High Ohmic (upto 33 MΩ), High Voltage (upto 10 kV) Metal Film
Leaded Resistors
A homogenous film of metal alloy is depositded on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned electrolytic copper wires are
welded to the end-caps. The resistors are coated with a blue,
non-flammable lacquer, which provides electrical,
mechanical, and climatic protection.
The encapsulation is resistant to all cleaning solvents in
accordance with “MIL-STD 202E, method 215” and
“IEC 60068-2-45“.

MARKING
The nominal resistance and tolerance are marked on the resistor using four or five colored bands in accordance with IEC 60062
“Color code for fixed resistors”. Standard values of nominal resistance are taken from the E24 and E24/E96 series for resistors
with a tolerance of ± 5 % or ± 1 % respectively. The values of the E24/E96 series are in accordance with IEC 60063. Yellow and
grey are used instead of gold and silver because metal particles in the lacquer could affect high-voltage properties.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the schedule of IEC 60115-1, category 55/155/56 (rated temperature range
- 55 to + 155 °C; damp heat, long term, 56 days) and along the lines of IEC 60068-2; “Recommended basic climatic and
mechanical robustness testing procedure for electronic components” and under standard atmosphere conditions according to
