The part number **NCD682C2KVY5PD2LSTR25LSF** corresponds to a high-voltage, leaded ceramic disc capacitor. Below is a detailed breakdown of its specifications and electrical characteristics. ### 1. Part Number Deciphering Based on standard industry nomenclature for ceramic disc capacitors (common for manufacturers like NIC Components or similar): | Segment | Meaning | Specification | | :--- | :--- | :--- | | **NCD** | Series | Ceramic Disc Capacitor | | **682** | Capacitance Code | 6,800 pF (6.8 nF) | | **C** | Tolerance | ±0.25pF or Standard Code (context dependent) | | **2KV** | Voltage Rating | 2,000 Volts DC (2kV) | | **Y5P** | Temp. Coefficient | ±10% variation from -30°C to +85°C | | **D2L** | Physical Size | Lead spacing/Disc diameter code | | **TR/25** | Packaging | Tape and Reel / 25mm Pitch | --- ### 2. Technical Specifications #### Electrical Properties * **Capacitance:** 6.8 nF (nanofarads). This is a mid-range value typically used for filtering or decoupling. * **Voltage Rating:** 2kV (2000V). This indicates it is a **High Voltage** component, suitable for power supplies and CRT circuits. * **Dielectric (Y5P):** This is a Class II ceramic material. It offers high volumetric efficiency (small size for the capacitance) but is less stable over temperature than Class I (C0G/NP0) materials. #### Physical Attributes * **Mounting Type:** Through-hole (Leaded). * **Form Factor:** Disc-shaped with radial leads. * **Packaging:** Tape and Reel (TR), designed for automated insertion machines. --- ### 3. Common Applications Due to the high voltage rating and the specific dielectric properties, this part is typically found in: 1. **Snubber Circuits:** Used to suppress voltage spikes in switching power supplies. 2. **High-Voltage Coupling:** Blocking DC while allowing AC signals to pass in high-voltage stages. 3. **Lighting Ballasts:** Used in fluorescent or HID lighting controllers. 4. **Bypass/Filtering:** Filtering high-frequency noise in lines carrying up to 2000V. --- ### 4. Safety and Handling * **Voltage Derating:** It is best practice to run these capacitors at 50-60% of their rated voltage (approx. 1kV to 1.2kV) for long-term reliability. * **Discharge:** Because it can hold 2000V, ensure the capacitor is fully discharged before handling a board to prevent electrical shock.
