About
Oil-Cooled
1 kW RF Load Series
The 8251 Series is a high-performance line of oil-cooled RF loads for accurate, low-reflection power absorption up to 1000 watts. Self-contained and convection-cooled, they require no external power—ideal for bench testing, transmitter tuning, and non-radiating applications.
A precision film resistor immersed in dielectric coolant ensures stable 50-ohm impedance across a wide frequency range, delivering reliable, repeatable results in high-power environments.
