ABSTRACT:
Two stacks of individual loading coils are mounted on the arms of a U-shaped bracket which is supported on a divider wall of a contoured plastic case having a pair of compartments for receiving the coil stacks. The crossarm of the bracket is shaped to fit within a correspondingly shaped notch formed in the divider wall to centrally position the stacks of coils within the compartments. In another embodiment spacer ribs project from the inner walls of the housing to provide means for accurately locating the stacks within the compartments. Encapsulating medium is introduced into the case to protect the coils and provide electrical isolation between the coil stacks.
