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
• Technology: Metal film
• AEC-Q200 qualified (PR01 and PR02)
• 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
and cleaning solvents. 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
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• All general purpose power applications
