Syfer Technology has developed a range of high voltage capacitors in smaller packages to help product designers meet ever-tightening constraints for increased performance in a reduced form factor. The 4kV DC rated capacitors are available in the popular 1808, 1812, 2220 and 2225 case sizes, thereby delivering significant board space reductions and design flexibility, while at the same time, saving on costs.
Until now, the minimum case size required to accommodate 4kV rated capacitors has been the bulky and comparatively expensive 3640. Devices in the new range are offered in both the ultra-stable C0G (NP0) dielectric and the X7R dielectric, with capacitance values up to 5.6nF.
Available in the 1808 package, for example, are C0G devices up to 150pF and X7R capacitors up to 1nF. For higher capacitance ranges at 4kV DC, Syfer offers C0G devices up to 1.2nF and X7R dielectric components to 5.6nF in the case size 2225.
An innovative design reduces the possibility of arcing across the surface of the capacitor. The range particularly suits communications and telecoms applications, as well as industrial and military markets. Specific applications include inverters and backlighting circuits for liquid crystal displays.
