VTI Technologies Oy was established in 1991, and was an early pioneer in the field of MEMS devices. Continuing their strategy of acquiring companies that are leaders in their field, Murata acquired VTI Technologies Oy in January 2012. Oy is the Finnish term for company; VTI was headquartered in Vantaa, Finland. As of June 2012, the company name was changed to “Murata Electronics Oy,” but internally to Murata it is typically referred to as “MFI.” Also as of June 2012, MFI ceased using the VTI brand name and began promotion using the Murata brand name.
