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. Special LAS-3 5.6 ohm to 100 ohm will meet Telecom GR-1089 lightning requirements. • V = 1000 volts • T1 = 10 usec rise • T2 = 1000 usec to V2 • 10 ohm output impedance MICROSECONDS T2 LIGHTNING SURGE T1 0 V2 V |
