PAC 01..06 Series
Vishay BCcomponents
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 %
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 “MIL-STD-202E, method 215” and
“IEC 60068-2-45”.
