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
