      Brand History: Dale’s Legacy<\/span><\/strong>
      Founded in 1950 in Nebraska, <\/span>Dale Electronics<\/span> built a legendary reputation for manufacturing components that met the most stringent U.S. military MIL-SPEC standards. Its wound resistors are famous for withstanding extreme conditions without failure. In 1985, Dale was acquired by Vishay Intertechnology, but the name “Dale” is still imprinted and sought after by electronics purists because of its synonym for unwavering industrial durability.<\/span><\/p>\n

      (FAQ)<\/span><\/h3>\n

      Q: Does cosmetic damage to the coating affect the dissipation of the 225W?<\/span><\/strong>
      R:<\/span> No. Storage wear is purely cosmetic. As long as the internal resistive wire and connection terminals are intact (which we have verified with multimeter), the resistor will dissipate temperature according to its original factory specifications.<\/span><\/p>\n

      Q: Does this model require mounting on an aluminum heatsink?<\/span><\/strong>
      R:<\/span> It is not strictly necessary. Thanks to its generous dimensions of 260x24mm, this tubular model is designed to dissipate heat by free airflow (convection). Just be sure to leave adequate space in your cabinet for air circulation.<\/span><\/p>\n

      Q: Can I use it to test high power audio amplifiers?<\/span><\/strong>
      R:<\/span> Although electrically it will function as a dummy load, 2 ohms is a very low value (4 or 8 ohms is usually used for audio) and the wound resistors can present some inductance at high frequencies. Their ideal use is in direct current (DC) or low industrial frequencies (50\/60Hz).<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"

      Replace or design high-demanding equipment with the <\/span>Dale 2 Ohm 225W resistor<\/span><\/strong> with 5% tolerance.
