LAS-3 Carbon Comp Replacement (contact factory)
The L½S-3 is a three watt con½ormal coated precision wirewound resistor. The resistance wire is welded to the end caps and
wound on alumina rod ½or ½ood thermal conductivit½. In circuit applications that utilize two watt carbon comp resistors the L½S-3
is an idead e½½ective replacement. The L½S-3 5.6 ohm can be specificall½ desi½ned to withstand 22 jooules o½ ener½½ delivered
b½ a 1000 volt 10 x 1000 usec wave shape pulse.
