Vishay BCcomponents
High Voltage Surge Metal Glaze Leaded Resistor
FEATURES
• High pulse-loading (10 kV as specified)
capability (flashes)
• Good replacement for carbon-composite
resistors
• Lead (Pb)-free solder contacts
• Pure Tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
• Compliant to RoHS directive 2002/95/EC
A metal glazed film is deposited on a high grade ceramic
body. After that caps are applied to the rods and tinned
electrolytic copper wires are welded to these end caps.
The resistors are coated with a light-blue lacquer which
provides electrical, mechanical and climatic protection.
The encapsulation is resistant to all cleaning solvents
according to IEC 60068-2-45.
APPLICATIONS
• Application in overload and high voltage pulse hazard
circuits (TV-sets, monitors), high power electronic ballasts

MARKING
MASS PER UNIT
The nominal resistance and tolerance are marked on the
resistor using colored bands in accordance with IEC 60062,
marking codes for resistors and capacitors.
MASS
(mg)
TYPE
LSR37
457
Three bands are used for 20 ꢀ tolerance with no indication
for the tolerance. Four bands are used for 10 ꢀ tolerance.
Grey is used instead of silver for 10 ꢀ because metal
particles in the lacquer could affect high-voltage properties.
OUTLINES
The length of the body (L1) is measured by inserting the
leads into holes of two identical gauge plates and moving
these plates parallel to each other until the resistor body is
clamped without deformation (IEC 60294).
FUNCTIONAL PERFORMANCE
PRODUCT CHARACTERIZATION
Standard values of rated resistance (nominal resistance) are taken from the E12 series with a tolerance of 10 ꢀ or 20 ꢀ. The
values of the E12 series are in accordance with IEC 60063.
The limiting voltage DC is not applicable, because the maximum rated voltage for the maximum Rn-value of 10 kΩ at Pn = 0.5 W
is only 70.7 V.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with
the IEC 60115-1 specifications, category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days).
In the Test Procedures and Requirements table the tests and
requirements are listed with reference to the relevant
clauses of IEC 60115-1 and IEC 60068-2-xx test methods. A
short description of the test procedure is also given. In some
instances deviations from the IEC recommendations were
necessary for our method of specifying.
The tests are carried out in accordance with IEC 60068-2-xx
test method under standard atmospheric conditions
according to IEC 60068-1, 5.3.
All soldering tests are performed with mildly activated flux.
