Power Metal Film Resistors

PR/2/3 Power Metal Film 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, 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-22E, method 25, and IEC 668-2-45. FEATURES High power in small packages ( W/27 size to 3 W/67 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 Compatible with Restriction of the use of Hazardous Substances (RoHS) directive 22/95/EC (issue 24) APPLICATIONS All general purpose power applications TECHNICAL SPECIFICATIONS VALUE DESCRIPTION PR2 PR3 PR Cu-lead FeCu-lead Cu-lead FeCu-lead Resistance Range (2).22 Ω tomω.33 Ω tomω Ω tomω.68 Ω tomω Ω to MΩ Resistance Tolerance and Series ± % (E24, E96 series); ± 5 % (E24 series) () Maximum Dissipation at T amb =7 C: R <Ω.6 W.2 W -.6 W - Ω R W 2W.3W 3W 2.5W Thermal Resistance (R th ) 35 K/W 75 K/W 5 K/W 6 K/W 75 K/W Temperature Coefficient ± 25 x -6 /K Maximum Permissible Voltage (DC or RMS) 35 V 5 V 75 V Basic Specifications IEC 65- and 65-4 Climatic Category (IEC 668) 55/55/56 Stability After: Load ΔR max.: ± (5 % R +.

The testing also covers the requirements specified by EIA and EIAJ. The tests are carried out in accordance with IEC publication 668-2, Recommended basic climatic and mechanical robustness testing procedure for electronic components and under standard atmospheric conditions according to IEC 668-, subclause 5.3. In the Test Procedures and Requirements table, tests and requirements are listed with reference to the relevant clauses of IEC publications 65- and 668-2 ; 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.
