BX Series

Description Features Applications Datasheet PDF file Application Notes Technical Support Request for Quotation Sample Request

The BX series of miniature two electrode spark gaps (2.0-20.0kV) has been designed for applications that have severe environment and high reliability requirements. These gaps are made with high alumina ( Al₂O₃ ) ceramic cylinders and metal electrodes that are hermetically sealed at high braze temperatures to withstand extreme levels of temperature and rugged environmental conditions. The small size of the BX gaps allows alternative
mounting methods, including circuit board mounting, as well as external clamping of the ceramic envelope by using low dielectric materials.
