Power Metal Film Resistors
FEATURES
* High power in small packages * Different lead materials for different applications * Defined interruption behaviour.
APPLICATIONS
* All general purpose power applications 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, nonflammable 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 "MIL-STD-202E, method 215", and "IEC 60068-2-45".

ORDERING INFORMATION
Ordering Code (12NC) The resistors have a 12-digit ordering code starting with 23. For 5 % tolerance: * The first 9 digits indicate the resistor type and packaging. * 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 first 8 digits indicate the resistor type and packaging. * 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

MARKING
The nominal resistance and tolerance are marked on the resistor using four coloured bands in accordance with IEC publication 60062, "Colour codes for fixed resistors".
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 publication 60294").
MOUNTING
The resistors are suitable for processing on automatic insertion equipment and cutting and bending machines.
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 publication 60063".

Application Information 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. The tests are carried out in accordance with IEC publication 60068-2, "Recommended basic climatic and mechanical robustness testing procedure for electronic components" and under standard atmospheric conditions according to "IEC 60068-1", subclause 5.3. In the Test Procedures and Requirements table, 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. All soldering tests are performed with mildly activated flux.
