Cemented Wirewound Precision Resistors
FEATURES
• High power dissipation in small volume
• Ideal for pulse application
• TCR ± 100 ppm/K
• Maximum permissible hot spot temperature is
275 °C
• Lead (Pb)-free
• Tolerance 1 %
• Material categorization: For definitions of compliance
please see
www.vishay.com/doc?99912
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.
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 IEC 60 068-2-45.
