    Abstract: The invention relates to a soft-magnetic powder comprising a core of a soft-magnetic material and a coating, the coating comprising an insulation treatment compound and an inhibitor, the inhibitor being: (e) a carboxylic acid with the general formula (I) wherein R1 is a single bond or C1-C6-alkylene. R2 to R6 are each independently H, OH, —X—COOH, C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, C3-C7-cycloalkyl, C6-C12-aryl, COOR7, OR8, or two adjacent groups R2 to R6 together form a ring, X is a single bond or C1-C6-alkylene; R7, R8 are C1-C20-alkyl; or a salt of the carboxylic acid, and/or (f) a compound of the general formula (II) (R9—O—)(R10—O—)(R11—O—)PO   (II) wherein R9 to R11 independently of each other indicate C1-C20-alkyl, C2-C20-alkenyl, C2-C6-alkynyl, C3-C7-cycloalkyl, C6-C12-aryl, unsubstituted or substituted with one or more groups selected from OH and NH2, or R9 to R11, are each independently a polydiol moiety having a molecular weight MW of 500 to 30000 g/mol which is optionally capped at the end by —C1-C20-alkyl and/or at the connection to O atom bonding to P by C1-C20-alkylene, or R10, R11 are each independently H. The invention further relates to a process for producing the soft-magnetic powder and an electronic component comprising the soft-magnetic powder.
