To determine whether the following solvents, often used to remove flux residues and other sub-
stances, are suitable for the capacitors described, refer to the table below:
Type
MKT
(uncoated)
MKT, MKP, MFP
(coated/boxed)
Even when suitable solvents are used, a reversible change of the electrical characteristics may
occur in uncoated capacitors immediately after they are washed. Thus it is always recommended
to dry the components (e.g. 4 h at 70 C) before they are subjected to subsequent electrical test-
ing.
