The present invention pertains to a hard disk drive form factor compatible solid-state storage device enclosure assembly that protects circuit boards contained within the enclosure from environmental disruption, such as mechanical stress, vibration, external electronic disruption, or any combination of these, while allowing for a variable number of circuit boards in the SSD enclosure. In another embodiment, the solid-state storage device enclosure assembly, or a similar circuit board assembly, includes an alignment guide that precludes a circuit board from being misaligned within the enclosure.

An EMC filter device for power electronics of an electric machine includes an electric conductor structure, a capacitor coupled to the conductor structure, and an inductor that cooperates with the conductor structure. The conductor structure has at least two separate conducting layers that are insulated from one another.
