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 nonmagnetic 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).
