Procurement Notes
Verify current availability as the part status is marked obsolete. Confirm compatibility with existing thermal management solutions due to high power dissipation requirements. Ensure mounting hardware matches the flange specifications. Check for updated replacement components from the manufacturer if long-term supply stability is required for production cycles.
Selection Notes
Select this component when a robust 50-ohm termination is needed for high-power RF environments. The 1000W rating supports demanding signal loads. Consider the physical dimensions for chassis integration. Verify that the operating frequency does not exceed 1GHz. Evaluate thermal constraints given the high power handling capability.
Part Context
This resistor belongs to the CHF series, designed for high-power RF applications. It serves as a critical termination element in systems requiring stable impedance at high frequencies. The flange mount design facilitates efficient heat transfer to the chassis, ensuring reliable operation under continuous high-power conditions.
Replacement Considerations
Check for direct substitutes within the CHF series or equivalent high-power RF resistors from other manufacturers. Ensure replacement parts match the 50 Ohm resistance, 1000W power rating, and flange mounting style. Verify frequency response compatibility up to 1GHz.
