The part number **02011J8R2ABSTR\500** refers to a high-precision, thin-film Surface Mount Device (SMD) capacitor, typically manufactured by **Kyocera AVX**. These components are specifically designed for high-frequency applications, such as RF (Radio Frequency) circuits, due to their tight tolerances and stable performance. ### 1. Part Number Breakdown The alphanumeric string defines the specific electrical and physical characteristics of the component: | Code Segment | Meaning | Detail | | :--- | :--- | :--- | | **0201** | Case Size | 0.02" x 0.01" (0.6mm x 0.3mm) - Extremely small. | | **1** | Voltage | Rated for **100 Volts**. | | **J** | Technology | **Accu-P®** (Thin Film technology). | | **8R2** | Capacitance Value | **8.2 pF** (The 'R' acts as a decimal point). | | **A** | Tolerance | **± 0.05 pF** (Ultra-tight tolerance). | | **B** | Termination | Sn (Tin) over Ni (Nickel) plating. | | **S** | Temperature Coeff. | 0 ± 30 ppm/°C (Highly stable). | | **TR\500** | Packaging | Tape & Reel, quantity 500 units. | --- ### 2. Technical Specifications This part belongs to the **Accu-P® series**, which is known for its high Q-factor and low ESR (Equivalent Series Resistance). * **Capacitance:** 8.2 pF * **Tolerance:** ± 0.05 pF (Standard for precision RF tuning) * **Rated Voltage:** 100V DC * **Operating Temperature:** -55°C to +125°C * **Mounting Type:** Surface Mount (SMT) * **Technology:** Thin Film (Provides better consistency than standard multilayer ceramic capacitors/MLCCs). --- ### 3. Key Applications Because of its small size (0201) and high frequency stability, this part is used in: * **Mobile Communications:** Smartphones, 5G base stations. * **Satellite TV Receivers:** LNB (Low Noise Block) downconverters. * **RF Power Amplifiers:** Impedance matching and coupling. * **VCOs:** Voltage Controlled Oscillators. * **GPS/Navigation:** High-accuracy signal processing. --- ### 4. Handling Precautions The **0201 case size** is roughly the size of a grain of salt. * **Soldering:** Requires precision automated pick-and-place machines and reflow soldering. Manual soldering is extremely difficult and not recommended. * **Moisture Sensitivity:** Typically rated MSL 1 (no special storage needed), but should be kept in original packaging to prevent oxidation of the terminals.
