com PR01/02/03 Vishay BCcomponents Power Metal Film 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 • 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) 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”.
TECHNICAL SPECIFICATIONS VALUE DESCRIPTION Resistance range2) Resistance tolerance and series Maximum dissipation at Tamb = 70 °C: R<1Ω 1Ω≤R Thermal resistance (Rth) Temperature coefficient Maximum permissible voltage Basic specifications Climatic category (IEC 60068) Stability after: load climatic tests soldering Notes 1.
1 % tolerance is available for Rn-range from 1 R upwards.
2.
Ohmic values (other than resistance range) are available on request.
3.
R value is measured with probe distance of 24 ± 1 mm using 4- terminal method.
