A bearing system for a turbocharger shaft includes two angular contact ball bearings mounted in the opposite ends of a lubricated rotatable elongated cylinder, which includes a radially extending flange at one end that cooperates with stationary housing portions and carries the thrust load of the rotor in both directions. Each of the feedthrough filtered capacitors has a distinct first set of electrode plates, a non-distinct second set of electrode plates, and a first passageway through which a respective terminal pin extends in conductive relation with the first set of electrode plates. The tubular sleeve is movable relative to the rupture crown between a first position in which the rupture crown resides within the tubular sleeve and a second position in which the rupture crown extends from the tubular sleeve.
