Non-Magnetic Capacitors -
High Q, C0G/NP0, X7R - 16V to 7.2kV
MLC 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 - however, conventional
nickel barrier terminations are not suitable due to their magnetic
properties. In addition, RoHS requirement to use lead-free solders
would cause an increase in soldering temperatures and cause
solder leaching problems for the Ag/Pd termination. This has meant
alternatives have had to be found and one solution is to use a copper
barrier instead of a nickel barrier, with a tin finish on top. This non-
magnetic termination is offered with selected non-magnetic C0G/
NP0, High Q and X7R dielectrics, providing a fully non-magnetic
component (µr = 1.0000).
To meet high temperature 260ºC soldering reflow profiles as detailed
in J-STD-020, C0G/NP0 dielectrics are supplied with FlexiCap™ or
sintered termination whilst X7R dielectrics are supplied only with the
FlexiCap™ termination.
Available in chip or ribbon leaded format for certain case sizes
(consult sales office).

on request. Measurement of ESR can vary
with test method and components should only
be compared when tested back-to-back on the
same equipment under controlled conditions.
