FAQ

What electrical specifications are required to operate the Atomfair AF-TCF1-3W025 tungsten coil filament at its rated temperature?

The filament requires 3 V, 42 A, and 126 W to reach its rated operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly used in the deposition system.

How do I verify that the F1 geometry tungsten coil filament is compatible with my existing thermal evaporation system?

Confirm that your source holder accepts the F1 geometry with 3 wires of 0.025 in diameter, and that your power supply can deliver 3 V, 42 A, and 126 W. The filament dimensions are 4 in length, 1 in zone, and 1/16 in format. Contact technical sales for model selection and accessory matching.

Assessment

This F1-geometry tungsten coil filament, with a 3-wire by 0.025-inch diameter construction, is engineered for thermal evaporation at 1800 °C, requiring a 3 V, 42 A, 126 W power supply. Its defined wire count and diameter provide a consistent evaporation source profile, but the fixed electrical load and geometry demand precise pre-purchase matching with the deposition system's holder and power supply.

Positive

Defined wire geometry for consistent deposition: The 3-wire by 0.025-inch diameter construction and F1 geometry provide a reproducible evaporation source profile, enabling uniform film deposition in vacuum thermal evaporation workflows.
Rated 1800 °C operating temperature: The specified 1800 °C operating temperature offers a reliable reference point for configuring thermal evaporation processes, ensuring the filament can reach required evaporation temperatures for many materials.

Trade-offs

Fixed electrical load requires supply matching: The filament's 3 V, 42 A, and 126 W electrical specification must be exactly matched to the evaporation power supply and source assembly, limiting compatibility with systems that cannot deliver these parameters.
Geometry-dependent holder fit verification needed: The F1 geometry and 4-inch length with a 1-inch zone require confirmation of physical fit within the evaporation source holder, as incompatible holders may prevent proper installation or electrical contact.
