "capacitive" behavior much higher into the GHz range than larger packages. --- ## 4. Common Applications Due to its small footprint and high precision, the **0201ZJ8R2ABSTR** is typically used in: 1. **Mobile Communications:** Smartphones, 5G base stations, and Wi-Fi modules. 2. **Impedance Matching:** Tuning RF power amplifiers. 3. **Filters:** Low-pass, high-pass, and band-pass filters in microwave circuits. 4. **VCOs:** Voltage Controlled Oscillators requiring stable frequency control.
