A line of high-temperature axial capacitors has been expanded, with manufacturer KEMET now offering what they claim is the industry’s first X8L dielectric in an axial form factor. Alongside the introduction of the Aximax X8L capacitor, KEMET has also made available the Aximax Ultra-Stable X8R for applications sensitive to capacitance changes such as filters.

Both devices are based on the same KEMET material technologies utilised in the surface mount X8L and X8R dielectric platforms, with the axial form factor enabling these technologies to be extended into high vibration environments.

The Aximax X8L is a conformally coated device designed to operate in environments reaching temperatures as high as 150°C with capacitance up to 2.2 µF and rated voltages up to 50 V.

The Aximax Ultra-Stable X8R, the company claim, offers superior performance and more effective capacitance when compared to competitor X8R dielectric technologies. KEMET dielectric technology exhibits no capacitance loss with respect to applied DC voltage and negligible loss of capacitance as temperatures approach 150°C. These X8R devices are available with rated voltages up to 200 V.

Both devices are lead-free, RoHS (without exemption), REACH compliant and are available in commercial and automotive (AEC-Q200) grades. Typical applications include decoupling, bypass and filtering in extreme environments such as down-hole oil exploration, under-the-hood automotive, defense and aerospace.

“KEMET is proud to offer the broadest range of high temperature solutions in the industry,” said Dr. John Bultitude, KEMET Technical Fellow. “These new Aximax products demonstrate our commitment to the development of high temperature component solutions.”
