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 (r = 1.0000). To meet high temperature 260C 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).
