The part number **0201YJ8R2ABSTR** refers to a high-precision **Thin Film Chip Capacitor** manufactured by **Kyocera AVX**. These components are specifically designed for high-frequency (RF/Microwave) applications where stability and low loss are critical. --- ### 1. Part Number Breakdown Understanding the alphanumeric code reveals the specific electrical characteristics of the component: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **0201** | Case Size | 0.6mm x 0.3mm (EIA 0201) | | **Y** | Voltage | 16 Volts | | **J** | Technology | Accu-P® (Thin Film) | | **8R2** | Capacitance | 8.2 pF (R denotes decimal) | | **A** | Tolerance | ±0.05 pF (Ultra-tight) | | **B** | Termination | Sn100 (Lead-Free / RoHS) | | **STR** | Packaging | Tape & Reel | --- ### 2. Technical Specifications This part belongs to the **Accu-P®** series, which uses thin-film deposition technology rather than standard multilayer ceramic (MLCC) processes to ensure high accuracy. * **Capacitance:** 8.2 pF * **Tolerance:** ±0.05 pF (extremely precise for RF tuning) * **Rated Voltage:** 16V DC * **Operating Temperature:** -55°C to +125°C * **Q-Factor:** Very high (Low ESR/ESL at GHz frequencies) * **Temperature Coefficient:** 0 ± 30 ppm/°C (highly stable across temperature changes) --- ### 3. Key Applications Because of its small footprint (0201) and high precision, this part is commonly used in: 1. **Mobile Communications:** Smartphones, 5G base stations, and IoT devices. 2. **RF Matching Networks:** Impedance matching for antennas to minimize signal reflection. 3. **VCOs:** Voltage Controlled Oscillators requiring tight frequency control. 4. **Filters:** Low-pass, high-pass, and band-pass filters in wireless circuits. --- ### 4. Handling and Soldering Due to the **0201 size**, this component requires specialized automated assembly: * **Placement:** High-precision SMT (Surface Mount Technology) pick-and-place machines. * **Soldering:** Reflow soldering is recommended. Manual soldering is extremely difficult and can result in "tombstoning" (the part standing up on one end) due to unbalanced surface tension.
