Technical note
The high level of protection
offered by these units comes from
the addition of a high pass filter
circuit which gives a very low let-
through voltage. It should be
noted that due to this high pass
filter circuit no DC power can pass
along the transmission line. This is
referred to as “DC blocked”.
Protectors with other connectors
are available.
For RF applications where DC power is
present on the coaxial cable, use the
alternative RF protectors. The ESP
CCTV/B and ESP CCTV/T are suitable for
use on coaxial (or twisted pair) CCTV
lines. For coaxial CATV lines, use the
ESP CATV/F.

Technical specification
1
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.

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).

The installation and connectors external to the protector may
limit the capability of the protector.
