CSA70

CSA70 is a chip type surge absorber for protecting communication networks.
Through our long history of developing microgap products, we have been able to realize a product with excellent surge protection characteristics and low capacitance of less than 0.6pF. Even with its small package design, it is easily able to withstand 1,500A (8/20μsec.) surges. Meets the standard for ADSL POTS* splitters, in accordance with ITU-T (International Telecommunication Union test standard) K.20 and K.21 Basic Test Conditions.
*POTS : Plain Old Telephone Service

Features

• Standard small chip package (EIA 1612, height 2.3+/-0.2mm), for use with standard place and reflow solder equipment.

• Superior surge response characteristics from microgap technology.

• Low capacitance of less than 0.6pF means no appreciable attenuation on high-speed, megabit class communication signals.

• High insulation resistance of over 100Mohm.

• Use tin plated electrodes and are completely lead free.
