for Non-

applications
C0G/NP0, High Q and X7R
Copper Barrier MLCCs
Multilayer ceramic capacitors
with silver/palladium (Ag/Pd)
terminations have often been
used in medical applications
where non-magnetic
components are required, for
example in MRI equipment.
The use of conventional nickel
barrier terminations is not
suitable due to nickel exhibiting
magnetic properties.
However, RoHS requirements
have dictated the use of
lead-free solders, and the
composition of these solders
has resulted in an increase in
soldering temperatures. This
has caused solder leaching
problems for the Ag/Pd
termination, and meant
alternative terminations have
had to be found.

Suffix
As copper is non-magnetic,
one solution is to use a copper
barrier instead of a nickel
barrier, with a tin finish on top,
and this is the solution Syfer
has developed.
This copper barrier termination
is offered with selected non-
magnetic C0G/NP0, High Q
and X7R dielectrics, providing a
fully non-magnetic component.
To meet high temperature
260ºC soldering reflow profiles
as detailed in J-STD-020, C0G/
NP0 dielectrics are supplied
with sintered termination and
X7R dielectrics are supplied
with Syfer’s award winning
FlexiCap™ termination.
