Geometry Compatibility: Use a source holder that accepts F7 geometry with 3 wires of 0.040 in diameter and 14 coils.
Package Quantity: Select the required package quantity of 1 piece per package, available in 5 or 10 piece packs.

FAQ

What electrical specifications must be matched to operate the F7 tungsten coil filament at its rated 1800°C operating temperature?

The F7 tungsten coil filament requires 9.4 V, 78 A, and 733 W to achieve its rated 1800°C operating temperature. These values must be matched to the evaporation power supply and source assembly used in the deposition system to ensure proper thermal performance.

What are the physical dimensions and coil count of the F7 geometry tungsten coil filament, and how do they ensure compatibility with standard thermal evaporation source holders?

The filament has 14 coils, a length of 5 inches, and an inner diameter of 2-3/8 inches. These dimensions define the F7 geometry reference, which must be confirmed with the source holder before purchase to ensure proper fit.

What package quantities are available for the F7 tungsten coil filament, and how does the choice affect procurement for multi-source deposition systems?

The filament is available in packages of 5 or 10 pieces. Selecting the appropriate package size depends on the number of sources in the deposition system and the frequency of filament replacement, allowing flexible inventory management.

Assessment

The Atomfair Tungsten Coil Thermal Filament (F7 geometry, 3 wires x 0.040 in) is specified for 1800°C evaporation with 9.4V/78A/733W electrical loading, requiring careful integration with compatible power supplies and source holders.

Positive

Defined tungsten filament geometry: F7 geometry with 3 wires x 0.040 in diameter provides a standardized source configuration for thermal evaporation, enabling reproducible deposition conditions.
Explicit electrical ratings: Rated 9.4 V, 78 A, 733 W at 1800 °C allows direct matching to power supply and source assembly specifications before procurement.

Trade-offs

System compatibility required: The filament geometry, voltage, current, and power ratings must be verified against the evaporation source holder and power supply, limiting drop-in use across different deposition systems.
Limited package size options: Available only in 5 or 10 pcs per package, which may necessitate bulk ordering for high-throughput or continuous evaporation workflows.
