The part number **NCD682C2KVY5PE2LSTR25LSF** refers to a high-voltage ceramic disc capacitor. These components are designed to store electrical energy and filter signals in high-tension environments. --- ### 1. Technical Specifications Breakdown Based on the alphanumeric coding common to ceramic capacitors, here is the technical breakdown: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance Value** | 6800 pF (6.8nF) | Represented by "682" (68 followed by 2 zeros). | | **Voltage Rating** | 2000V (2KV) | The maximum DC voltage the dielectric can withstand. | | **Dielectric Type** | Y5P | Class II ceramic; ±10% temp stability from -30°C to +85°C. | | **Tolerance** | ±0.25pF or ±10% | Denoted by "C" or "K" suffixes depending on the manufacturer's series. | | **Mounting Type** | Through-Hole | Radial leaded configuration for PCB insertion. | | **Packaging** | Tape & Reel (STR) | "STR" usually indicates Ammo pack or Tape & Reel for automated assembly. | --- ### 2. Key Internal Components A capacitor of this type consists of three primary physical parts: 1. **Ceramic Dielectric:** A formulated ceramic disk (Titanium Dioxide or Barium Titanate) that determines the capacitance and voltage threshold. 2. **Electrodes:** Thin layers of metal (usually silver) deposited on both sides of the ceramic disk. 3. **Encapsulation:** A flame-retardant epoxy coating that protects the component from moisture and electrical arcing. --- ### 3. Common Applications Due to its high voltage rating (2KV), this part is typically used in: * **Power Supplies:** Snubber circuits to absorb voltage spikes. * **Lighting Ballasts:** High-intensity discharge (HID) or LED driver circuits. * **CRT Monitors/TVs:** Historical use in horizontal deflection circuits. * **EMI/RFI Filtering:** Suppressing high-frequency noise in line-connected equipment. --- ### 4. Safety and Handling * **Discharge:** High-voltage capacitors can retain a lethal charge even after power is removed. Always discharge them safely before handling. * **Derating:** For long-term reliability, it is recommended to operate the part at 50-60% of its rated 2KV voltage.
