Description
The devices in the SMP-0SCMC series are micro
capacitance Trisils designed to protect broadband
telecommunication equipment such as DSL
modems, subscriber gateways and DSLAMs from
lightning surges and power faults.
Trisils are not subject to aging and provide a
failsafe mode in short circuit for a better
protection. They are used to help equipment to
meet main standards such as UL60950, IEC950 /
CSA C22.2and UL1459.
The SMP-0SCMC series is packaged in SMB.
