Abstract
Abstract A chip component incorporating an electrical or electronic function member (2) and having terminal elements (7, 8) is integrated in a pre-fabricated housing (9) of cup shape composed of insulating material, with the function member (2) being held in the housing (9) by supporting elements (12) so as to form at least one air gap (10) that is 1 mm less wide and that separates the function member (2) from the inner housing surfaces (11) on all sides except where the function member (2) is fixed in the housing (9) with small-area supporting elements (12).
