High Voltage
Planar Resistors
HVP Series
Construction
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.
