HT13 150C Dielectric Development

• New high temperature capacitor dielectric • Accelerated life testing complete at 2,000 hours

and 150C• Outstanding peak current performance • Stable capacitance over temp range from -6% to

+4% from -55C to +150C• Low loss - DF decreases with increasing temp

(0.10% at 1kHz and 150C)• October product introduction – snubber capacitors
