Features
Main applications
Any sensitive equipment requiring protection
against lightning strikes and AC power faults.
These devices are dedicated to central office
protection as they comply with the most stressfull
standards.
Their Low Capacitances make them suitable for
xDSL.
Description
The SMP100LC is a series of low capacitance
transient surge arrestors designed for the
protection of high data rate communication
equipment. Its low capacitance avoids any
distortion of the signal and is compatible with
digital transmission line cards (xDSL, ISDN...).
SMP100LC series tested and confirmed
compatible with Cooper Bussmann Telecom
Circuit Protector TCP 1.25A.
The SMP100LC-xxx with the fuse TCP1.25A or
TCP2A is compliant with Telcordia GR1089
(lightning and AC power fault tests),
ITU-T K20/K21 (lightning and AC power fault
tests), TIA/EIA-IS-968 (formely FCC Part 68
lightning tests), UL60950 (AC power fault tests).
Moreover, the use of the TCP1.25A allows the
SMP100LC-xxx to be safe for the 2nd level (B
criteria) AC power fault tests.

Benefits
Trisils are not subject to ageing and provide a fail
safe mode in short circuit for a better protection.
They are used to help equipment to meet main
standards such as UL60950, IEC950 / CSA
C22.2 and UL1459. They have UL94 V0 approved
resin. SMB package is JEDEC registered
(DO-214AA). Trisils comply with the following
standards GR-1089 Core, ITU-T-K20/K21,
VDE0433, VDE0878, IEC61000-4-5 and
FCC part 68.
