Conductor pads are printed to the rear and front faces of a 96% alumina substrate. A specially selected high voltage thick film resistor ink, based on a ruthenium oxide/glass system, is printed between the front face conductors and then covered in an overglaze before being protected with a special screen printed material which gives excellent high voltage and climatic performance. Marking Type, resistance value and tolerance are legend marked in black ink on the rear of the component. The resistance value conforms to IEC 62. Solvent Resistance The component protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuit boards Terminations Solder coated phosphor bronze leadframe terminations are solder dipped in SnAgCu and meet the following IEC requirements: IEC 68.2.21 – Strength IEC 115-1, Clause 4.17.3.2 – Solderability Packaging Packed in foam within a box. See Ordering Procedure for box quantities. Application Notes Due to the high voltage which can appear between the resistor body and any adjacent metal part, resistors should be mounted at an adequate distance from other conducting parts. Due to the possibility of surface condensation it is recommended that high voltages are not applied to resistors in areas of high humidity without the application of suitable moisture resistant lacquer Design Flexibility The experience of Welwyn engineers has been used to design this generation of high voltage planar resistors to be suitable for a majority of applications. However, should an application require particular consideration, Welwyn designers are able to provide advice and where applicable, to recommend a non- standard product. Special sizes, designs etc, can be prototyped at short notice.
