Holy Stone Capacitors for Power / Adapters / Chargers / Tools

Holy Stone manufactures a broad line of multilayer ceramic capacitors specifically used in power circuits. Applicable markets include modems, Ethernet devices, DC-DC, AC-DC, switch mode (SMPS), UPS, consumer appliances, LED and lighting, ballasts/inverters/backlighting, set-top boxes/receivers, telecom equipment, automotive charging systems, cordless and AC power tools, and all power adapter and USB chargers. Available Temperature Coefficients are ultra-stable Class I COG/NPO, and Class II X7R for greater capacitance/voltage density as well as X7T and X7P dielectrics for greater 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. The Class I and Class II MLCC devices are available in sizes from 0603 up to 2225, at voltages from 100vdc to 5KVdc. Superterm® flexible termination is available upon request. This option incorporates a polymer layer in the termination structure which effectively absorbs external stresses and therefore reduces the incidence of potential product cracking. An open-mode product design is also available as a customized option – this specialized internal electrode design reduced the possibility of a short circuit due to cracking under high mechanical or thermal stress conditions. A world leader in Safety-Rated capacitors, Holy Stone also offers X1/Y2 and X2 capacitors for safety circuits.

Example applications include:

  • Surge and line protection
  • Isolation
  • EMI
  • Snubbers
  • Smoothing
  • Series and parallel busses
  • Tip-and-ring
