Abstract: The invention relates to a passive electrical component, especially a coil, having an interlayer, wherein the interlayer has a lower coefficient of thermal expansion than the surface of the passive electrical component covered with the interlayer, and disposed atop that a plasma-polymeric carbon-containing coating having a carbon content measured at a depth of 80 nm away from the side of the plasma-polymeric coating remote from the interlayer, wherein the plasma-polymeric coating comprises a carbon content of 50 to 100 atom %, preferably 50 to 90 atom %, or is configured as an organometallic coating a carbon content of 2 to 50 atom %, in each case measured by means of XPS.
