The OHMITE 89 Series Metal-Mite[®] resistors are aluminum housed axial lead wirewound resistors approved to MIL-R-18546. These resistors provide high stability during operation and allow for secure mounting to chassis surfaces. The metal housing also provides heat-sinking capabilities, allowing the units to exceed the power ratings set by MIL specifications. They are ideal for applications requiring robust performance in demanding environments, such as industrial equipment, automotive systems, and military applications.
