MAIN APPLICATIONS
Any sensitive equipment requiring protection
against lightning strikes and power crossing.
These devices are dedicated to central office protection as they comply with the most stressfull
standards.
Their Low Capacitances make them suitable for
ADSL.
DESCRIPTION
The SMP100LC is a series of low capacitance
transient surge arrestors designed for the protection of high debit 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.
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 GR1089 Core, ITU-T-K20/K21, VDE0433, VDE0878,
IEC61000-4-5 and FCC part 68.
