Ceramic Feedthroughs

Single and multiple feedthroughs in standard dimensions and customised

Kyocera offers single terminal and multiterminal feedthroughs made of Aluminium oxide F99,7 as standard product ranges and customised components. Minimum outgassing and leakage rates, combined with excellent electrical insulation and thermal resistance levels, ensure the highest degree of reliability. The feedthroughs can be provided with corrugations to increase the creepage distance. This leads to an increased voltage level in the case of atmospheric applications. Glazing of the components facilitates both handling and cleaning procedures. The feedthroughs are routinely tested for vacuum tightness: He leakage rate: < 10^-9 mbar l/s.
