An electronics component operating with reflected acoustic waves having a division of weighted reflector fingers into respective sequences of sub-pieces which have a weighting offset relative to one another. A continuation of the fingers extending beyond a principal path is provided by additional, weighted sub-pieces. The additional weighted sub-pieces are at least a fundamental repetition of the sequence of sub-pieces of the corresponding weighted finger of the principal path. The additional sub-pieces are provided in view of distortions which occur causing the waves to follow a path which laterally deviates from the principal path.
