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 either with powder coating or 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.

Due to the possibili ty of surface conde nsation 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 Welw yn 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, Welw yn design ers are able to provide advice and where applicable, to recommend a non- standard product. Special sizes, designs etc, can be prototyped at short notice.
