Summary:A feedthrough assembly includes a ferrule, an insulating structure, at least one terminal pin and a glass seal that fixedly secures the insulating structure within the ferrule. The insulating structure has a top portion, a bottom portion, and an inner diameter portion. The inner diameter portion defines at least one aperture extending from the top portion to the bottom portion of the insulating structure. The at least one terminal pin extends through the at least one aperture. The glass seal comprises about 30% B2O3, about 30% to about 40% of a member selected from the group consisting of CaO, MgO, SrO, and combinations thereof, with the proviso that the individual amounts of CaO and MgO are each not greater than about 20%, about 5% La2O3, about 10% SiO2, and about 15% Al2O3, wherein all percentages are mole percentages.
