Key features and benefi ts of this 356-style protector are:  Low capacitance – Low loss on broadband applications.  Balanced protection – superior protection and improved broadband performance compared to conventional dual 2-element GDT protectors.  Switch-Grade Fail-Short device provides safer and more reliable thermal protection than solder pellet or burn through types of fail-short mechanisms. The protector element consists of Bourns’ own balanced, heavy-duty rated, 3-electrode Gas Discharge Tube (GDT). The GDT is UL Recognized to the “Gas Tube Seal Test Program”, thus eliminating a key issue of conventional GDT protectors with Air-Back-Up protection. Contamination of the BUG is historically the most common failure mode in older protector styles. Proprietary advanced technology in the GDT design helps provide exceptional energy handling and a long life. A patented Switch-Grade Fail-Short mechanism provides an extra measure of safety against thermal overload. The GDT mechanism is housed in a fi re-resistant body with binding posts for multiple wiring connections. The IDC version, with environmental sealant, provides additional ease of installation and protection against corrosion. The 2377-35-G will fi t Bourns and most manufacturers’ network interface devices and can be used universally for POTS and broadband systems such as ADSL, ADSL2+, VDSL and VDSL2. It exceeds all CAT 5 requirements. Characteristics Test Methods per IEEE C62.31, UL 497, RUS PE-80, CSA C22.2, Telcordia GR 974 and 1361.
