A range of X7R MLC capacitors with a guaranteed nonmagnetic / relative permeability of 1.000 and having a customized design to achieve a lower ESR and improved Q factor than normal X7R MLCC’s. Ideal for critical applications such as NMR / MRI and where PIM could potentially be an issue if nickel was present. These MLCC's can be used where an improved performance is required, such as blocking caps.
