250 Series ‘Thin’ Stackohm® Vitreous Enamel Power When limited space is a consideration, choose Ohmite’s “thin” stackable 250 Type resistors. These oval-shaped ceramic-core resistors feature a low profile to permit installation in spaces with height restrictions. They are also equipped with integral mounting brackets so they can be fastened to a chassis and stacked in locations with limited surface area. When properly fastened, the mounting brackets add a heat sinking benefit resulting in a smaller size per watt. Durable 250 Type resistors are fully welded and coated with lead free vitreous enamel. F e at u r e s • Small size-to-power ratio. • Stackable • Integral mounting bracket conducts heat to mounting surface. • Low profile for use in equipment where space is limited. • All-welded construction. • RoHS compliant product available. Add “E” suffix to part number to specify. S ERIE S S P ECI F ICATI O N S Series F10 F20 F30 F40 F55 Wattage 10 20 30 40 55 Ohms 1.0-15K 1.0-50K 1.0-10K 1.0-25K 1.0-30K Max.

Approximate ratings are given in the table. Percent of Single Unit Rating In addition to the standard box bracket, stud type brackets are available for stacking the standard size resistors. Stud type brackets are available in two heights: standard (SS, 0.437”/11.113mm) and high (SSH, 0.531”/13.494mm). The SSH stud is recommended when stacking the adjustable Type 260, as it assures clearance for the adjustable lugs to pass eachother. Spacer washer No. 6027 (O.D. 0.219”/5.556mm, I.D. 0.125”/3.175mm, thickness 0.094”/2.381mm) is recommended for use with the miniature adjustable and fixed resistors to provide clearance, as explained above, or increased wattage.
