Capacitor module and circuit arrangement

Abstract

The invention relates to a capacitor module (1) comprising at least four capacitors formed as coils (5), wherein the coils (5) each have an electrode (9) at their end faces (8) and a lateral surface (10) of the coils (5) is electrically insulated, wherein the capacitor module (1) comprises a first contact part (2), a second contact part (3) and a third contact part (4), wherein the first contact part (2) is for connection to a positive potential (DC+), the second contact part (3) is for connection to a negative potential (DC-) and the third contact part (4) forms a central tap (M), wherein at least one coil (5) is arranged between the first and the third contact part (4) and at least one coil (5) is arranged between the third and the second contact part (3), forming a series connection, wherein the contact parts (2-4) each have an interface contact (6) for external connections, and wherein the coils (5) are arranged in at least one row.wherein the interface contacts (6) are formed as continuous contact surfaces (7) in a longitudinal direction (L) of the capacitor module (1), wherein the contact surfaces (7) of the interface contacts (6) are parallel to each other, wherein at least two windings (5) are arranged between the first contact part (2) and the second contact part (3), wherein the windings (5) of the series connection have a first foil thickness (d1) and the windings (5) between the first and second contact part (3) have a second foil thickness (d2), wherein the second foil thickness (d2) is greater than the first foil thickness (d1) and less than twice the first foil thickness (d1).
