Holy Stone produces a variety of multilayer ceramic capacitors specifically used in various lighting circuits. Temperature coefficients include stable Class I, COG/NPO dielectrics, Class II X7R for greater capacitance/voltage density as well as X7T and X7P for capacitance density and improved DC Bias characteristics. X7T and X7P dielectrics are commonly used as lower cost replacements for leaded polyester and polypropylene film capacitors. Example applications include:
- LED Drivers
- Florescent, halogen, and CFL ballast
- Industrial lighting
- Street, traffic, and safety lights
- Automotive lighting
- Snubber and smoothing
- Luminaires featuring light sensors and dimmable LED’s
Please see the schematic and reference for design examples.
