The part number **NCD682M2KVY5PD2LSTR25LSF** refers to a high-voltage ceramic disc capacitor. These components are commonly used in power supplies, lighting ballasts, and industrial equipment for filtering and decoupling. --- ### 1. Technical Specifications Breakdown The following table breaks down the parameters typically found in this specific part number: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 6.8 nF (6800 pF) | The energy storage capacity (indicated by "682"). | | **Voltage Rating** | 2000V (2kV) DC | The maximum voltage the capacitor can handle safely. | | **Tolerance** | ±20% | Indicated by "M", representing the allowed variance. | | **Dielectric Type** | Y5P | A Class II ceramic with ±10% stability over temp. | | **Operating Temp** | -30°C to +85°C | The standard range for Y5P ceramic materials. | | **Mounting Type** | Through-Hole | Radial leaded design for PCB insertion. | --- ### 2. Detailed Component Analysis #### Dielectric Characteristics (Y5P) The **Y5P** code is an EIA temperature coefficient rating: * **Y**: Minimum operating temperature of -30°C. * **5**: Maximum operating temperature of +85°C. * **P**: Maximum capacitance change of ±10% over that temperature range. * *Note:* This is considered more stable than Y5U or Y5V dielectrics. #### Physical Packaging The suffix **LSTR25LSF** usually refers to the physical configuration: * **Lead Style**: Radial leads (often "Long Straight" or specific kinked leads). * **Lead Spacing**: Often indicates a 5mm, 7.5mm, or 10mm pitch depending on the specific series. * **Tape and Reel**: Many of these suffixes denote "Tape & Reel" (TR) for automated assembly. --- ### 3. Common Applications Due to its high voltage rating and specific capacitance, this part is used in: 1. **Snubber Circuits**: Protecting transistors (MOSFETs/IGBTs) from voltage spikes. 2. **EMI/RFI Filtering**: Suppressing high-frequency noise in power lines. 3. **HV Power Supplies**: Smoothing high-voltage DC outputs. 4. **Lighting**: Electronic ballasts for fluorescent or HID lamps. --- ### 4. Safety and Alternatives When replacing or designing with this part, ensure the **Voltage (2kV)** and **Dielectric (Y5P)** are matched. Using a lower voltage or a less stable dielectric (like Y5V) can lead to component failure or circuit instability under heat.
