Tungsten Point Source Filament P2 requires precise electrical and geometric matching to the evaporation system. The filament operates at 1800 °C under vacuum and must be paired with a compatible holder and power supply delivering 2.04 V, 82 A, and 167 W.

Operating Temperature: The filament is rated for continuous operation at 1800 °C, requiring a vacuum environment to prevent oxidation.
Electrical Compatibility: The source must be driven by a power supply capable of delivering 2.04 V at 82 A and 167 W to achieve the specified temperature.
Geometric Fit: The P2 geometry with 4 wires of 0.030 in diameter and overall dimensions of 4 1/2 in L x 2 in x 1/2 in must fit the evaporation source holder.
Package Quantity: Select the package size of 5 or 10 pieces per pack to match the procurement quantity.
Application Environment: This filament is intended for thermal filament evaporation in vacuum deposition systems only.

FAQ

What are the electrical specifications of the Atomfair Tungsten Point Source Filament (AF-PSP2-4W030) and how do they constrain power supply selection?

The filament is rated at 2.04 V, 82 A, and 167 W with an operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly to ensure stable thermal evaporation. The P2 geometry and 4-wire 0.030 in diameter construction define the electrical load characteristics, so confirm compatibility before procurement.

Does the P2 geometry of this tungsten filament fit standard thermal evaporation source holders?

The filament uses a P2 reference geometry with overall dimensions of 4.5 in L x 2 in x 0.5 in and a 4-wire 0.030 in diameter configuration. Fit must be verified against the specific evaporation source holder used in the deposition system, as the geometry is designed for defined vacuum source assemblies and may not be interchangeable with other holder designs.

Assessment

Tungsten point source filament with P2 geometry, 4 wires of 0.030 in diameter, rated for 1800°C operation at 2.04V, 82A, 167W, suitable for thermal evaporation in vacuum deposition systems.

Positive

Defined wire geometry: 4 wires x 0.030 in diameter in P2 geometry provides a reproducible thermal evaporation source shape for consistent thin-film deposition.
Explicit electrical ratings: Specified drive voltage (2.04 V), current (82 A), and power (167 W) enable direct matching with evaporation power supplies and source assemblies.

Trade-offs

Holder fit verification required: The P2 geometry and physical dimensions (4.5 in x 2 in x 0.5 in) must be confirmed compatible with the evaporation source holder before purchase.
High-temperature operation constraints: 1800°C operation demands a high-vacuum environment and thermal management infrastructure; improper handling may degrade filament life or deposition quality.
