What electrical specifications must be matched when selecting the F7 tungsten coil filament for a thermal evaporation power supply?

The filament requires 11.65 V drive voltage, 52 A current, and 606 W power. These values must be within the output range of the evaporation power supply. The 3-wire x 0.030 in diameter construction determines the resistance and thus the voltage-current relationship at the 1800 °C operating temperature.

What dimensional checks are necessary to ensure the F7 geometry tungsten coil fits the source holder in a vacuum deposition system?

The filament has 14 coils, a length of 5 inches, and an inner diameter of 2 in-3/8 in (approximately 2.375 in). The F7 geometry reference should be matched to the holder's coil pocket dimensions. Additionally, the wire bundle (3 wires of 0.030 in diameter each) must fit through any feedthroughs or clamping mechanisms.

What is the significance of the 1800 °C operating temperature specification for thermal evaporation processes using this tungsten coil filament?

The 1800 °C rating defines the maximum continuous operating temperature for the filament, ensuring stable evaporation rates for high-temperature materials. Users should confirm that their target evaporation material's vaporization temperature is below this limit and that the filament's electrical ratings (11.65 V, 52 A, 606 W) are sufficient to reach the desired temperature.

Assessment

This tungsten coil thermal filament with F7 geometry, 3 wires of 0.030 in diameter, is rated for 1800 °C operation at 11.65 V, 52 A, 606 W, making it suitable for thermal evaporation in vacuum deposition systems where precise electrical and dimensional matching is required.

Positive

Pre-specified electrical and thermal parameters: The filament's 11.65 V, 52 A, 606 W, and 1800 °C ratings enable direct source matching with the evaporation power supply and thermal budget, reducing trial-and-error during procurement.
Three-wire geometry for controlled evaporation: The 3 wires x 0.030 in diameter construction provides a defined filament resistance and surface area, supporting reproducible deposition rates in thermal evaporation workflows.

Trade-offs

Dependence on matched power supply: The fixed voltage (11.65 V), current (52 A), and power (606 W) ratings require a compatible power supply; operating outside these limits may cause underperformance or filament damage.
Geometry-specific holder fit required: The F7 reference geometry and 5 in L x 2 in-3/8 in ID dimensions must match the evaporation source holder; incompatible holders may need adapters or replacement to achieve proper alignment.
