New through-hole ceramic capacitors for high temperature applications

KEMET has introduced an expanded line of Aximax High Temperature Axial Capacitors. These new offerings are based on the same material technologies that Kemet has utilized in the surface mount X8L and X8R dielectric platforms. The new axial form factor enables these technologies to be extended into high vibration environments.

The industry’s first X8L dielectric in an axial form factor, Aximax X8L, is a conformally coated device designed to operate in environments reaching temperatures as high as 150 degrees Celsius with capacitance up to 2.2 µF and rated voltages up to 50 V.

For applications sensitive to capacitance changes such as filters, the Aximax Ultra-Stable X8R 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 degrees Celsius. These X8R devices are available with rated voltages up to 200 V.

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