Description

SIDACtor

Series - SMA

SIDACtor

SMA Series are designed to protect

baseband equipment such as phones, faxes, modems,

line cards, CPE and DSL from damaging overvoltage

transients.

The series provides a surface mount solution that

enables equipment to comply with global regulatory

standards.
