Surface-mountable device element i.e. surface mountable device temperature gauge, for heating coupling section of e.g. flow controller, has side with contact point electrically isolated by another side for contacting device element

摘要

The element has a side (17), which has a metallic surface (16), and another side (11), which has a contact point (7, 8) electrically isolated by the side (17) for contacting the element. The contact point and/or the metallic surface is formed in a solderable manner. An electrical component is electrical conductively connected with the contact point. The electrical component has an electrical resistor, whose resistance changes depending on a temperature of a coupling section (1) that has a barrier layer below a solderable coating of the element. The resistor has platinum or a platinum alloy.
