The part number **10VF-3D0-R** typically refers to a high-voltage, surface-mount **Multilayer Ceramic Capacitor (MLCC)**, often manufactured by companies like **Walsin Technology Corp** or similar electronic component suppliers. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. General Specifications Based on standard industry nomenclature for this series, here are the technical parameters: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 10 pF (Picofarads) | | **Voltage Rating** | 3000V (3kV) DC | | **Tolerance** | ±0.5 pF (indicated by "D") | | **Dielectric Material** | NPO (C0G) - Ultra-stable | | **Package / Case** | 1206 (3216 Metric) or 1808 (varies by manufacturer) | | **Termination** | RoHS Compliant (indicated by "R") | --- ### 2. Detailed Part Number Breakdown The alphanumeric string follows a specific coding logic: * **10**: Represents the capacitance value (10pF). * **VF**: Often designates the series (High Voltage Series). * **3D0**: Represents the voltage rating. In this code, "3" is the multiplier and "D" often correlates to 3000V in specific manufacturer catalogs. * **D**: The tolerance code (±0.5 pF). * **R**: Indicates the packaging style (usually Tape & Reel) and RoHS compliance. --- ### 3. Key Technical Features * **Temperature Stability:** Since it uses the **NPO (C0G)** dielectric, the capacitance does not change significantly with temperature, frequency, or time. * **High Voltage Capability:** Specifically designed to withstand electrical stresses up to 3000V, making it suitable for power-sensitive circuits. * **Low ESR/ESL:** Provides low Equivalent Series Resistance, which is critical for high-frequency applications to prevent energy loss and heating. --- ### 4. Common Applications These components are rarely found in consumer smartphones but are essential in industrial and power electronics: 1. **Inverters and Converters:** Used for snubbing and filtering in high-voltage DC-DC converters. 2. **Lighting Ballasts:** Used in HID or LED lighting systems that require high voltage igniters. 3. **Telecom Equipment:** Employed in power supplies for networking gear to handle surge protection. 4. **Modems and Isolation:** Often used in data lines to provide isolation from high-voltage transients. ---
