Thin Film on Silicon 2CTA AC Terminator x 18
General Information
Package Schematic
The AC Terminator is used to provide termination for clock
and data lines where transmission line effects would
otherwise cause wave reflections or signal ringing. These
Silicon-based, Tantalum-Nitride resistors and capacitors
feature excellent stability, temperature coefficients and
tracking performance. This product series conforms to
JEDEC standards.
