Thin film surface mount components
Surface mount components and related methods involve thin film circuits between first and second insulating substrates. The thin film circuits may include passive components, including resistors, capacitors, inductors, arrays of such components, networks, or filters of multiple passive components. Such thin film circuit(s) can be sandwiched between first and second insulating substrates with internal conductive pads which are exposed to the outside of the surface mount component and electrically connected to external terminations. External terminations may include at least one layer of conductive polymer. Optional shield layers may protect the surface mount components from signal interference. A cover substrate may be formed with a plurality of conductive elements that are designed to generally align with the conductive pads such that conductive element portions are exposed in groups along surfaces of a device.
