The actuator further includes a coil assembly having a coil and a fork. The fork is cantilevered from the body portion in an opposite direction from the actuator arm and includes a pair of opposed prongs to mount the coil. At least one of the prongs of the fork includes at least two opposed fins to aid in the convection of heat from the coil.
