Protection for Ethernet lines
Features
■ Differential and common mode protection
■ Telcordia GR1089 Intrabuilding: 100 A, 2/10 µs
■ ITU-T K20/21: 37.5 A, 5/310 µs
■ Low capacitance: 13 pF max at 0 V
■ UL94 V0 approved resin

Benefits
■ Trisil™ technology is not subject to ageing and
provides a fail safe mode in short circuit for a
better protection.
■ This series is used to help equipment to meet
main standards such as UL61950, IEC950 /
CSA C22.2 and UL1459.

Applications
Description
This series can meet subscriber and central office
requirements.
The ETP01 series is a low capacitance transient
surge arrestor designed for protection of high
debit rate communication network. Planar
■ Protection against telecommunications surge
technology used combines a high surge capability
to comply with Telcordia GR1089 Intrabuilding
and ITU-T K20/21, and low capacitance to avoid
distortion of high speed signals such as Ethernet.
