BX DIELECTRIC
BX characteristics are identical to X7R dielectric,
with the added restriction that
the Temperature-Voltage Coefficient (TVC) is not to exceed -25%
∆C
at rated
voltage, over the operating temperature range (-55°C to 125°C). NOVACAP
manufactures chips using dielectrics with minimal voltage coefficient and layer thick-
ness designed to meet BX requirements.

Special Thickness
X in the part number denotes a special thick-
ness other than standard. Specify in mils if
required. (As shown above X=.050”)
If no X in the part number then thickness is
standard per Novacap catalog specifications.
