A shielded electrical cable, comprising: a plurality of conductor sets extending along a length of the cable and being spaced apart from each other along a width (w) of the cable, each conductor set including one or more insulated conductors; first and second shielding films disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched regions of the cable on each side of each conductor set; and a first adhesive layer bonding the first shielding film to the second shielding film in the pinched regions of the cable; wherein: the plurality of conductor sets comprises a first conductor set that comprises neighboring first and second insulated conductors and has corresponding first cover portions of the first and second shielding films and corresponding first pinched portions of the first and second shielding films forming a first pinched region of the cable on one side of the first conductor set, wherein the pinched portions of the first and second shielding films in the pinched regions of the cable on both sides of each conductor set are spaced apart within 0.05 mm of each other; a maximum separation between the first cover portions of the first and second shielding films is D; a minimum separation between the first pinched portions of the first and second shielding films is d1; d1/D is less than 0.25; a minimum separation between the first cover portions of the first and second shielding films in a region between the first and second insulated conductors is d2; and d2/D is greater than 0.33. a plurality of conductor sets extending along a length of the cable and being spaced apart from each other along a width (w) of the cable, each conductor set including one or more insulated conductors; first and second shielding films disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched regions of the cable on each side of each conductor set; and a first adhesive layer bonding the first shielding film to the second shielding film in the pinched regions of the cable; wherein: the plurality of conductor sets comprises a first conductor set that comprises neighboring first and second insulated conductors and has corresponding first cover portions of the first and second shielding films and corresponding first pinched portions of the first and second shielding films forming a first pinched region of the cable on one side of the first conductor set, wherein the pinched portions of the first and second shielding films in the pinched regions of the cable on both sides of each conductor set are spaced apart within 0.05 mm of each other; a maximum separation between the first cover portions of the first and second shielding films is D; a minimum separation between the first pinched portions of the first and second shielding films is d1; d1/D is less than 0.25; a minimum separation between the first cover portions of the first and second shielding films in a region between the first and second insulated conductors is d2; and d2/D is greater than 0.33. the plurality of conductor sets comprises a first conductor set that comprises neighboring first and second insulated conductors and has corresponding first cover portions of the first and second shielding films and corresponding first pinched portions of the first and second shielding films forming a first pinched region of the cable on one side of the first conductor set, wherein the pinched portions of the first and second shielding films in the pinched regions of the cable on both sides of each conductor set are spaced apart within 0.05 mm of each other; a maximum separation between the first cover portions of the first and second shielding films is D; a minimum separation between the first pinched portions of the first and second shielding films is d1; d1/D is less than 0.25; a minimum separation between the first cover portions of the first and second shielding films in a region between the first and second insulated conductors is d2; and d2/D is greater than 0.33.
