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
