We are the preferred source of a wide range of high quality engineered ceramic powders with controlled particle size and chemistry for temperature compensating EIA Class II ultra-stable dielectric materials that exhibit minimal effects on electrical properties with temperature, frequency and time.

Our dielectric materials help MLCC manufacturers meet the demanding dielectric requirements including cost savings, higher performance, and miniaturization needs. Our Class II X7R type formulations deliver excellent dielectric reliability and compatibility with precious metal Silver(Ag), Palladium (Pd), Silver/Palladium(Ag/Pd) and base metal Nickel (Ni) inner layer conductor systems.

Capacitance for X7R varies under the influence of electrical operating conditions such as voltage and frequency. X7R dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.
