FEATURES
Overload protection without risk of fire
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 “MIL-STD-202E, method 215”, and
“IEC 60068-2-45”.
Wide range of overload currents
(refer Fusing Characteristics graphs)
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)
