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.
Type, resistance value and tolerance are legend marked in black ink on the rear of the component. The
resistance value conforms to IEC 62.
suitable for printed circuit boards
The component protection and marking are resistant to all normal industrial cleaning solvents
Solder coated phosphor bronze leadframe terminations are solder dipped in SnAgCu and meet the
following IEC requirements: IEC 68.2.21 – Strength, IEC 1151, Clause 4.17.3.2 – Solderability
