What voltage, current, and power specifications must be matched when integrating this tungsten coil filament into a thermal evaporation system?

The filament is rated at 7.2 V, 64 A, and 461 W at its 1800 °C operating temperature. These values must be matched to the power supply's output capability to achieve the correct evaporation temperature without exceeding the filament's limits.

How does the F6 geometry (8 coils, 5 in length, 2-3/8 in ID) determine compatibility with existing thermal evaporation source holders?

The F6 geometry specifies a coil count of 8, a length of 5 inches, and an inner diameter of 2-3/8 inches. These dimensions must align with the source holder's mounting features to ensure proper electrical contact and mechanical support during operation.

What are the key considerations for using a filament rated at 1800 °C in a vacuum deposition system?

At 1800 °C, the filament emits significant radiant heat, which can affect substrate temperature, chamber wall heating, and outgassing from nearby components. The system should include appropriate heat shielding and cooling to maintain process stability and prevent damage to sensitive parts.

Assessment

Tungsten coil thermal filament with F6 geometry, 2 wires x 0.040 in diameter, rated for 1800°C operation at 7.2V, 64A, 461W. Designed for thermal evaporation source assemblies requiring a defined wire configuration and electrical loading. Available in 5-pc or 10-pc packs.

Positive

Predefined electrical loading: The filament is specified at 7.2 V, 64 A, and 461 W, enabling direct matching to evaporation power supplies and source assemblies without iterative testing.
Defined geometry for compatibility: F6 geometry with 2 wires x 0.040 in diameter and 8-coil, 5 in L x 2 in-3/8 in ID format ensures consistent fit with compatible deposition source holders.

Trade-offs

Requires precise power supply matching: The voltage, current, and power ratings must be verified against the evaporation power supply and source assembly; mismatch can cause suboptimal deposition or filament failure.
Limited to F6 holder geometry: The filament is designed for F6 reference geometry holders only; installation in non-compatible source assemblies is not supported without holder modification.
