SL1002A Series

Description

The Broadband Optimized™ SL1002A series has

been especially developed for use in broadband

equipment. Special design features provide high

levels of protection against fast rising transients

in the 100V/μs to 1kV/μs range usually caused by

lightning disturbances. These devices have ultra low

capacitance (typically 1.2pF or less) and present

insigniﬁcant signal losses up to 1.5GHz. These

devices are extremely robust and are able to divert

a 5000A pulse without destruction. For AC Power

Cross of long duration, overcurrent protection is

recommended.
