DESCRIPTION
BY9300 series
Plastic package, using glass passivation and a high
temperature alloyed construction.
This package is hermetically sealed and fatigue free as
coefficients of expansion of all used parts are matched.
The package should be used in an insulating medium such
as resin, oil or SF6 gas.
