Technical Specifications These parts are engineered for performance where signal integrity is critical. * **Case Size:** 01005 (Extremely small: approx. 0.4mm x 0.2mm). * **Capacitance Value:** 8.2 pF. * **Working Voltage (WVDC):** 200 Volts. * **Operating Temperature:** -55°C to +125°C. * **Q-Factor:** High Q (Low loss) at microwave frequencies. * **SRF (Self-Resonant Frequency):** Typically in the multi-GHz range. --- ### 3. Key Electronic Characteristics #### A. Thin-Film Technology Unlike standard MLCCs (Multi-Layer Ceramic Capacitors) which are made via screen printing, the Accu-P series uses **photolithography**. This allows for: * Extremely tight tolerances (±0.05pF). * High repeatability (part-to-part consistency). * Lower ESR (Equivalent Series Resistance). #### B. RF Performance At high frequencies (GHz range), standard capacitors behave like inductors. The C005 series is designed to minimize parasitic inductance, making it ideal for: * Impedance matching circuits. * High-frequency filtering. * VCO (Voltage Controlled Oscillator) tuning. --- ### 4. Common Applications Due to its precision and size, this part is commonly found in: * **Mobile Communications:** 5G infrastructure and smartphones. * **Satellite TV:** LNB (Low Noise Block) downconverters. * **GPS/Navigation:** High-precision signal processing. * **Medical Electronics:** High-frequency imaging equipment.
