Fusible, Non-Flammable Metal Film Leaded Resistors
FEATURES
• Overload protection without risk of fire
• Wide range of overload currents
(refer Fusing Characteristics graphs)
• Lead (Pb)-free solder contacts
A homogenous 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 are welded to the end-caps. The resistors are coated
with a grey, flame retardant lacquer which provides
electrical, mechanical, and climatic protection. 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
