Huntington Electric’s high power aluminum housed resistors use centerless ground
ceramic cores for uniform heat distribution. Molded in a special high temperature materi-
al and mounted in an extruded aluminum finned housing, these designs provide maxi-
mum power dissipation and reliability. They have tinned copperweld leads for solderabili-
ty, and meet or exceed MIL-R-18546, including “N” characteristic, and MIL-R-39009.
