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.

Features

• RoHS compliant

• Low insertion loss

• Surface mountable

• 5kA surge capability
tested with 8/20/μs
pulse as defined by IEC
61000-4-5

• GHz working frequency

• Can be used to meet
Telcordia GR1089
without series
resistance

• 10/700 6kV capability,
as per ITU-Tk.21,
enhanced test level

• 2000 Amp 2/10μs surge
rating

• Excellent response to
fast rising transients

Applications

• Broadband equipment

• ADSL equipment

• XDSL equipment

• Satellite and CATV
equipment

• General telecom
equipment
