The **K15-R** typically refers to a high-voltage, ceramic disc capacitor frequently used in pulse power, X-ray equipment, and high-voltage power supplies. It is designed to handle high peak currents and high frequencies. --- ### ## Technical Specifications Below are the typical electronic characteristics of a K15-R series capacitor: | Feature | Specification | | :--- | :--- | | **Material** | Ceramic (High Permittivity) | | **Rated Voltage** | 10kV to 50kV (Standard) | | **Capacitance Range** | 100pF to 10,000pF (varies by size) | | **Dielectric Type** | Usually Y5T, Y5U, or N4700 | | **Operating Temperature** | -25°C to +85°C | | **Tolerance** | ±10% or ±20% | --- ### ### Key Electronic Components & Construction 1. **Ceramic Dielectric:** The core is a ceramic puck (often N4700 class) which provides high stability and low dissipation factors. This allows the part to withstand extreme electrical stress without breaking down. 2. **Electrodes:** Silver electrodes are fired onto the ceramic disc. These provide the conductive surface area required to store the electric charge. 3. **Encapsulation:** The part is coated in a flame-retardant epoxy resin. This protects the internal ceramic from moisture and prevents "arcing" (electrical jumping) between the leads across the surface of the component. 4. **Terminal Leads:** Heavy-duty copper or brass leads (often silver-plated) are used to ensure low resistance and high mechanical strength, as these parts are often physically large. --- ### ### Typical Applications * **Marx Generators:** Used in high-voltage pulse generation. * **X-Ray Machines:** Filtering and doubling circuits in medical or industrial imaging. * **Laser Power Supplies:** Providing the high-energy pulse required for CO2 or Excimer lasers. * **Smart Grids:** High voltage sensors and coupling devices. ---
