Abstract
A metallized film capacitor includes first and second winding cores disposed along a center axis, and a capacitor element wound about the center axis around the first and the second winding cores. The second winding core is apart from the first winding core. The first and second winding cores have a thermal conductivity larger than that of the dielectric film of the capacitor element. Length Lof the capacitor element in a direction of the center axis, length Lof the first winding core inside the capacitor element in the direction of the center axis, and length Lof the second winding core inside the capacitor element in the direction of the center axis satisfy the relations of L>L, L+L<L, L≧L/2, and L≧(L−L)/2. The metallized film capacitor provides the capacitor element with improved heat dissipation performance.
