Mounting
1. Potting, sealing or adhesive compounds can produce chemical reactions in the SIOV ceramic
2. Overloading SIOVs may result in ruptured packages and expulsion of hot materials. For this rea-
Operation
1. Use SIOVs only within the specified temperature operating range.
2. Use SIOVs only within the specified voltage and current ranges.
3. Environmental conditions must not harm SIOVs. Use SIOVs only in normal atmospheric condi-
