LAS-3 Carbon Comp Replacement (contact factory)
The LAS-3 is a three watt conformal coated precision wirewound resistor. The resistance wire is welded to the end caps and
wound on alumina rod for good thermal conductivity. In circuit applications that utilize two watt carbon comp resistors the LAS-3
is an idead effective replacement. The LAS-3 5.6 ohm can be specifically designed to withstand 22 jooules of energy delivered
by a 1000 volt 10 x 1000 usec wave shape pulse.
LIGHTNING SURGE
Special LAS-3 5.6 ohm to 100 ohm will meet
Telecom GR-1089 lightning requirements.
