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 thickness design to meet BX require-
ments. BX dielectric code is X.
