The OHMITE 825F5R0 is a metal-housed axial lead wirewound resistor from the 89 Series. These resistors are designed for high-performance applications, offering stability during operation and secure mounting to chassis surfaces. The metal housing provides heat-sinking capabilities, allowing the units to exceed power ratings specified by MIL specifications. They meet or exceed MIL-R-18546 specifications, making them suitable for demanding industrial environments. The resistor's ceramic core and silicone internal coating contribute to its durability and performance.
