Vishay BCcomponents
High Ohmic/High Voltage Metal Film Leaded Resistors
FEATURES
•
Metal film technology
•
High pulse loading (up to 10 kV) capability
•
Small size (0207/0411)
•
Compatible with lead (Pb)-free and lead containing
soldering processes
•
Compliant to RoHS directive 2002/95/EC
APPLICATIONS
•
Power supplies
A homogenous film of metal alloy is deposited 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.

MARKING
The nominal resistance and tolerance are marked on the resistor using four or five colored bands in accordance with IEC 60062,
marking codes for resistors and capacitors. 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 IEC 60115-1, category 55/155/56 (rated temperature range
- 55 °C to + 155 °C; damp heat, long term, 56 days) and along the lines of IEC 60068-2-xx test method. The tests are carried out
under standard atmospheric conditions according to IEC 60068-1, 5.3 unless otherwise specified. In some instances deviations
from IEC recommendations were necessary for our method of specifying.
