Published ratings and characteristics promoted from the supplied CSF source where explicitly available. CSF HFI487 directly heated thoriated-tungsten industrial RF power triode with natural convection/radiative anode cooling. Continuous anode voltage limit 6000 V at the lower operating-frequency range, reduced to 5000 V at higher frequencies. Maximum continuous anode dissipation 2000 W; 3000 W is permitted only in specified intermittent service with duty-cycle constraints. Vertical mounting required.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.

No source-specific operating conditions are recorded.
