Features
A niobium capasitor is a polar capaciror.
Low profile niobium chip capacitors developed to meet growing
needs for flat capacitors where height is critical.
Small and low profile:Obtained by thinning the NMC type.

■Operating Voltage
※The voltage derating
factor should be as great
as possible.
Under normal conditions,
the operating voltage
should be reduced to
80% or less of the rated.
For ratings not covered in the table, consult Hitachi AIC.
※This catalog is designed for providing general information.
Please inquire of our Sales Department to confirm specifications prior to us.
