PR01/02/03 Vishay BCcomponents Power Metal Film Leaded Resistors 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 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. * 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 TECHNICAL SPECIFICATIONS VALUE PR02 DESCRIPTION PR03 PR01 Resistance 0.22 to 1 M Range (2) Resistance Tolerance and Series Cu-lead FeCu-lead Cu-lead FeCu-lead 0.33 to 1 M 1 to 1 M 0.68 to 1 M 1 to 1 M 1 % (E24, E96 series); 5 % (E24 series) (1) Rated Dissipation, P70: R<1 0.6 W 1.2 W - 1.6 W - 1R 1W 2W 1.3 W 3W 2.5 W 135 K/W 75 K/W 115 K/W 60 K/W 75 K/W Thermal Resistance (Rth) 250 ppm/K Temperature Coefficient Maximum Permissible Voltage (Umax.

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.
