OHMITE 80 Series Wirewound Resistors
Ohmite 80 Series Wirewound Resistors are commercial grade Acrasil‚ silicone-ceramic conformal axial wirewound resistors. These high-quality resistors are characterized by their low-temperature coefficient and maintain high stability under demanding conditions. The 80 series wirewound resistors are high voltage, high power resistors with a 25°C to 275°C operating temperatures range. These all-welded units come with 1% and 5% tolerances and the resistors from the RW series meet the requirements of MIL-R-26. The 80 series silicone-ceramic wirewound resistors are ideally used in a wide range of precision power applications, including industrial, commercial, and military equipment.
