ORDERING INFORMATION
All dimensions in mm
The Broadband OptimizedTM SL0902 series has been especially
developed to offer high surge ratings in a miniature package. Unique
design features offer high levels of performance on fast rising tran-
sients in the domain of 100V/s to 1kV/ss, which are those most
likely from induced lightning disturbances.
The device offers low insertion loss, so is well suited to braodband
equipment. The capacitance does not vary with voltage, so will not
cause operational problems with ADSL2+ where capacitance varia-
tion across Tip and Ring is undesirable. These devices are extreme-
ly robust and are able to divert a 2500A pulse without destruction.
For AC Power Cross of long duration, overcurrent protection is rec-
ommended.
