LITTELFUSE SL1003A350

Gas Discharge Tube (GDT) Products
SL1003A Series
SL1003A Series
®
Description
The SL1003A series has been especially developed
for 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 1.5pF 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, over-current protection
is recommended.
