TRA25D223KGS

High temperature (+260°C) TRA series ceramic cased capacitors with a new, unique design concept are ideally suited for continuous operation up to +260°C. Problems associated with epoxy cased/epoxy potted capacitors such as material deterioration, cracks in cases and potted areas, are non-existent even at +260°C. Typical applications include oil well logging (down hole), jet engine controls and geophysical pressure probes. Conventional X7R materials lose up to 75% of the +25°C capacitance. Dissipation factor drops from 1.25% at +25°C to 0.2% at +260°C. At +120°C the ceramic undergoes a transformation (crystalline inversion) resulting in the material changing from ferroelectric to paraelectric - no piezoelectric behaviour.
