HAZARDOUS MATERIAL WARNING
The ceramic portion of the device between leads and metal flange is beryllium oxide. Beryllium oxide dust is highly
toxic and care must be taken during handling and mounting to avoid damage to this area.
THESE DEVICES MUST NEVER BE THROWN AWAY WITH GENERAL INDUSTRIAL OR DOMESTIC WASTE.
