The part number **NCD682C2KVY5PC2LSTR25LSF** refers to a high-voltage ceramic disc capacitor. These components are commonly used for decoupling, bypass, and snubbing applications in high-voltage power supplies and lighting ballasts. --- ### Technical Specifications Breakdown | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 6800 pF (6.8nF) | The amount of charge the capacitor can store. | | **Capacitance Code** | 682 | 68 followed by 2 zeros (6800). | | **Voltage Rating** | 2000V (2kV) | Maximum DC voltage the part can handle safely. | | **Dielectric Type** | Y5P | Temperature coefficient (±10% change from -30°C to +85°C). | | **Tolerance** | C (±0.25pF) / K (±10%) | Usually ±10% for this capacitance range. | | **Mounting Type** | Through-Hole | Radial leaded design. | | **Packaging** | Tape & Reel (TR) | Supplied on a reel for automated assembly. | --- ### Key Component Features 1. **High Voltage Stability:** Designed to operate at 2kV, making it suitable for AC line filtering and protecting circuits against voltage surges. 2. **Y5P Dielectric:** This is a Class II ceramic material. It offers high volumetric efficiency (more capacitance in a smaller size) but has a moderate non-linear temperature sensitivity compared to C0G/NP0 materials. 3. **Construction:** Ceramic disc capacitors consist of a ceramic wafer with metallic electrodes deposited on both sides. The entire assembly is encapsulated in a flame-retardant epoxy resin. ### Common Applications * **Switch Mode Power Supplies (SMPS):** Used in the primary side for snubbing high-frequency noise. * **Lighting Ballasts:** Found in LED drivers and HID lighting systems. * **EMI/RFI Filtering:** Suppressing electromagnetic interference in high-voltage lines. * **DC-DC Converters:** Providing decoupling for high-voltage rails. ### Schematic Representation ```text C1 ----||---- 6.8nF 2000V ``` ---
