ABSTRACT:
Lead-less tantalum capacitors are made using a lead frame (1) formed to provide connection terminals (3,4) separated by an H-shaped aperture (7) and a bent-up anode support station (5). A two-part mould (13,13a) is used to injection mould plastics around the capacitor bodies prior to detaching the capacitors from the lead frame by severing necks (15,16,17,18).
A second embodiment has flat connection terminals which are bent around the encapsulated body.
