The part number **NCD682K2KVY5PC2LSTR25LSF** refers to a high-voltage ceramic disc capacitor, typically manufactured by **NIC Components** (or a similar specialty manufacturer). Below is a detailed breakdown of the electronic specifications and part number nomenclature. --- ## 1. Technical Specifications Table | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Ceramic Disc Capacitor | Fixed value, non-polarized capacitor. | | **Capacitance** | 6800 pF (6.8 nF) | "682" code: 68 followed by 2 zeros. | | **Tolerance** | ±10% | Indicated by the "K" character. | | **Voltage Rating** | 2000V (2KV) | Designed for high-voltage suppression or coupling. | | **Dielectric Type** | Y5P | Class II ceramic; stable temperature coefficient (±10% drift). | | **Lead Spacing** | 2.5mm / 5.0mm | Specific lead pitch for PCB mounting. | | **Packaging** | Tape & Reel / Ammo | Indicated by "TR" suffix. | --- ## 2. Part Number Breakdown To understand the specific characteristics, we can deconstruct the code: ### **A. Capacitance Code: 682** * **68**: The significant figures. * **2**: The multiplier (10 to the power of 2). * **Result**: 6800 picofarads (pF), which equals **6.8nF** or **0.0068µF**. ### **B. Tolerance Code: K** * **K** stands for **±10%**. This is standard for bypass and decoupling applications where exact precision is less critical than the ability to handle high voltage. ### **C. Voltage Rating: 2KV** * This capacitor is rated for **2000 Volts DC**. It is built with thicker ceramic layers to prevent dielectric breakdown at high electrical potential. ### **D. Dielectric Characteristic: Y5P** * **Y**: Minimum temperature of -30°C. * **5**: Maximum temperature of +85°C. * **P**: Maximum capacitance change of **±10%** over that temperature range. * *Note: Y5P is considered a "stable" Class II dielectric compared to Y5V or Z5U.* --- ## 3. Typical Applications Because of its high voltage rating and specific capacitance, this part is commonly used in: * **Switch Mode Power Supplies (SMPS):** Snubber circuits to protect MOSFETs from voltage spikes. * **Lighting Ballasts:** Filtering and ignition circuits in HID or fluorescent lighting. * **CRT/Displays:** High voltage coupling in older monitor technology. * **DC-DC Converters:** Input/output noise filtering in industrial equipment. --- ## 4. Mechanical & Packaging Codes * **LS (Lead Spacing):** Defines the distance between the two wires. * **TR (Tape & Reel):** Prepared for automated pick-and-place assembly machines. * **F:** Usually indicates **RoHS Compliance** (Lead-Free).
