DESCRIPTION: TRIBALANCED PROTECTION
Dedicated protection devices for ISDN LINE
CARD and high speed data telecom lines.
Used with the recommended configuration using
3 components, they will provide =
- Dual bidirectionnal protection, with fixed
breakdown voltage in both common and
differential modes.
- Low capacitancesfrom lines to ground.
- Very good capacitance balance : ∆C= 30 pF.
