Power levels have been de-rated to allow for real life ‘worst case’ conditions, calculated with VSWR as 2:1
For RF applications where the connected
equipment is very sensitive to transient
overvoltages, use the higher
specification RF protectors. ESP CCTV/B
and ESP CCTV/T are suitable for use on
coaxial (or twisted pair) CCTV lines. For
coaxial CATV lines, use the CATV/F.

Technical specification
1
The maximum RF working voltage and maximum power for
the protectors is dependent on the GDT selected. See ‘Gas
Discharge Tube selection’ below.
2
The maximum transient voltage let-through of the protector
throughout the test (±10%). Response time < 10 ns. This
let-through voltage represents a deviation from the applied
signal voltage, present at the time of the test.
3
Test to IEC 61000-4-5:2006, ITU-T (formerly CCITT) K.20,
K.21 and K.45,Telcordia GR-1089-CORE, Issue 2:2002,
ANSI TIA/EIA/IS-968-A:2002 (formerly FCC Part 68).
4
The installation and connections external to the protector
may limit the capability of the protector.
