•
Tolerance 1 %
The resistor element is a resistive wire which is wound in a
single layer on a ceramic rod. Metal caps are pressed over
the ends of the rod. The ends of the resistance wire and the
leads are connected to the caps by welding. Tinned
copper-clad iron leads with poor heat conductivity are
employed permitting the use of relatively short leads to
obtain stable mounting without overheating the solder joint.
RoHS
COMPLIANT
The resistor is coated with a green silicon cement which is
not resistant to aggressive fluxes. The coating is
non-inflammable, will not drip even at high overloads and is
resistant to most commonly used cleaning solvents, in
accordance with “MIL-STD-202E, method 215”
and
“IEC 60068-2-45”.
