The part number **NCD682Z2KVY5PC2LSTR25LSF** refers to a high-voltage ceramic disc capacitor. These components are designed to store charge and filter signals in circuits where high voltage stability is required. ### Part Number Breakdown Based on standard industry naming conventions for ceramic capacitors (likely manufactured by companies like NIC Components or similar specialized suppliers), here is the technical breakdown: | Specification | Detail | Explanation | | :--- | :--- | :--- | | **Capacitance Value** | **682** | 6800 pF (6.8 nF). The '2' is the multiplier ($10^2$). | | **Tolerance** | **Z** | +80% / -20%. This is common for decoupling capacitors. | | **Voltage Rating** | **2KV** | 2,000 Volts DC. High voltage capability. | | **Dielectric Type** | **Y5P** | Class II dielectric. Stable within ±10% from -30°C to +85°C. | | **Lead Style** | **LSTR** | Long Straight Leads (often refers to Taped/Reeled packaging). | | **Lead Spacing** | **25LS** | 2.5mm or 0.25-inch Lead Spacing. | | **Finish/Special** | **F** | RoHS Compliant / Lead-Free. | --- ### Technical Specifications #### 1. Capacitance & Dielectric * **Value:** 6.8nF is a mid-range value typically used for EMI suppression or transient voltage snubbing. * **Y5P Material:** This is a "Stable" Class II ceramic. It offers a higher volumetric efficiency than Class I (C0G) but has more sensitivity to temperature and voltage changes than Class I. #### 2. High Voltage Performance * The **2000V (2KV)** rating makes this part suitable for power supplies, CRT displays, and lighting ballasts. It is built with a thicker ceramic layer to prevent internal arcing under high electrical stress. #### 3. Physical Construction * **Type:** Disc Ceramic. The capacitor consists of a ceramic disc coated with silver on both sides, with tinned copper leads soldered to the surfaces. * **Coating:** Usually encapsulated in a flame-retardant epoxy resin (UL94V-0). --- ### Common Applications * **Snubber Circuits:** Used in switching power supplies to absorb high-voltage spikes generated by transformers. * **DC Blocking:** Used in high-voltage lines to block DC while allowing AC signals to pass. * **Filtering:** Reducing electrical noise in motor controllers or high-voltage DC-DC converters. * **Lighting:** Used in electronic ballasts for fluorescent or HID lamps. --- ### Typical Circuit Symbol In a schematic, this part is represented by two parallel lines: ```text | | ------| |------ | | 6.8nF 2KV ```
