VJ High Q Dielectric
Vishay Vitramon
Multilayer Ceramic Chip Capacitors
FEATURES
•
COG is an ultra-stable dielectric offering a Temperature
Coefficient of Capacitance (TCC) of 0
±
30PPM/°C over
the entire temperature range.
•
Low Dissipation Factor (DF).
•
Ideal for critical timing and tuning applications.
