Vishay BCcomponents
High Precision Leaded Resistors
FEATURES
•
High precision resistors
(TCR up to ± 5 ppm/K, 0.01 % tol.)
•
High stability (0.05 %)
•
Low temperature coefficient (up to ± 5 ppm/K)
•
Lead (Pb)-free solder contacts
•
Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
•
Compatible with “Restriction of the use of Hazardous
Substances” (RoHS) directive 2002/95/EC (issue 2004)
DESCRIPTION
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 connecting wires of electrolytic
copper are welded to the end-caps. The resistors are coated
with lacquer which provides electrical, mechanical, and
climatic protection.

12NC INFORMATION
Components may be ordered by using either a simple clear
text ordering code, see “Type Description and Ordering
Code” or Vishay BCcomponents’ unique 12NC.
•
The resistors have a 12-digit numeric code starting with
2322 14.
•
The subsequent 3 digits indicate the resistor type,
specification and packaging; see the 12NC table.
•
The remaining 3 digits indicate the resistance value. The
number is available upon request and is fixed by the
supplier.
12NC Example
The 12NC of an MPR24 resistor with tolerance of ± 0.02 %
and TCR ± 05 ppm/K, taped on bandolier in box of 100 units
starts with 2322 141 77...; the last 3 digits are available upon
request and are fixed by the supplier.

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
following specifications:
EN 140000/IEC 60115-1, Generic specification (includes
tests)
EN 140100/IEC 60115-2, Sectional specification (includes
schedule for qualification approval)
CECC 40101-806, Detail specification (includes schedule for
conformance inspection)
Most of the components are approved in accordance with the
European CECC-system, where applicable. The following
table contains only the most important tests. For the full test
schedule refer to the documents listed above. The testing
also covers most of the requirements specified by
EIA/IS-703 and JIS-C-5202.
The tests are carried out in accordance with IEC 60 068 and
under standard atmospheric conditions in accordance with
IEC 60068-1, 5.3. Climatic category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days) is
valid.
Unless otherwise specified the following values apply:
Temperature: 15
°C
to 35
°C
Relative humidity: 45 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
For testing the components are mounted on a test board in
accordance with IEC 60115-1, 4.31 unless otherwise
specified.
In the Test Procedures and Requirements table only the
tests and requirements are listed with reference to the
relevant clauses of IEC 60115-1 and IEC 60068-2; a short
description of the test procedure is also given.
