The part number **NCD682Z2KVY5PJ2LSTR25LSF** corresponds to a specific high-voltage ceramic disc capacitor. Below is a detailed breakdown of its technical characteristics and internal electronic structure. --- ### 1. Technical Specification Table | Parameter | Value / Description | | :--- | :--- | | **Capacitance** | 6800 pF (6.8 nF) | | **Tolerance** | +80%, -20% (Z Code) | | **Voltage Rating** | 2000V (2kV) DC | | **Dielectric Material** | Y5P (Class II Ceramic) | | **Mounting Type** | Through-Hole (Radial Leads) | | **Lead Spacing** | 2.5mm or 5.0mm (standard variant dependent) | | **Termination** | Long Straight Leads / Tape & Reel (STR) | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific manufacturer nomenclature (likely NIC Components or similar): * **NCD**: Series prefix for Ceramic Disc Capacitors. * **682**: Capacitance value. The first two digits (68) are the significant figures, and the third (2) is the multiplier ($10^2$). Result: $6800$ pF. * **Z**: Tolerance code ($+80\% / -20\%$). Common for decoupling applications where precision is less critical than bulk capacitance. * **2KV**: Voltage rating indicating the component can handle up to 2000 Volts. * **Y5P**: Temperature coefficient. * **Y**: Minimum temp $-30^\circ\text{C}$ * **5**: Maximum temp $+85^\circ\text{C}$ * **P**: Max capacitance change of $\pm10\%$ over that range. * **LS / TR**: Lead Style and Packaging (Tape and Reel). --- ### 3. Electronic Functionality This part is engineered for high-stress environments. Key electronic behaviors include: 1. **High Dielectric Strength:** The ceramic material is processed to prevent arcing and internal breakdown at high potential differences (2kV). 2. **Bypass & Decoupling:** In high-voltage circuits, it provides a low-impedance path to ground for high-frequency noise, protecting sensitive components. 3. **Snubber Circuits:** Often used to absorb "inductive kickback" or voltage spikes in power supplies and CRT displays. 4. **Frequency Response:** As a Class II ceramic, it offers high volumetric efficiency but may exhibit non-linear capacitance changes with voltage and frequency. --- ### 4. Common Applications * **Switch Mode Power Supplies (SMPS):** Used on the primary side for noise suppression. * **Lighting Ballasts:** Handling the high start-up voltages of HID or Fluorescent lamps. * **DC-DC Converters:** Filtering high-voltage rails. * **Surge Protection:** Acting as a primary line of defense against transient voltage spikes.
