BA are bipolar 'ceramic' technology gas discharge tube intended for the protection of transmission access to telecommunications or IT equipment, against transient overvoltages due in particular to lightning. The reduced size of the BA allows its installation in volumes hitherto inaccessible to gas spark gaps. Versions for surface mounting (ref. BA CMS) or on circuit (output by wires: ref. BAS) are also available. The products are also available in 'Tape & Reel' packaging.
