Vishay Vitramon
Document Number 45050
Revision 06-Apr-01
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.
Multilayer Ceramic Chip Capacitors
