This filament requires precise matching to the evaporation source holder geometry and power supply electrical specifications. The F12 geometry, 3-wire 0.025-inch diameter construction, and rated 1800°C operation define the fit and electrical loading constraints.

Geometry Compatibility: Confirm the F12 geometry and 5-coil 1x1x0.25 inch form factor fit the source holder cavity before installation.
Electrical Matching: Match the 4.44 V, 46 A, and 204 W electrical specifications to the evaporation power supply for proper operation.
Package Quantity Selection: Select the required package quantity of either 5 or 10 pieces per pack as needed.
Vacuum Environment Requirement: Use the filament only within a vacuum deposition system as specified.

FAQ

What are the electrical and thermal specifications of the Atomfair AF-TCF12-3W025 tungsten coil filament and how do they affect evaporation performance?

The filament is rated for 1800 °C operation with 4.44 V drive voltage, 46 A current, and 204 W power. These values are matched to the F12 geometry and 3-wire × 0.025 in diameter construction. The 5-coil design (1 in L × 1 in H × 1/4 in ID) ensures uniform heating. Matching these electrical specs to the power supply is critical for consistent deposition rates and filament longevity.

What factors must be verified before integrating the F12 tungsten coil filament into a vacuum deposition system?

Confirm that the filament geometry reference F12 fits the evaporation source holder. Verify that the power supply can deliver 4.44 V, 46 A, and 204 W. The operating temperature of 1800 °C is a reference point; actual performance depends on vacuum conditions and power supply matching. Also select the appropriate package quantity (5 or 10 pcs per pack) based on anticipated usage.

Assessment

Tungsten coil thermal filament with F12 geometry, 3 wires of 0.025 in diameter, rated for 1800°C operation at 4.44 V, 46 A, and 204 W, suitable for vacuum thermal evaporation where precise electrical and geometric matching is required.

Positive

High-temperature 1800°C operation: Rated for 1800°C continuous operation, enabling thermal evaporation of refractory materials such as metals and oxides in vacuum deposition systems.
Predefined electrical parameters for matching: Specified voltage (4.44 V), current (46 A), and power (204 W) allow direct verification of compatibility with available power supplies and source assemblies before procurement.

Trade-offs

Geometry-dependent holder fit: The F12 geometry and 1 in L x 1 in H x 1/4 in ID coil dimensions require confirmation of holder compatibility; the filament is not a universal fit for all thermal evaporation sources.
Electrical parameter matching required: The fixed electrical ratings (4.44 V, 46 A, 204 W) must be matched to the evaporation power supply and source assembly; deviation may cause improper heating or filament failure.
