AVX has developed extreme high temperature stacked ceramic capacitors that can handle harsh and rugged operating environments.

Designated the SMX and CHX Series, the stacked ceramic capacitors were specifically designed to function in extreme temperature transitions and high transient voltage applications including down-hole oil drilling, undersea explorations, engine controls, avionics, hybrid vehicles and aerospace.

These ceramic capacitors are intended to be used with switch-mode power supplies that distribute high currents and operate within a wide voltage range and temperature range.

The SMX Series has a maximum capacitance of 340 microfarads at 25V and a maximum voltage rating of 500V.
