GENERAL DESCRIPTION
AVX Corporation has supported the Automotive Industry requirements for
Multilayer Ceramic Capacitors consistently for more than 10 years. Products
have been developed and tested specifically for automotive applications and
all manufacturing facilities are QS9000 and VDA 6.4 approved.
As part of our sustained investment in capacity and state of the art
technology, we are now transitioning from the established Pd/Ag electrode
system to a Base Metal Electrode system (BME).
AVX is using AECQ200 as the qualification vehicle for this transition. A detailed
qualification package is available on request and contains results on a range
of part numbers including:
•
X7R dielectric components containing BME electrode and copper
terminations with a Ni/Sn plated overcoat.
•
X7R dielectric components, BME electrode with epoxy finish for conduc-
tive glue mounting.
•
X7R dielectric components BME electrode and soft terminations with a
Ni/Sn plated overcoat.
•
NP0 dielectric components containing Pd/Ag electrode and silver termina-
tion with a Ni/Sn plated overcoat.
