Telecom and Broadband Products
These product lines consist of radial leaded and
surface mount devices that protect against short
duration high voltage faults (250-600Vrms). TR
and TS products are designed to meet the protec-
tion needs of telecommunications applications.
BBR devices provide overcurrent protection of the
power tap in hybrid-coaxial applications.
TR, TS and BBR devices are not intended for
continuous utility line voltage operation
(i.e. 120v or 240V).
