Power Metal Film Leaded Resistors
DESCRIPTION
A homogeneous 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 or copper-clad iron are welded to the end-caps. The
resistors are coated with a red, non-flammable lacquer which
provides electrical, mechanical and climatic protection. This
coating is not resistant to aggressive fluxes. The
encapsulation is resistant to all cleaning solvents in
accordance with IEC 60068-2-45.
FEATURES
•High power in small packages (1 W/0207 size to
3 W/0617 size)
•Different lead materials for different applications
•Defined interruption behaviour
•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
APPLICATIONS
•All general purpose power applications
Notes
(1) 1 % tolerance is available for Rn-range from 1 R upwards
(2) Ohmic values (other than resistance range) are available on request
•R value is measured with probe distance of 24 mm ± 1 mm using 4-terminal method

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.
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).
MOUNTING
The resistors are suitable for processing on automatic
insertion equipment and cutting and bending machines.
Note
(1) Recommended minimum value
FUNCTIONAL DESCRIPTION
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the E96/E24 series for resistors with a tolerance of ± 1 % or ± 5 %.
The values of the E96/E24 series are in accordance with IEC 60063.
FUNCTIONAL PERFORMANCE
Note
• The maximum permissible hot-spot temperature is 205 °C for
PR01, 220 °C for PR02 and 250 °C for PR03

TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with
IEC 60115-1 specification, category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days).
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.
In the Test Procedures and Requirements table, 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.
All soldering tests are performed with mildly activated flux.

12NC INFORMATION FOR HISTORICAL
CODING REFERENCE
The resistors have a 12-digit numeric code starting with 23
For 5 % tolerance:
•The next 7 digits indicate the resistor type and packing
•The remaining 3 digits indicate the resistance value:
- The first 2 digits indicate the resistance value
- The last digit indicates the resistance decade
For 1 % tolerance:
•The next 6 digits indicate the resistor type and packing
•The remaining 4 digits indicate the resistance value:
- The first 3 digits indicate the resistance value
- The last digit indicates the resistance decade
Last Digit of 12NC Indicating Resistance Decade
12NC Example
The 12NC for resistor type PR02 with Cu leads and a value
of 750 Ω with 5 % tolerance, supplied on a bandolier of
1000 units in ammopack, is: 2306 198 53751.
