NOVACAP
produces
capacitors
with
dielectric
characteristics COG (NPO), X7R, BX, Z5U andY5V, per EIA RS
198, as outlined in the text and graphs following. High temper-
ature versions of COG and X7R dielectrics are described in
separate data sheets for those products.
NOVACAP performs routine testing on production
representative products, for all dielectric materials, as verification of conformance to the
General Specifications. Following the guidelines of MIL-PRF-55681; periodic Group C inspec-
tions are performed on capacitor lots manufactured, with qualified materials, according to
documented procedures. The inspection data is generated following Electrical,
Mechanical and Environmental test methods and specifications of MIL-STD-202 and
EIA-198. The data records are maintained and utilized as assurance of our capa-
bility to meet the stated performance requirements.
