DESCRIPTION
A metal glazed film is deposited on a high grade ceramic body. After a helical groove is cut in the resistive layer, connecting
wires of electrolytic copper plated with 100 % pure tin are welded to the termination caps.
The resistors are coated with a light violet lacquer which provides electrical, mechanical and climatic protection. The
encapsulation is resistant to all cleaning solvents in accordance with “MIL-STD 202 E method 215” and “IEC 60068-2-45.”

ORDERING INFORMATION
Numeric Ordering Code (12NC)
Ordering Example
• The resistors have a 12-digit ordering code starting with
The ordering code of an SVR37 resistor value 2.7MΩ with
tolerance of ± ±1 % and supplied on a bandolier of 1000 units
in ammopack is 2322 247 82705.
2322 247.
• The subsequent first digit for 1 % tolerance products (E24
and E96 series) or 2 digits for 5 % (E24 series) indicate the
resistor type and packaging.
• The remaining digits indicate the resistance value. The first
three digits for 1 % or 2 digits for 5 % tolerance products
indicate the resistance value. The last digit indicates the
resistance in decade.

MARKING
The nominal resistance and tolerance are marked on the resistor using four or five color bands in accordance with “IEC publication
60062“ color codes for fixed resistors.
Yellow and grey colors are used instead of gold and silver because metal particles in lacquer could affect high voltage properties.
FUNCTIONAL PERFORMANCE
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the E24/E96 series for resistors with tolerance of ± 1 %, ± 5 %. The values
of the E24/E96 series are in accordance with “IEC publication 60063”

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
schedule of “IEC publication 60115-1, category LCT/UCT/56
(rated temperature range: Lower Category Temperature,
Upper category Temperature, damp heat, long term, 56
days). The testing also covers the requirements specified by
EIA and EIAJ.
and under standard atmospheric conditions according to IEC
60068-1, subclause 5.3.
In the Test Procedures and Requirements table the tests and
requirements are listed with reference to the relevant
clauses of IEC publications 60115-1 and 60068-2; 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 publication
60068-2. “Recommended basic climatic and mechanical
robustness testing procedure for electronic components”
All soldering tests are performed with mildly activated flux.
